I have noticed over the past few days that mails are sitting in the internet connector queue awaiting delivery. It is takening roughtly 30mins to send an email. I checked the exchange logs and it looks like the SMTP communication between the sending server and the receiving server is resetting the connection before the QUIT command is issued. What could be causing this....may this be a problem with our firewall? I can sucessfully telnet to the receiving server ok?
