As a rule of thumb, surgemail doesn't modify the contents of messages at all.

So, most likely, this isn't happenning :-)

So... the trick will be to figure out what is happenning that looks exactly like that but isn't :-).  My guess is it's really something at the sending or receiving end that is going on, it could be the email client at either end...

First simplify and eliminate stuff.

1) Send the problem file to yourself. So it's sent and received by the same email client. Does it get corrupt?

2) If it does get corrupt, run 'diff or fc' on the tewo files, and send me the results.

3) Most likely it won't get corrupt, so then try with different email clients  and source/destination until you find which is the key factor.

Let me know what you discover.

My users are finding that Word .docx attachments get corrupted while the
same file saved as a .doc file (old Word) gets through fine.

Any suggestions???
