Problems with receiving emails

If everything is working, but you can't see the incoming emails, check if the ~otrs/bin/PostMaster.pl program is working correctly. Pipe an example email through the PorstMaster.pl. There are two example emails in the default OpenTRS package (~otrs/doc/test-email-*.box or /usr/share/doc/packages/otrs/test-email-*.box).

Example:
shell:~ # cat /usr/share/doc/packages/otrs/test-email-1.box | /opt/OpenTRS/bin/PostMaster.pl 
shell:~ #
May there is an error message, then you have to fix it. If not and you see this email in the postmaster queue, the procmail program isn't configured with your MTA (check the MTA log file, e. .g /var/log/mail) or the $HOME of the otrs user isn't correct (check $HOME and $HOME/.procmailrc).
