E-mail doesn't send over 2MB

Hi all,

I'm sure what i am missing here. Whenever I try to send an e-mail around 5MB
or so, Outlook 2003 says it is sending it and then doesn't. I get a message
saying the following in the 'SEND/RECEIVE PROGRESS' window. I called my ISP
(Shaw) and they said it is my CA Antivirus. So I disabled it. Still did the
same thing. 5 minutes later, the attachment (PDF 6MB) shows up. I have no
idea what is going on. Is there a setting in Outlook I should be looking
for. I never had this problem before.

Task 'shawmail - Sending' reported error (0x8004210B) : 'The operation timed
out waiting for a response from the sending (SMTP) server. If you continue
to receive this message, contact your server administrator or Internet
service provider (ISP).'
and
Task 'shawmail - Sending' reported error (0x800CCC0B) : 'Unknown Error
0x800CCC0B'

Thanks in advance.
Sam

What is your e-mail provider's anti-spam quota on maximum size per
e-mail?

If you are sending a 5MB e-mail, it isn't just text or even just HTML.
You are sending binary content, like executables or images. ALL
e-mail - and I mean all e-mail - gets sent as plain text. Binary
content is encoded in plain-text sections within the e-mail.
Converting binary to text will enlarge the e-mail by 2 to 3 times the
original size of the binary content. You might think you are sending
a 5MB image attached to an e-mail but after encoding that e-mail ends
up exceeding the 10MB/message anti-spam quota on your personal e-mail
account.

If you enable e-mail scanning in your anti-virus software, especially
for outbound e-mails, then obviously that anti-virus program has to
interrogate that huge message to scan for pests before it then gets
passed to the mail server. This means that after your e-mail client
has told the mail server that it is sending a message that your
anti-virus program then delays delivery of that message while
interrogating it, and that delay exceeds the timeout by the mail
server figuring that what you said you were going to send isn't really
forthcoming.

Thanks very much for your responses. I am guessing from this point it is
between my CA Anti-Virus which does scan outgoing e-mail, the fact that I
had my Windows firewall engaged while using my Linksys WRT54G router (which
I am told not to bother using both) and perhaps my MTU which is set on the
router to 1300 should be set back to AUTO. I am trying to work witht his as
well.

Great assistance from both of you and again I appreciate it.

Sam
