12 Mail /etc/init.d/postfix restart If the Univention Configuration Registry variable mail/archivefolder is set to an e-mail address, Post- fix sends a blind carbon copy of all incoming and outgoing e-mails to this address. This results in an archiving of all e-mails. As standard the variable is not set. If there is no mailbox for this address, one will be created automatically. The Univention Configuration Registry variable mail/postfix/dnslookups (yes/no) is used to configure the DNS resolution of hostnames for the delivery via SMTP and LMTP. If the variable is set to no the resolution occurs over the standard system routine, which typically also enters entries in the /etc/hosts file. In a number of error situations (e.g., for non-existent users) the result may lead to a mail bounce, i.e., the mail cannot be delivered and is returned to the sender. When the Univention Configuration Registry variable mail/postfix/softbounce is set to yes mails are never returned after a bounce, but instead are held in the queue. This setting is particularly useful during configuration work on the mail server. Mail routing is usually effected via MX records saved in DNS. In special cases - for example, the operation of a tunnel between two servers which cannot be resolved via DNS - it may be necessary to configure a manual transport route. Thus can be added to the file /etc/postfix/transport using the Univention Configuration Registry variable mail/maps/transport/IDENTIFIER. An example: mail/maps/transport/1="somedomain.org smtp:[mail.somedomain.com]" Sometimes it is necessary to rewrite e-mail addresses, for example when new e-mail addresses are added during a restructuring operation. This can be effected using canonical mappings. The Univen- tion Configuration Registry variable mail/maps/canonical/sender/enable can be used to rewrite on the server side either using the file /etc/postfix/canonical_sender (file) or via access to the LDAP (ldap). The settings for reformulating recipient addresses are performed over Univention Configu- ration Registry variable mail/maps/canonical/recipient/enable. If it is configured to file, the file /etc/postfix/canonical_recipient is read out; access to the LDAP (ldap) is also possible here. Univention Configuration Registry variable mail/maps/canonical/sender/classes can be configured to specify which address information should be converted. The options available for selection are envelope_sender and/or header_sender. If the package univention-mail-cyrus is installed, SMTP authentication is available as standard. If univention-mail-postfix is intended to be operated independently, the configuration for the authentication service saslauthd must be adjusted manually and the following entry entered in the /etc/default/saslauthd file: START=yes Postfix then uses the saslauthd for the authentication. 12.3.2 IMAP/POP3 server (Cyrus) Cyrus offers IMAP and POP services preconfigured using the univention-mail-cyrus package. The authentication is performed using the primary e-mail address. That means that the e-mail address should be 258
12.3 Setting up the mail server entered as the user name in mail clients for POP or IMAP access. Configuration examples for Kontact and Outlook can be found at the end of this Chapter. The services can be deactivated separately with Univention Configuration Registry. If no access should be available via POP, Univention Configuration Registry variable mail/cyrus/pop must be set to no. The same applies to IMAP and Univention Configuration Registry variable mail/cyrus/imap. As soon as a user in the LDAP directory is assigned a primary e-mail address, a listener module creates a mailbox on the Cyrus server under /var/spool/cyrus/mail/domain in the subdirectory //
