That is output from an ipop3d server that allows unencrypted plaintext
password authentication.
HOWEVER, when I do
telnet trmail.triumf.ca pop3
I get the folowing:
% telnet trmail.triumf.ca pop3
Trying 142.90.100.150...

Notice that the USER capability is missing. This is why your dinosaur
clients can not log in. You evidentally have a different binary installed
than what you think you have.

Don't be mislead by the "LOGIN" authentication mechanism above. That is a
SASL mechanism, not the USER/PASS authentication mechanism. SASL
plaintext mechanisms are always suppressed.
