Email rejected by

I need some help with an email rejection issue. Since last week, many of our
outgoing emails have been rejected and the common source has been microsoft
(hotmail) or something from I have done some research online
and haven't found anything useful. Anyone has any ideas or thoughts? It
looks like we may be on some blacklist from bigfish, but I am not sure.

Any ideas would be great.

I have been using alltel wireless internet with the outgoing server ( Due to the merge of alltel and Verizon, there have been some changes. I was told by Verizon tech support that I needed to change my outgoing server to ( all outgoing email addresses are being rejected by the server.

Anybody know why?

The error message is below:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'emailaddress'. Subject 'Re: gore, clinton & obama go to heaven', Account: 'Business', Server: '', Protocol: SMTP, Server Response: '550 5.7.1 ... Relaying denied. Proper authentication required.', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

We finally got our Edge server and it is working well.

the newest problem is that I am getting reports of email being rejcted. When I was running just Symantec I could easily look it uip. Now that I am using the Edge server for spam it is bit different with the log file in the Exchange shell.

Is there a cmd just to retrive emails that have been rejected by receipiant? By that I mean if calls to tell me that his custoemr got an NDR or the email did not arrive, I would like to see all the emails that were sent to that were rejected. #5.5.0 smtp;550 DY-002 Mail rejected by Windows Live Hotmail for policy reasons. The likely cause is a compromised or virus infected server/personal computer. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit for email delivery information and support>
I've checked dns / reverse dns / spf .  I am missing something, I cannot find any way to get thru to someone to help. We had a virus 2 months ago and got blacklisted, We are off all lists now and still can't send mail to hotmail accounts.
Tried a second conector accross my provider and get this error:

there was a SMTP communication problem with the recipient's email server. Please contact your system administrator.

Hi Everyone,

About 1 month ago we migrated from a W2K/Exchange 5.5 server to a
W2K3/Exchange 2003 server. The 5.5 server has been deprecated.

From time to time, incoming messages are being rejected from users that at
times they come thru. I'm suspecting a DNS problem but really don't have any
idea of what is going on.

Again, we have received emails from this user many times and this is
happening with several users randomly. Here is a sample of what one of those
users is getting when the message gets rejected by our server:

Reporting-MTA: dns;
Received-From-MTA: dns;
Arrival-Date: Wed, 11 May 2005 15:53:36 -0400

Final-Recipient: rfc822;
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;500 Syntax error, command unrecognized
250 OK
220 have no reverse-DNS (PTR record) assigned.
ions from IP addresses which
220 have no reverse-DNS (PTR record) assigned.

..5 ... Recipient ok


We've got a new exchange server, plus various other changes/upgrades
(active-directory, a new barracuda spam filter).

Anyway, most email we send is okay, but when I send to an ISP called
plusnet, it gets delayed with a status of 4.4.7.

AFAIK this signifies rejection by the receiving server, so I'm guessing that
there is something in the headers they don't like.

Here is a sample header set - anyone have any idea why it might be rejected
(and what we can do about it)?

When I create a new user or distribution list on my Exchange 2007 Hub/Mailbox/CAS, messages can be sent internally to this address without a problem.

Any messages sent from the Internet to these new addresses are rejected. Sender gets the following:

This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
PERM_FAILURE: Gmail tried to deliver your message, but it was rejected by the recipient domain. The error that the other server returned was: 550 550 5.1.1 User unknown. We recommend contacting the other email provider for further information about the cause of this error. Thanks for your continued support. (state 14)

Agent logs on the Edge server show the following:

I have performed a number of "start-edgesynchronization", restarted all services on both the hub and edge servers, restarted both servers. I
removed the subscription from both edge and hub, ran “new-edgesubscription” on the edge to generate a new XML key file, imported it to hub, and force an edgesync by running “Start-EdgeSynchronization”.

If I run
Test-EdgeSynchronization -VerifyRecipient on my Hub Server, I get the following response:

Hello, we have been experiencing a strange problem with our Exchange 2000 server for a few months now but recently it has started to become a bigger problem.

When sending emails to SOME addresses on our main domain we get this reject message (this is from gmail but i get a similar response when I use my yahoo account to send the mail.  I replaced or removed my real email addresses with dummy account info):

Delivery to the following recipient failed permanently:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Invalid recipient (#5.1.1) (state 14).

