Hi puck
The e-smith server features a great email server (based on Qmail) that supports POP3, SMTP and IMAP protocols.
When you create a user account, that action also automatically creates an email account for that user (user_account_name@yourdomainname).
The manual has simple detailed instructions, and the v3.1 manual is available for download (v4.0 will be up on Monday) However, in short:
To create a user account, you access the e-smith manager at
http://www.e-smith.yourdomainname.com/e-smith-manager(for version 3.1 it's just:
www.yourdomain.com/e-smith-manager)
Go to user accounts, and follow the instructions from there to create a user account.
Yourdomainname is the domain name that you entered in the configuration wizard.
Don't forget that you have to ask your ISP to publish MX records for your domain so that mail addressed to your domain name will be routed to your e-smith server.
Hope this helps.
