Hmm... I would suspect that to be the case in other circumstances. But in this case the email originated from our user, and the NDR came from our domain's postmaster account. It never made it outside of our server.
I know how to get around the error; I'm trying to figure out why it was an error at all, and what, if any, setting I can change to avoid seeing it again. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christopher Checca Sent: Thursday, April 14, 2005 9:19 AM To: IMail_Forum@list.ipswitch.com Subject: RE: [IMail Forum] Unusual NDR Sounds like they block zip files that they can't unzip and antivirus scan correctly. I would tell them to resend the email without being in a zip format. Christopher Checca Packard Transport, Inc.

I had a user send a zipped text file to an outside client, but Imail blocked it and sent back the following: >undeliverable to <email address> >Body of message generated response: >551 Message contains a ZIP file that is extremely compressed (97.02%) Any ideas why this happens? Is there some setting that I can change somewhere? I checked the KB, list archives, and online discussion forum, but came up empty-handed. TIA for any help.
