Here's more information that I should have added with the original email: 1) All attachments are under the 20mb limit, my users regularly send attachments to these same clients without any trouble 2) Server is Centos 5.3 running all up to date packages, nothing was changed/modified before this issue started happening 3) Looking through send logs shows a few differences in the errors but all seem similar:
Connected_to_x.x.x.x_but_connection_died._(#4.4.2)/ Connected_to_x.x.x.x_but_connection_died._Possible_duplicate!_(#4.4.2)/ Connected_to_x.x.x.x_but_connection_died._broken_pipe_(#4.4.2)/ Connected_to_x.x.x.x_but_connection_died._timed_out_(#4.4.2)/ Any ideas?

My users started complaining that all their emails were bouncing back. I take a look at the return errors and it says: Connected to x.x.x.x but connection died. (#4.4.2) I'm not going to try again; this message has been in the queue too long. This happens for all the emails. I check rbls first and see we're clean. Next thing I check is the recipient ips and they're all fine. I finally find the commonality between all the emails bouncing back, and it is attachments. All the emails have attachments. Doesn't matter what size, they just won't go out remotely. Sending attachments within the server to other users goes through, but to external addresses, they just get bounced with that error. Does anyone have any idea what could be causing this issue? __________ Information from ESET NOD32 Antivirus, version of virus signature database 4117 (20090530) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 4117 (20090530) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
