Clear message

UCC will pretty much never email the email address you list when you sign up. Instead we will email [email protected], your very own UCC email address!

Much of this information is duplicated on the main website. This wiki page is however more up to date.

Forwarding your UCC email to another address

New members have the option to enter an email address to forward to upon creating their account. This will save the email address to the file .forward in your UCC home directory, typically /home/ucc/username/.

You can change the email address in this file at any time, such as by connecting to motsugo over SSH and using nano ~/.forward. All emails to your UCC email address will automatically be forwarded to the email address given in the file.

Accessing your UCC email

If you want to use your UCC email properly, and also be able to send mail from it, there are a number of options.

The settings necessary for popular email clients (Thunderbird, Outlook, etc) are listed below. For incoming mail, you can choose either POP3 (email is downloaded and kept locally) or IMAP (email is kept on the server and only cached locally).

For all mail-related authentication, use your UCC username (not email address) and password.

IMAPS (incoming)

These settings work in Thunderbird. They might not be applicable to other mail clients but you can probably figure it out.

Server Name (address): Port: 993 Connection security: SSL/TLS (not STARTTLS) Authentication method: Normal password

POP3S (incoming)

Use IMAP instead. It's much nicer.

Server name: Port: 995 Connection security: SSL/TLS (not STARTTLS) Authentication method: Normal password

SMTP (outgoing)

Server Name: Port: 465 Connection security: SSL/TLS (not STARTTLS) Authentication method: Normal password

Again, use your UCC username (not email address) and password for authentication.


UCC has one working webmail service, and another which appears to be broken.

Connect using any modern browser to and log in using your UCC username and password.

Note that RoundCube uses IMAP internally, so if you are having trouble with a normal mail client then you will likely have issues here as well. Have a look at the technical details section if this appears to be the case.

Over SSH

If you like to use SSH or are paranoid about malicious 3rd parties sniffing your email configuration, you can check email with Alpine on Motsugo (run alpine).

Technical Details has a bunch of different ports used for different things that are redirected to different servers by our firewall, Murasoi.

  • IMAP / POP3 (ports 110 and 143) and IMAPS / POP3S (ports 993 and 995) redirect to Motsugo and are served by dovecot.

  • SMTP (ports 25 and 465) redirect to Mooneye and are served by postfix

Mail is stored in your home directory. A number of different configurations are permissible and will be recognised by postfix and dovecot (so your email can be stored correctly upon arrival and later accessed by your mail client), however only one that works is documented here.

  • postfix saves mail to /var/spool/mail/username.

  • dovecot reads mail from ~/mail/INBOX

  • To make the two work properly, a good idea is to symlink ~/mail/INBOX to /var/spool/mail/username.

    • You can do this from a shell on motsugo with mkdir -p ~/mail && ln -s /var/spool/mail/$USER ~/mail/INBOX
