Hi,
Sorry if this is a FAQ. I thought I would search and find lots of traffic on this, but didn't. I found one reference to using port 26 in a thread, but I've tried that and the connection was rejected. This is the message in Outlook Express:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Default TCH account', Server: 'server31.totalchoicehosting.com', Protocol: SMTP, Port: 26, Secure(SSL): Yes, Error Number: 0x800CCC0F
Also, I thought enabling the check boxes in Accounts->Mail->Advanced for SSL would mean the traffic was sent over port 443, but by default smtp still goes out on 25, POP3 on 110 (although that changes to 995 when you check the box).
Obviously this is going to be an issue more and more. At work we will begin blocking all outbound smtp traffic not going to our own mail server. ISPs are starting to do this as well.
Thanks in advance,
Mark
