Here are some strategies to cope if you are sending something useful:

• First of all, ask yourself if it is really necessary to transfer this file type? Many Email users can either refer to an official site to download executables, or offer a suitable channel for distribution without resorting to attaching it to an Email.
• post it to a website and refer to it.
• post it to a FTP site and refer to it.
• some data may be inlined directly into mail (e.g. URLs).
