It appears that the dial-up section of that article applies to Win98.
I've done some digging, but haven't been able to identify how to change
the MTU for dial-up in XP.

I've had a look at this article, Michael. However, the Registry key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Class\Net\ quoted
in
the article has many many sub-keys listed under Services, but Class is
not one of them. Any thoughts as to why that might be so?

I'm using WinXP Home SP2, IE7 and OE6.

Thanks for the various suggestions.

I use an anti-virus program, but the email checking element is
turned off
(and has been for many moons, as has often been suggested in this
newsgroup).

I tried setting the Server Timeout to 5 minutes, but the only
difference
is that the OE message now says ""Your SMTP server has not responded
for
300 seconds ..." g.

I then tried the option 'Break apart messages larger than ... KB"
with
150KB and then 100KB, but still it appears to get about 1/4 of the
way
through the first Part, then stops until the dreaded timeout message
appears after 5 minutes.

Any other ideas, please?

AFAICT there is no such newsgroup (and my News server doesn't allow
crossposting to groups which it doesn't carry).]

That's not all that large even for Dial-up.

Not large, but probably too time-consuming.

275KByte is 275 * 10 = 2750 Kbit. At 56Kbit/sec (*maximum* modem
speed) that is 49 seconds. As his time-out is only 60 seconds, that
is
easily reached if the *throughput* is less than 56Kbit or/and the
modem
speed is lower than 56Kbit.

While I take your word for it that anti-virus scanning is often
the
cause, in this case it is wise to *also* make the time-out bigger:

Tools - Accounts... - click on the applicable Mail account -
Properties - Advanced - set the "Server Timeouts" to "Long" (5
minutes).

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:
http://www.oehelp.com/OETips.aspx#3

In Tools | Accounts | Mail | Properties | Advanced, move the
Time-out
slider
all the way to the right, (5 minutes).

I'm currently using a dial-up connection, as I am temporarily in
Perth.
I've tried many times to send 2 emails with attachments of 195KB
and
275KB. Every time it fails and I keep getting messages saying
that
"Your
SMTP server has not responded for 60 seconds ..."

Does anybody have any suggestions about what is causing this?
I'm
using
OE 6.0 and have no problem sending smaller emails (such as this
post).
