Amigos,

Here is the new policy from RR user and ISP with Dynamic IP

As part of this continuing effort, Road Runner, along with a significant number of other providers, has implemented incoming port 25 blocks of dynamically assigned IP address space, including dialup, DSL, and Cable modem IP addresses. The reason for this is because of the widespread number of high speed subscribers who we have found are infected with trojans such as Jeem, or have open proxy or SMTP applications which allow third parties to hijack them.

All SMTP error messages, sent back to the original sender by Road Runner, will be in the following format:

ERROR:5.7.1:550 Mail Refused - ISP Name - See http://security.rr.com/dynamic.htm
If you are a dynamic IP space user impacted by these blocks, then you should utilize your ISP's primary outbound SMTP server to send mail to Road Runner users. Road Runner will NOT whitelist your IP address.

BUT HERE IS THE SOLUTIONS

On exchange Administration tool, go to SMTP virtual Server properties -> Delivery -> Advance -> smat host : put yor ISP SMTP SERVER done.

Now Your sending email from Your own Exchange server with no retriction ERROR:5.7.1:550 Mail Refused - ISP Name :

We run a simple single Exchange 2003 in a LAN Environment using 443 for OWA directly.

Next to it we setup an Exchange 2010 single server by the book, all roles on this server.

All Users are on MSX2003, replication for Public Folders enable, certificates in place. Both servers run smooth creating no errors.

Problem:
As soon as a Send Connector is enable, everything works but after 5-10 hour delay,, Users on the Exchange 2003 cannot send mails to external recepients and get a "relaying error 5.7.1".

I need to delete the Send Connector and the Exchange 2003 Users can reach the external recepients again, while the Exchange 2010 Users can't send any mails to external recepients.

So I cannot use both servers at the same time which makes step-by-step-migration impossible.

Why is this relay error and how can I stop it to be able to have coexistence of Exchange 2003 with Exchange 2010?


We upgraded to SP1 recently and some users have complained that messages they send are returned with the following error:

exchange.domain.tld # #SMTP# 

This seems to only occur when the sender has an Exchange mailbox, but is submitting the message unauthenticated, using an external SMTP relay. Such as when using IMAP and submitting through their ISP's relay or submitting messages through a form. This processes worked have been working fine for us for years on 2007, and 2010 RTM, until we upgraded to SP1.

The recipients mailboxes have no restrictions and they are able to receive messages from other internal users and external users  (sent through the same relays) without any problems. 

Our Exchange spam filtering settings are set to just tag messages with an SCL and not reject them. Same for  SPF / Sender ID, we only stamp the status, no rejections. 

I searched, but was not able to find any information about the rejection, has anyone else seen this with SP1? 

When we try and send an email to a large number of people outside of our mail
server (seems as though any more than 22) be get the follwoing bounce back(a
recent development, we were able to do it about a week and a half ago)...

However, if I sent an email to say 4 or 5 individuals @syr.edu, it works
fine. When I use POP/SMTP with my SYR.EDU mail address, it goes fine to all

Could it be a Brightmail filter on the receiving side? Could it be a DNS
issue? Any thoughts would be helpful. thanks in advance.

Hello - my customer sends an email to someone@example.com, sometimes the
message gets through and other times not. She receives the following error:
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:
someone@example.com on 8/12/2005 8:32 AM

You do not have permission to send to this recipient. For
assistance, contact your system administrator.

< mia-c2.0spam.net #5.7.1 SMTP; 554 5.7.1 Command rejected>

As you can see the command rejected is coming from a different server
altogether. Are they filtering their mail through another server and this is
the server that is rejecting the message.

Why do some messages make it through and others do not ?

Basically is this our problem or theirs ?
Thanks to anyone and everyone in advance for your input on this matter.

