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.
