Hi, I use the POP3 Connector to download e-mails from ISP. No problems since
now, but, I recently noticed, some e-mails goes to Failed mail Folder. In the
Application Event Viever register error 1056 and 1053 with the error code:
-2147220979. I detected most of this mails came from a webmail that uses a
Postfix e-mail server, and RoundCube webmail agent.
All assignments in Exchange mailbox POP3 Properties for each user are right.
I already tested in other SBS2003 servers and the same error, so I think
there's something wrong in the header.

This is the content of the .eml file located in the Failed mail Folder

After trying to look this up at eventid.net and other places, many of
the links indicate this can be caused by the incorrect POP3 Connector
info for the user account. However, since you've mentioned that the
"[...] POP3 Properties for each user are right, [...]," I assumed
you've removed and recreated them, and all was done in the SBS wizard.

I've also seen issues regarding communications between PostFix servers
and Exchange.

It could also be a POP3 scheduling issue. What is the schedule set to?
If too short, I've seen bandwidth throttling cause it because the
scheudled time between checking for new messages may overlap if too
short (such as below 5 minutes), and if there's an attachment, it may
fail.
