Problem sending email from isp to Exchange

[Kyusaku]

Hi,

For about a month now, more and more users have been complaing about their inability to send email to our exchange server through their local isp. Downloading via pop3 has never been a problem. Originally we were having them relay through their isp to our mail server for authentication. After this quit working (isp more than likely not allowing relaying) we started switching their outgoing to the isp's mail server. This doesn't always work either. Could any of this be in some way related to our exchange 2000 server? If more detail is needed please let me know.

Thank you

Same issue here with outside sales reps, anyone have any suggestions?

I have solved the problem, I setup another smtp virtual server at a higher port number and had our field offices change their outgoing smtp in Outlook to use the new port number. This has been sucessfully everytime. Of course we are still using port 25, but the higher number is for our field offices.

I hope this helps...
