mail queue errors sent to other users on server

[gckorn]

This is complicated so let me set this up so you can understand it:

1. Assume there is a message in the outgoing queue from an on-server user, [email protected]. The message is sent to 200 recipients, included among these recipients are [email protected], [email protected] and [email protected]. The message has a large attachment (400 MB) that obviously is rejected by many ISPs.

2. Now, I happen to send an email to [email protected]. That new email is from [email protected]. That is, server-to-server email.

3. When I send this email - a mail from [email protected] to [email protected], I get failure messages that pertain to the message from [email protected] that is on the queue. That is, I will get a failure message stating that the mail to [email protected] is too large and is rejected by that ISP, that the mail to [email protected] is too large, etc.

Obviously, something is wrong, as I should not be getting failure messages that are intended for [email protected].

Any thoughts about the problem? How to fix it?

Thanks,
