GMail Email Attachment Policy

As a security measure to prevent potential viruses, Gmail doesn’t allow you to send or receive executable files (such as files ending in .exe) that could contain damaging executable code.

GMail doesn’t clearly define what kind of file extensions fall within this list. Apparently .js (Javascript files) are included too.

Gmail won’t accept executable files even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. If this type of message is sent to your Gmail address, it is bounced back to the sender automatically.

Interestingly GMail doesn’t mention bz2 so most likely it accepts bzip2 compressed files. Also aren’t mention jar and war format. It is worth testing them out.

You can send and receive messages up to 20 megabytes (MB) total (including attachments). Any message that exceeds this limit will not be delivered to your inbox and will be returned to the sender.

A way to send a executable file is just renaming the .exe for anything else gmail may accept, like .JPG
