The link in the error message says that the server is receiving bare LF
characters. I've not known OE to do that.

Since the problem is happening with just some attachments, I would
suspect your anti-virus. Did you uninstall and reinstall the anti-virus
in Custom mode without e-mail scanning as Bruce suggested? Otherwise,
your anti-virus is likely still scanning the message and potentially
corrupting it.

If you are using Stationery or a Signature in OE you could try turning
those off in case either of those has the bare LF (Tools, Options,
Compose and Signatures).

Turn off e-mail scanning in your anti-virus program. It is a
redundant layer
of protection that eats up CPUs, slows down sending and receiving,
and
causes a multitude of problems such as time-outs, account setting
changes
and has even been responsible for lose of messages. Your up-to-date
A/V
program will continue to protect you sufficiently. For more, see:

Note that for some AV programs, it may be necessary to uninstall the
program
and reinstall in Custom Mode and opt out of e-mail scanning when the
option
arises.

I have a new computer with XP. About 3 weeks ago, Outlook Express
started
not allowing me to forward mail with attachments. I get the
following
error
message:

Your server has unexpectedly terminated the connection. Possible
causes
for
this include server problems, network problems, or a long period of
inactivity. Subject 'Fw: Bush's "resignation" speech', Account:

My contact person at my ISP has no clue. I don't have many, but
think it
is
probably something in the OE on this computer, as I can forward
messages
with
attachments from my lap top.

Will appreciate any help. I have made OE the default mail
handler - to no
avail.

I turned off the e-mail scanning before posting. It seems to be
selective about the attachments it won't forward. Week before last,
I had a message that had several "Maxine" cartoons attached and it
wouldn't forward it. I am at my wit's end. Don't feel qualified to
remove IE (if that's what it takes to remove OE) and reinstall it.
