Are you kidding me?
The solution to the issue attaching EPS files to Mail it to not mail EPS files or use another program if you do?? Please tell me there is another solution.
Macbook Pro, Mac OS X (10.5.4)
Question: how large is this EPS file you are trying to email? You should not email any file larger than 5 MB. Instead, you should use some kind of FTP program or web file sharing site such as DropBox or YouSendIt.
Also, you should compress the file into either a .zip or .sitx file before attaching it to an email, even if it is under 5 MB in size.
Since you are using a MacBook Pro, select the file in the Finder and under the File Menu choose "Compress..."; this will compress the file into a .zip archive. Then, attach that file to your email.
