outgoing email problems

I am sure that this is a recurring problem with an easy fix - i just cant seem to find a direct reference to it.

I can send emails with no attachment via outlook express but as soon as I attach something i keep getting a

“time out occurred while communicating with the server” error

I have turn off outbound scanning and have increased the timeout setting to 4 minutes (from 2)

attachments are >600kb and still wont send.

sorry - not very computer literate - But getting better!!
