SMTP Not Available Outside Network
Posted on 2010-08-19
I am trying to set up IMAP access for my mobile users. I have opened the appropriate ports in the firewall (993,25) and, as far as i know, configured the SMTP connector, and the SMTP virtual server correctly.
I can set up IMAP and SMTP inside the network, and it works fine. I can telnet to the aforementioned ports, and they respond as they should. The problem is, when I try to set up an email client from outside the network, the SMTP service does not connect the the network. Furthermore, I cannot telnet to port 25. I can connect to the IMAP port, but not the SMTP port. When i telnet to port 25, all i get is a blank screen with a blinking prompt.
Any help would be greatly appreciated.
