A mail server can be installed from the Univention App Center with the application Mail server. Alternatively, the software package univention-mail-server can be installed. Additional information can be found in Installation of further software. A mail server can be installed on all server system roles. The use of a UCS Directory Node is recommended because of frequent LDAP accesses.
The runtime data of the Dovecot server are stored in the
/var/spool/dovecot/ directory. If this directory is on a NFS share,
please read Mail storage on NFS.
