452; Too many recipients received this hour


Hello,

I have been receiving a few NDRs stating "452; Too many recipients received this hour". They seem to be created from emails going to the same location (our other office) which controlls their own mail. I don'tknow if the problem resides on my end or their end. They have not received the messages we got NDRs for, that much I know.

Could anyone tell me what are the best things on my side, Exchange 2003 SP2, that I should look for? If it's on their end, I would at least like to be able to confirm that anything related to this message on my end is set correctly.

My server is newly up and running, so I'm afraid I don't have any history of emailing this location through this Exchange server successfully to compare recent activities to.

Thank you

Hi Everyone.

Got a bit of a problem. Whenever my users send an email to this one particular company, 30% of the time, the emails don't go, and the user gets the mesagefrom the exchange server:

The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.


The company that is supposed to be receiving the emails says that they do not have any problems. Any ideas?




I have been receiving the following in outlook

Your message did not reach some or all of the intended recipients.

error 452 too many recipients. Does it mean that I have too many individual
addresses in a group?




I sent an e mail message to25 clients and got a message back from System
Administrator " Your message did not reach some or all of the intended
recipients"
Under each of the email addresses it said " 452 Too many recipients"
This has only just started this year.
Any Help

Hello,

we're have a fixed IP and are sending directly with DNS (public IP address port 25 transparently NATted thru the firewall/router).

One of our customers (to whom we have to send a lot of mails) uses something like a greylisting function. The first mail is refused with SMTP error 452 "too many recipients received this hour". The second message then gets thru... *if* there aren't too many messages waiting, that is...

I reckon that this SMTP error code is a "transitional" error, and that the sending server should retry sending after the configured delay time. However, our server is not waiting with the re-send, but retries sending *immediately*. This results in way too many connection attempts per hour, and the receiving server is eventually blocking the message entirely (the sending user on our side gets an NDR with the aforementioned 452 error).

I have little (or rather: zero) influence on the spam filtering/greylisting functions on the recipients side (and I don't think that greylisting is a good solution, but who am I...), but I do have the feeling that our Exchange server is behaving incorrectly when it retries sending without any delay (the same second, to be precise...).

Is there any way to influence this behaviour locally (on our side of things) other than using a relay?

Thanks in advance...




I contacted comcast and they said that the recipient issue is within Outlook,
and that they have no limit. I am trying to send to a distribution list, and
get the message each time (452 too many recipients, send more in a second
session). Any suggestions?

Hello,

I posted on this issue the other day. It was suggested that the problem might be anti-spam related. I now believe it is not that. If I could give some more information, hopefully someone will have some ideas?

My company has two offices and has used the same pop mail for years. We have 75 mailboxes hosted through a company called Value Web. Both offices configure Outlooks incoming/outgoing mail servers as such:

Incoming: pop.mydomaininc.com
Outgoing: smtp.OurISP.com

Our outgoing mail goes through our ISP and we authenticate for relay purposes.

I have recently set up my Exchange server and have migrated 7 users, including myself, to it so I can do testing on a small number before I bring everyone over.

When we send email to people at the old pop account (i.e. joe@mydomaininc.com) some of them fail and we get NDRs stating 452: too many recipients this hour. I used to think this was related only to mail going to our other office. I now know it is true with mail going my own office as well. So the idea about it being anti-spam at the other office is not the case.

I know the virus/spam software used at both offices. I also called that manufacture and they confirmed there is nothing that the software would do to cause that. The thing is, my Exchange server only processed approximately 100 pieces of mail today between the 7 people, incoming and outgoing combined. We are not heavy email users compared to many places.

In some case, the failed piece of email was the ONLY email sent or received that hour! So how could there be too many recipients that hour? That was the only one that hour!! And we are not sending to just one person at the pop domain. So its not enough mail going to any one person for the anti-spam software to become suspicious.

We have not received an NDR to any other mail addresses other than this one. So happens its the one we use the most. But again, we dont send that much mail to it to be a problem. There has to be something tied to my Exchange server that is causing this problem. I have tracked the messages but I dont get much more info through the exchange tracking system than I do the NDR itself.

I could really use some help. I want to migrate everyone to Exchange, but I cant have this issue multiplied by 150 people. I wouldnt be very popular then, would I?

Thank you!!!




