Hi
Lately I've been getting Mail sending error when sending larger files ie short video attachments,Pdf files.
Text files Transmit quickly.
It seems to hang when gets up 99% when sending email message. I have one email stalled at 53% (progress status)
A few tries sending the email it will eventually will be sent.
I have no downloading issues

Virus Checker - Trend Micro
Router - netgear
Server - MTS

Firewalls - turned off

Error

" Sending of Message Failed
Message could not be sent because connecting to SMTP server smtp.mts.net failed. The server may be unavailable
or is refusing SMTP connections. Please verify that your SMTP server setting is correct and try again, or else contact your network administrator."

Any Ideas?

How big are the files?

This is more likely a provider problem or limitation than a Thunderbird problem.

File size is around 3425k WMV file

You have to ask your ISP, what is the size limit for 1 send.
...or you can split the file: http://www.gdgsoft.com/gsplit/

A 3meg file of any type is pretty much unlikely to go via any ISP that provides for the home market. Business broadband will probably be fine but home broadband packages is a different kettle of fish. Contact your ISP/email provider for any limits on files.
