The package univention-fetchmail adds additional attributes to the users/user object that hold information from where the fetchmail service should fetch new mails and deliver it to the local mailbox. This is used to fetch mail e.g. from your provider if mail is not delivered directly to your mail server.

Usually a remote server is specified. In the test script it should be sufficient to use a different IMAP/POP3 mailbox on the local system. If is possible that fetchmail/postfix rejects mails because a possible mail loop is detected. In that case please try to use the NetworkLoop.

Scenario:
new mail ===> mailbox of user A ==> fetchmail ==> mailbox of user B
- the test should save a copy of /etc/fetchmailrc before any LDAP changes are 
  performed
- create 2 users A and B
  - for user B the fetchmail settings have to be set: the mails shall be fetched 
    from mailbox A on $FQDN
- the default /etc/fetchmailrc contains an interval of 1200 seconds. This 
  interval should be reduced to e.g. 10 seconds by the script (load whole file 
  and replace statement accordingly).
- restart fetchmail
- send mail with token to user A and wait until the token appears in mailbox B


Please also check the additional fetchmail options:
- keep mails on server (is mailbox A empty after token appears in mailbox B?)
- use IMAP or POP3: cyrus and dovecot support both and can be deactivated 
  seperately (just to be sure, that the correct protocol is used)
- encrypted connection (by default please use always an encrypted connection; 
  the common usecase)
