Hi,
Attached are my quick notes on port settings and how to do by-hand
tests of connections to see if pop/imap worked, unencrypted and with
SSL. By-hand tests are a good place to start before dragging a mail
client into the picture.

Port numbers
------------
pop3: 110 pop3s: 995
imap: 143 imaps: 993
The file ssl.pop3 shows how to do a connect to a remote
host using SSL, for testing. Likewise, ssl.imaps is for SSL imap.
sample transactions
-------------------
pop3: (unencrypted)
telnet myhost 110
user joeblow
pass passwd
list
quit
pop3s: (SSL encrypted)
openssl s_client -debug -connect myhost:995
(you will see SSL stuff go by, then)
user joeblow
pass passwd
list
quit
imap: (unencypted)
telnet myhost 143
xxx login joeblow passwd
xxx select inbox
xxx logout
imaps: (SSL encrypted)
openssl s_client -debug -connect myhost:993
(you will see SSL stuff go by, then)
xxx login joeblow passwd
xxx select inbox
xxx logout