Hello,
I have an an Exchange Server 2003 running and all has been well until I had
a power outage. Ever since that my external users using pop3 mail clients
like Outlook Express can not send mail to anyone outside the local users
group. It acts just like the relay errors but I am allowing relays and the
error is
"An unknown error has occurred. Subject 'gfgfgf', Account: 'www.domain.com',
Server: 'www.domain.com', Protocol: SMTP, Server Response: '550 5.7.1 Message
rejected.', Port: 97, Secure(SSL): No, Server Error: 550, Error Number:
0x800CCC69". I can change the rule to not allow relaying and than the error
message will switch to the "can not relay" error. I than turned relaying
allowed back on and I am right back to the error above. They can send to
users located within the local domain.
If anyone has any ideas I would be very grateful.

Cannot send email from outlook, error message 50 invalid HELO/EHLO

Hello All,

We have Exchange 2007 very basic single server setup serving some 20-uesrs.

Can someone point in the right direction.

Thanks very much...

Hello, I have seen a similar post with this error but it didn't follow my configuration so I am asking about it.The full error message is: #5.5.0 smtp;553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
I get this message when ever sending to one paticular email address, whether it is a direct send or a reply. The error only occurs on our exchange server 2003 not the Domino server (we are migrating from Notes). My organization host all it's own stuff from website, blog, to email servers. Our ISP only provides a T1 and 10 external IPs. Our public DNS records have been in place and working for some time and I can do a whois search, I have also checked blacklist and we are not on any I can find.
Thanks for your help.

This error is being reported by a few users who are on a defferent domain. Anyone that tries to send to either of these users at their domain gets this message in return:
smtp; 550 5.7.1 unable to relay for...

Anyone familiar with this particular issue?

TIA

When I put the phrase Zensoundsystems.com into the body of a message and email it from my gmail account to my exchange server I get an NDR.

I can send it with variations such as Zensoundsystems Zen.com, etc

My server is Exchange 2010 with Forefront 2010.
Any suggestions would be appreciated.

The NDR email I get is the following....

Delivery to the following recipient failed permanently:

joe@joe.net

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.

I see the below message in the Evenviewer when a programmer tries to send email to few people with a custom utility.  It used to work but not any more.  Our regular emails (email through Outlook) are working just fine.  This error comes up only if we try to use a custom built utility. 

This is an SMTP protocol log for virtual server ID 1, connection #17. The client at "x.x.x.x" sent a "rcpt" command, and the SMTP server responded with "550 5.7.1 Unable to relay for name@company.com  ". The full command sent was "rcpt TO:".  This will probably cause the connection to fail.

I've searched online but this is not a global issue with entire company, just when we use the custom utility that's why I am not sure what to look for.  Also, currently the Exchange server is forwarding all emails to a smart host which is the server with an email filter.  This particular even can't cross the Exchange server. Any suggestion would be much appreciated.

I recently migrate fron nt4/exch5.5 to win2k/exch2000. I maintain the same domain(upgrade pdc) and join the new exch2k in the exch5.5 site. All was working right until i removed the exchange 5.5. When people send mail to restricted DL, even though they are included as originators, they received the 5.7.1 error.
One interesting point is that newly created account behave correctly, only the migrated account shows the error

I have a new 2008 std R2 file server co existing with a 2003 r2 file server, both are running FSRM roles. The FSRM on the 2008 R2 server is unable to send email alerts for quota management etc. My 2010 exchange server has ALL the roles on it and has a standard out of the box config with recieve connectors and send connector. I get the `550 5.7.1 client does not have permissions to send as this sender' error in application event viewer log. I have looked at the smtp recieve logs in exchange transport and the entire smtp dialogue looks succesful.
As shown below.

Recently our Exchange server has been acting up and the application log is filling up with the following error:
*****************************************************************
MSExchangeTransport Error 7010
This is an SMTP protocol log for virtual server ID 2, connection #851. The client at "58.8.125.152" sent a "rcpt" command, and the SMTP server responded with "550 5.7.1 Unable to relay for email@domain.com  ". The full command sent was "rcpt TO:".  This will probably cause the connection to fail.
*****************************************************************

This started mid last week... Every morning the SMTP service on the exchange server was getting hung up.  I would reboot the server and everything would work until the next morning.  After reading a few articles I believe we were getting an NDR attack.  Since I've changed a few authentication settings and enabled tar pit on our exchange server it hasn't gotten hosed up.  I'm worried that the individual sending all of these emails is getting responses from my exchange server that they can use against me.  Can anyone break down the error above for me?