This account (not my real domain obviously) is a secondary address I gave myself under my regular AD account.  I can send emails to my main address but not to this secondary address so I know my account can receive mail.  However there are some users who are rejected even if the mail is to their primary address (in fact several only have the one main email and it rejects every time) so I know it is not a primary vs secondary email address issue. I have also swapped the primary/secondary emails under my account and it made no difference, I could still send to the main address but the "test" account fails.  Furthermore, we have a second domain routing mail through this same exact mail server and all of those email addresses seem to work fine.

I have tried to edit Recipient policies in Exchange to no effect (which seemed to make sense since I can receive some mail to my account).  I've tried deleting addresses and adding them back in to no effect.  I've tried all sorts of changes to Exchange (to the point of actually breaking mail all together, then fixing that but still having this same problem).  There are also no problems when sending mail internally, this is only an external email issue.

I'm at a loss to figure out why this is happening.  If anyone can shed some insight into this issue and point me in the right direction I would be very grateful.


All email sent from outlook are now rejected by the domain of one of my
correspondents. They had recently upgraded their anti-spam filter to check
that the message ID of incoming emails is valid. Here is the rule that
outlook, as set up on my computers, violates:

533 5.7.1 Illegal Message-ID

RFC 2822 requires each mail to have a unique Message-ID. Your mail had a
message-ID ending in "@localhost" or "@localhost.localdomain". So there is
no guarantee it is unique. Hence your mail was rejected.

Remedy: Configure your mail software and/or your host/mailserver correctly
so your Message-ID ends in your fully qualified domain name.


the message ID that outlook generates does indeed end in "@com" and so
violates this rule, which is said to be an internet standard.

How can I change the domain name so that it has a proper domain name
rather than just "com"? Is this controlled by outlook? I am send/receiving
by SMTP/pop3, with the outgoing SMTP host being IIS on Windows 2003 server.



The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ''. Subject 'test', Account: 'Golden Eagle', Server: '', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

After migrating to Exchange 2010 I now have some clients who email us that are hosted through Microsoft that will receive Delivery delays to us and also sometimes 4.4.7 550 smtp expirations. This does not happen all the time and I have yet to find a rhyme or reason to why they would get it. One thing I do notice though is that the server in teh undeliverable always says which is Microsoft's online clients server. I have already increased my header size, I have made sure my spf is correct and dns records. I even created a transport rule for one of the clients to always allow their emails to come through without checking the spam level so I really don't think the issue is with our setup. I verified with our Barracuda Spam Filter vendor that everything is correct their. Any thoughts? Has anyone ran into this and can provide any help. I appreciate it.


We have an SMTP connector (using a Smarthost, not DNS) in our Exchange 2003
org that will route out mail that it does not find a recipient for for a
certain domain in Recipient Policy. Let's call it:

So if no one in our Active Directory has the email address it will route that mail out via this connector directly
to an Exim mail server that currently hosts the rest of the mailboxes (We
are in a migration stage, getting the Exim users over to Exchange 2003). It
is running Exim 4.43 (that's what it says when I telnet to it).

Not all mail is getting to it, that is the problem.

Some mails are returned stating:

Action: failed
Status: 5.6.1
Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote Host

This only tends to happen when a mail is forwarded through the connector
when recieved by Exchange from certain web mail clients or programs. For
instance if we send an email from another Exchange Org using Outlook then it
is recieved and then sent along the SMTP connector to the Exim mail server
fine and the mail is recieved.

However some people using webmail clients from other ISPS are getting the
above error.

I've got a feeling this is a 7BIT/8BIT MIME problem so what I did on the
SMTP connector was disable ESMTP (effectively saying HELO instead of EHLO)
in the hope it would fix it and convert the mail correctly so that the Exim
4.43 mail server could recieve the mail.

However it still isn't..

Again this is only happening with certain mails. It all depends what format
the message is recieved by Exchange it appears.

Anyone ever had this before? Is this a shortfall with Exchange or Exim 4.43?
Can it be fixed?



Hi, this is my first post on here. I hope someone can help me out.

A company that we do business with have set up a competition where someone enters their email address and the answer to a question and then their details get automatically emailed to us and them.

The way they set it up initially was that the emails would appear to be sent from the person entering the competition, therefore the web script would effectively be spoofing their email address, like spammers do.

I was a bit concerned at the way they'd chosen to set this up so I spoke to them and they have since changed their setup and are now sending all the emails to us from a single email address which has their domain name in it.

We are still getting emails rejected by IMF and some are ending up in the junk mail folder but others seem to be received OK.

What would be the best way of solving this problem? I don't want to turn off IMF or even adjust the settings of it as it currently works pretty well at blocking a lot of spam.



