Not necessarily, Courier imap imapd and imapd-ssl can be configured to
use STARTTLS on port 143 to enable TLS (read the configuration files
thoroughly).
> Why not forgetting 143 at all and let all go through 993?
1: The server might not support SSL connections on port 993 (e.g. up-
imapproxy doesn't - though it does support SSL for connection to a
remote server);
2: One might be running both the client (e.g. SquirrelMail) and the
server (e.g. up-imapproxy and Courier imap) on the same machine, in
which case encrypted connections serve no useful purpose and simply
constitute unnecessary overhead.
Plus, some IMAP clients are more simple to confiure with port 143 and
STARTTLS (eudora requires "aternate port" to be set for port 993). So,
configure both.
And if you use SquirrelMail run separate Courier IMAP deamon on localhost
high port - max connection per IP address is another reson to do this.
