OSX Mail, don't let it add ZIP extension?

A colleague needs to email me a ZIP file. He's using OSX and he compresses the folder into a single file. Due to a firewall on my corporate network, all ZIP files are being stripped. I don't have the ability to disable this firewall. I asked my colleague to create the ZIP file and then rename it, giving it an arbitrary extension, I would then re-name it back once it made it past the firewall and uncompress.

He did so, and I ended up with a file called "setup.blah.zip"

I told him to turn off whatever setting was enforcing the ZIP extension anyway, he said he knows of no option to prevent this. He says OSX Mail is doing it.

I don't know Mac's, so bear with me, but if anybody knows what steps I can provide to him so that he can send me the ZIP file with an alternate extension, that would be very helpful.

Thanks

Hi

I can't be sure, but you can ask him to check out this:

The main difficulty with Mac is that they don't store file type by extension, so you can't just change the file type by changing the extension.

The OS X mail app is not adding the .zip. Not sure what is, but its definitely not Mail. Since he's on a Mac why doesnt he use stuffit to create a .sit file. Your firewall may not pick that up and you can decompress it using stuffit expander which everyone has.

And no, Macs used to use resource forks to store file type, but under OS X it's done by file extension. So no, it's not a difficulty.
