Email accounts is available for registred users. The addresses look like this: username (at) blinkenshell.org
The accounts have 10 MB quota and are accessed via Secure IMAP (TCP 993) or HTTPS enabled webmail (Squirrelmail).
SMTP access is available, but you have to log in to be able to send mail. It's the same username/password as IMAP/etc.
Ask Independence if you want an email account. It's an optional add-on service and not enabled by default.
If you want to, you can also get a forward to another address (username (at) blinkenshell.org -> yourname (at) gmail.com)
