UCS optionally makes mail services available which can be accessed by both mail clients and webmail applications. The mail server component available in the Univention App Center can be installed with just a few clicks of the mouse and sets up Postfix and Dovecot so that they are ready for use. Mail services replicate the function of a complete mail server (SMTP, POP, IMAP), making it possible to send and receive e-mails via UCS and forward in-house e-mails.
The administration, such as the assignment of e-mail addresses or aliases to users, is performed centrally via the UCS management system as usual.
In addition, the Univention App Center also offers a whole range of collaboration and groupware solutions for UCS.
