NNTP and IMAP can also exist in the same area, so clarify
that the username + password is only for POP3
POP3 access is available:
$urls
-The password is: anonymous
-The username is: \$(uuidgen)\@$ctx->{ibx}->{newsgroup}
+The POP3 password is: anonymous
+The POP3 username is: \$(uuidgen)\@$ctx->{ibx}->{newsgroup}
where \$(uuidgen) in the output of the `uuidgen' command on your system.
The UUID in the username functions as a private cookie (don't share it).
Idle accounts will expire periodically.
