i think the issue is related to the mails erver, and not your database configuration settings.
Are you using your Exchange server that Outlook points to as the mail server in your database mail profile? Is it a different server?
this error message:
The server response was: 4.3.1 Message size exceeds fixed maximum message size
was returned by the mail server, so you'd have to get with the administrator the server you have set up in your profle...
for example, if you were using google mail for your Profile, it doesn't matter that you can receive 20 meg attachments, if google's mail server won't pass the a file larger than the limit THEY set, and would return that kind of error.
