I have a quite weird problem here.
Before I start: My boss _really_ wants to send and receive exe files, and I couldn't convince him otherwise, so, as much as I would like to just let my users host their files somewhere on the internet and only mail a link, that is not possible.
So, I made sure that amavis doesn't ban .exe extensions and mailed some of them around to make sure it works.
So today, I got an angry mail in my inbox, saying that he wasn't able to send around .exe files. He attached the error message:
Weird... It wasn't a zip file.

And I am perfectly able to send around exe files using the Zimbra web client.
Does this make any sense to you? Maybe there is something wrong with his mail client?