One of our remote users encounters this from time to time sending to a list
of 20+ recipients. She encounteres the 452 too many recipients. I confirmed
with our ISP aka the SMTP server that there are no limits to recipients only
number of emails per day (i.e. 2,000+)

I have asked that she capture the message header from this "system
administrator" as it is not clear if it's an Outlook thing. I am sure it's
not the ISP. Do any of you use an AV / Internet security product as well ie.
Norton Internet Security?

I suffered from this problem for months; I had trouble blaming the ISP
because the error message in the In Box came from "System Administrator",
whose properties did not include an Email address, because my ISP would not
confirm the problem, and because the problem would not occur if I sent using
the Email address I had in my ISP's domain. My Email would be sent to no
more than 5 recipients at a time.
The only way I found around this problem was to simply resend the Email
(using the edit and resend commands); the new Email would go to the Out Box,
and after typically 20 minutes, would go out again as if by magic, yielding
another error message if the number of recipients was still higher than 5. I
would repeat this process until all the intended recipients would be covered.
Now, to Jocelyn's point, the problem went away when I happened to switch ISP
(to SBC from AOL). I don't know what my recipient count limit is now, but it
seems to be higher than 20.
Hope this helps...

When I send an e-mail to multiple addresses using BCC and a Distribution
List, Only some of the list seem to go sucessfully, most seem to fail as
indicated bt an e-mail received imeadialtly the send is finished from the
"System" Subject: Undeliverable,
and in the body of this e-mail the following information is typical:--

Your message did not reach some or all of the intended recipients.:

Subject: Geraldine Latty Tour in January.

The following recipient(s) could not be reached:

'Graham Smith' on 15/12/2008 10:19
452 4.5.3 Error: too many recipients

This infomation is repeated for between 5 and 40+ recipents.

I am using Windows XP Pro SP3 Office 2003 SP3 Outlook 11.8217.82221 SP3.

My outbound mail is destined for SMTP.Orangehome.co.uk. They say there are
no limites applied by them.

I POP from my mail provider at POP.1and1.co.uk they also say there are no
restrictions.

If the number of e-mails is low 1 to 8 say the problem does not arise.

There is one other factor which may or may not be relevant. The error report
e-mail I get is very clearly cut and pasted above. If I send it to another PC
and they open it the error report line can be different so it looks as if
this information is dependent on the machine on which the message is
opened????

I do do 1 to 5 e-mails a day to groups or 2, 10, 50 and any of the 10 plus
will exhibit this type of problem. If I edit the list and send those listed
in the error report most will go but a shorted list of errors will be
reported.

Please help I am desperate. I can forward copies of th original e-mail plus
assocciated error reports if you wish.

Regards and thanks for the hope of a solution.

We have a couple people out in the field, using POP3/SMTP access, and they get this message quite a bit. it seems to limit around 32 recipients.

I cannot figure this out. I seemed to start happening 2 weeks ago. I've checked all limits in Exchange manager, SMTP Virtual Server. and cannot find where this limit is set.
The odd thing is, it works fine through Exchange, Webmail, and VPN. Thanks for any suggestions.




When attempting to send to 25 (Twenty Five) recipients, I get error message

so, how please!!

The second email was from some





Dear Support,

I've done some serches and not sure where the limitation is coming from. Under Organization configuration | Hub Transport | Global Settings | Maximum number of recipients are set to 5000.

Thanks for any help you can give!

My wife is part owner of a business and she sends out weekly emails to approx. 2000 customers. She has four different Group Contact listings. She has been doing this for the last 3 years with no issues. She is now getting the following message:
The following recipient(s) cannot be reached:

I have contacted our ISP but they tell me there is nothing wrong with the server and that it is a microsoft issue and to contact them. She is using Outlook 2007. She got these messages last night and tried again today with the same result, she is not able to send her emails anymore. Any suggestions would be appreciated. Thanks,

Hi,

Exchange 2007 mail system. Now we have a problem with some mails deliveries.

Get-TransportConfig
MaxRecipientEnvelopeLimit 250

Receive Connectors
MaxRecipientsPerMessage 5000

But one user has been configured with
MaxRecipientsPerMessage 9999

This user send an email with 600 recipients in the "To" field. Exchange returns this error message: "550 5.5.3 RESOLVER.ADR.RecipLimit; too many recipients"
How can we do to limit all users to 250 recipients but some mailbox exceptions that can put mor than 250 at the "To" field?

Regards,
Tim