I've just recently converted our SBS2003 server to use Exchange.  We were using pop mail from the ISP and Exchange was not being used.  The ISP has made all the changes to the MX and host records and they should have propogated by now.  When I try to send an email to any of the Exchange mailbox's from an external source, I get a unable to relay error 5.7.1 from the SMTP server.  I can ping the mail server address and the correct IP comes up.  Any help would be greatly appreciated.

Hi All,

We are running exchange 2007 standard with SP1 and are having problem relaying message through our exchange server.

The whole exchange install is on one physical server with three roles, Maibox, Client Access and Hub Transport.

The problem is that we have a third-part software that is trying to send emails to the outside world through our exchange server.

On the Transport Rule (global transport setting) we have added the IP of this server (where the third party app trying to send email) so it should be okay to send mail. Now this server is trusted so we are fine allow it to relay emails through our exchange server.

I've tried doing the basic telnet session test from the third party server but its comming back with the error 5.7.1 unable to relay message.

I'm wondering if i need to configure another receive connector under Hub Transport?

Any suggestions?

Ash.

Hello,

I have recently installed Exchange 2003 server to our existing Exchange
organization with one Exchange 2000 server (Exchange 2000 native mode). Both
servers are members of the same admin group and the same routing group.

The original Exchange 2000 server hosts a connector and its SMTP connector
is configured to disallow any relaying (Default SMTP Virtual Server
Properties> Access tab> Relay allows only computers listed there to relay,
the new Exchnage 2003 server is not listed there). Users on the old server
can send both internal and external e-mails.

Users on the new Exchnage 2003 server can send internal mail, but receive
the NDR error when mailing outside of the organization: "You do not have
permission to send to this recipient (...) _server_name_#5.7.1 smtp;550
5.7.1 Unable to relay for _external_recipient_address_"

The only way to allow external mail to be sent from the new Exchnage 2003
server is to put its IP address on the list of computers
allowed to relay through the old server. Should I be needing to do this?

Thanks in advance for all help.

Hi,

Been struggling to troubleshoot this error message for the last couple of
days. Been struggling to find anything online.

Sending' reported error (0x800CCC78) : 'Cannot send the message. Verify the
e-mail address in your account properties. The server responded: 550 5.7.1
Client does not have permissions to send as this sender'

I have exchange 2007 hosting "domain A". Outlook 2007 using an exchange
server account can send / receive "domain A" email no problem, enternally ,
internally. I have added a POP3 account for "domain B" however, i can
receive mail, but sending email produces the error above.

Looking at the "Receive Connectors" i can see IPV4 uses 587 for connected
named "client" , i can also see port 25 is used for connector named
"default".

I can telnet to to both ports
enter helo
mail from (external domain)
rcpt to (external domain)
i get "unable to relay".

Thanks for any help

Having a unique problem with Outlook 2007 (and previously 2003) running on Windows XP with Google Apps IMAP accounts.  We are getting "An unknown error has occurred. 0x80040119" when trying to send emails.  What is strange is that only messages with local domain addresses 'stick' in Outbox (they show up with in the Outbox bolded and blue numbers beside the Outbox folder) while external messages are sent.  We cannot even open the individual messages and hit Send without getting the error message.

Test messages sent to any external domain name address goes out just fine.

I've tried the Inbox Repair Tool without any success.  They are not on any kind of Exchange server.  There are no SPF entries in the Zone File for the domain.

Any suggestions to try?

Thanks.

 

I can send emails to any outside email
but when I send it to the email accounts configured to recieve with exchange
I get this error
