Thanks for the suggestions. They checked the "Break apart messages" setting
and it wasn't checked. I'm waiting to hear if they're scanning outgoing mail
with an antivirus program.

Any other ideas?

A client reports that when they attach a file to an email (OE6), often
(but
not every time) the recipient receives several copies of the email and
attachment. Each time they've sent one to me as a test, I've received only
one so I don't have more details. This problem only started recently and
there have been no recent changes to their OE6 etc.

Any ideas?
