Slow sending internal mail

This is my problem or might not be a problem. FYI: Bandwidth throttling is not set. My understanding is if I'm sending emails internally (Same Domain) through Mdaemon it should be fast. When I send an email with a very large attachment say 30MB then I would expect it to take a max of 20 seconds, but when I start the sending process it takes forever, so I go to the MDaemon server and check the current sessions where it shows the transfer speed and the SMTP process is usually around 100 KB/Sec, which is my internet speed. I'm thinking I have a routing issue and it's going out to the Internet and back in, but say if I shut the MDaemon computer off from the internet the same speed is shown. The receiving part is fine its instantaneous I can download a 70MB attachment in a few seconds. My questions are am I missing something here, or what are some tests I can do to make sure things are running fine? I've done packet sniffing and it seems not to be a routing issue, but not positive.

Thanks for any help.
