CCS has the worst email reliability ever

If CCS was a commercial ISP, I think they'd be rated lower than Bell, or Rogers. They managed to break their email servers Saturday morning, and at least for POP users it's still broken Sunday night. Even testing via OpenSSL/Telnet, I can't get past the USER/PASS commands. Best part, they don't do tech support on weekends.

A near 48-hour outage for email would raise hell for most ISP's (I know having worked for one with way more subscribers/accounts than CCS). Even assuming that Webmail / IMAP works fine. I guess I'm just pissed that I'm stuck using @uoguelph.ca email due to university policies; I would be even more pissed if I was a post-grad alumni paying a fee for the service. I doubt there's anything I can do now, but does anyone have any suggestions about how to raise the sheer incompetence of CCS's technical abilities with a higher authority? I'm very annoyed that I just can't "change providers", so to speak.

For reference, using OpenSSL's s_client to talk POP manually:

blizzard:~/ andrew$ openssl s_client -connect mail.uoguelph.ca:995
(snip the SSL cert verbosity)
+OK POP3 ready
USER aberry
+OK
PASS my1337password
-ERR internal server error
closed
