Send executable file to Gmail

雖然 Gmail Help Center 有提到
As a security measure to prevent potential viruses, Gmail does not allow users to receive executable files (such as files ending in .exe) that could contain damaging executable code.
Gmail does not accept these types of files, even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. Any message of this type sent to your Gmail account will be bounced back to the sender.
但是實測 Gmail 只有檔 .zip .rar
.tar .tar.gz .tgz .tar.bz2 .bz2 .gz 都可以通過
另外也可以透過改副檔名或加副檔名的方式成功寄到 Gmail, 如 file.exe -> file.exe.foo
