During my attempt to repair mail functionality I did some tests which have sent some 300 mails down the gully.
When running fetchmail I always got "procmail: unknown user postmaster" errors. I therefore replaced "set postmaster "postmaster@jo-sac.ch" by "set postmaster "admin@jo-sac.ch". The latter is normally forwarded to mh@jo-sac.ch. But neither mh nor admin did receive the mails in their accounts. Where have they gone?
As I understood the installation fetchmail in multidrop mode forwards received mail to the local smtp server. But, as I finally found out, mailfront was corrupted. The service seemed to correctly start, but actually smtpfront-qmail et al. were missing from my /usr/bin! But what task was listening on port 25 during that time? Where did fetchmail send the data when there was no mailfront running?
Any information is appreciated!