On a SBS 2003 Standard Box, we have the following issue:
the SBS is the default outgoing SMTP server for a typical small local network, i.e. range can be used by any computer or software or other device (mutli-function copiers) to send e-mails via SMTP (standard port 25/tcp, no authentifcation needed) - it tested and works perfectly, we can by example telnet the Exchange of the SBS and send e-mails in command line, no problem
a router is connected to the same subnet than the SBS ( and in this router there is a route to allow a sendmail server (Linux) to send e-mails via the SBS from another subnet ( problem is: the SBS seems to reject packets which are not coming from its own subnet, i.e. and of course we are not administrators nor of the sendmail nor of the router and we cannot ask to NAT the packets coming from the sendmailPlease note this not an issue related to the config of Exchange itself, we checked it and we're sure that it doesn't filter trafic coming from The proof is that if we activate the SMTP logs, there are no sessions opened from the sendmail to the Exchange.

We think the Exchange does not receive SMTP communications because the SBS does filter all communications not coming from its own subnet. We can't even ping the SBS from when we can ping it from any host on the subnet.

We tried to virtualize a small config to test it and we can see that a standard Win2K3 Server accepts to be pinged fro another subnet when a SBS does not.

For info, here is the way we used to test:
created a Linux VM with one NIC only, in a different subnet than the subnet of the Win2K3 Servercreated a second Linux VM with 2 NICS, one in the subnet, the other in the and we activated ip forwarding in this hostin the 1st Linux VM we indicated the second Linux VM as gatewaythen we tried pinging the Win2K3 Server from the 1st VM through the 2nd one, generating IP packets coming from one subnet to the other.Packets are accepted when the Win2K3 in not SBS, rejected when it's SBS.

I repeat this SBS is a standard one, so there's no ISA on it.

So we think there is somewhere in the SBS a filter to reject packets coming not from the SBS subnet.

Does anybody know this feature in SBS and where it can be changed?

Please help - this is a very blocking problem - we are not able to relay emails generated by a Web server via the sendmail and the end user of the public website of our client can no more receive their logon info when they register on the client website.


how to set under send/receive email account by email name in microsoft outlook

At time i want to receive mail only and when in microsoft outlook under
send/receive button pop down all account is like show thus i
am unable to find proper email acccount under that , as i

be view ,, but insted of this shows and, i have 50 accounts under same, then how can i select to check only specific email id.,

please send me solutions if you know,

I have a web page and have email directed to my home computer. When i tried
to send a message using my web email address it would not mail. Message
reads one of the recipients was rejected by the server? Don't know why?

This happens with Outlook 2000 and Outlook Express. I cannot post to a
newsgroup with an attachment. I can receive newsgroups with attachments. I
can send email with attachments. But I cannot post to a newsgroup with an
attachment. I get the following error.

Outlook Express could not post your message. Subject 'Is this a font?
Anyone got one close to it ?', Account: '', Server:
'', Protocol: NNTP, Server Response: '441 Posting
Failed (Rejected by POST filter)', Port: 119, Secure(SSL): No, Server Error:
441, Error Number: 0x800CCCA9

I thought problem was with my server, they say its Microsoft.

I've noticed that any emails sent by my MSN POP3 account to any Yahoo email
address ([e.g.

When I try to send a message with Outlook Express 6, I get the following

"The message could not be sent because one of the recipients was
rejected by the server. The rejected e-mail address was

'554 : recipient address rejected: relay Access

I have tried several things such as checking for virus', spyware, Hijackers
etc and the system is all clear on that front. I have tried to disable both
the firewall and the anti-virus programs but that diddnt help. I have
downloaded all windows up dates, including IE7 (but this problem happened
with IE6 too) and any other program files I could find. I have also removed
and re-installed OE6, ran a windows repair and called the ISP who assurs me
that the email is working fine as I can send via their server based web mail
system. After all of this, nothing has worked.

Any ideas folks?

Has anyone else noticed a 48-56 hour delay getting mail through

exchange message center track email sent by an application?
Is the above possible?


Exchange 2k3
AD 2k3 mixed

I am wondering if it is possible to track email volumes by user?

From what i can tell it doesnt seem to be possible, i can perfmon volumes
for sent and recieved but its not by user. As far as i can tell there are no
perfmon sets that do anything by user.

3rd party?

Is it possible to get the actual email content by the message-id rather than
routing information without using any sort of 3rd party software?

Or does exchange not store this information because its up to the client to
associate the sent email w/ a specific account? (meaning the client says,
store this in the Sent Items folder")

Pretty much I need to see more information about a specific email to verify
whether or not they sent a certain file attachment or not.
