Starting end of April, few certain users(bbbb.com) reported they didn't receive emails sent by some certain people(aaaa.com).  The senders didn't get any undelivable message.  After a request to the senders for resend, the emails get thru.  Occasionally the senders need to try (send) for three times.  Emails sent from other sources seem to be OK so far for the repipients.
We've be bothered by this mystery for more than one week.  Would you please help?
Sorry I only have 70 points to offer.

P.S.  aaaa.com has box size limit but bbbb.com doesn't.

Check your mail server logs on aaa.com to verify the mail was sent successfully.

Check the mial logs on bbb.com to verify the mail was received successfully.

If both are successful, then check that the recipients in bbb.org are "misplacing" the mail messages on their clients.

7 times out of 10, if you are not receiving any errors or warnings on your mail servers, its "operator error" and not a mail server problem.

I got the same problem. I only experience this last week and I can't find any problem on my Exchange server.
I also have cases where I can't receive mails on that particular sender but there are days that I can. I checked on the sender and they told that there server are working fine. What can be the cause of this problem?

If i had to bet money, i would say it is aaaa.com that has the problem. Whether they are having DNS or routing issues, (they might possibly have multiple Exchange servers doing their routing) usually it is not the receiving server that is having the problem, especially if the sender will get through the second or third time. Of course bbbb.com is going to say their server is fine, but to be honest with you, this is real Sherlock Holmes work. The only thing you can do is alert the administrator at aaaa.com to enable some sort of message tracking, then when a user in aaaa.com complains of the issue, have THEM track the message to ensure that it is leaving their organization.

I know this is kind of throwing the blame, but my guess is...it's probably an issue with their server.

Hope this helps.

I agree with what Kevala said.
I have created the same problem for receiving site, First af all, I check my Exchange 2000 and consult with the Microsoft Support Team, Everthing is fine. I set up 3 of Exchange Server 2000 without SMTP connector, according MS said Virtual SMTP server is able to handle the messages. For a while, I still hear the problem. So I decide to install SMTP connector to 3 Mail Server, Suprisely, All the related problem gone.
