As I mentioned earlier, I can connect to other IMAP servers from
home, so it's not a firewall issue.  I connected to your mail server
"bobjr" using "telnet mail.joyner.ws 993" with no problems.

Again, I connected to your mail server on port 993 OK.

"telnet mail.trilug.org 25" hangs.

My traceroute tests from home show that I can get as far as Inflow.
But not much further.

AJ> PS - looks like I made time to write up the short description.  :)

As always, it's very much appreciated.
