fetchmail won't run as the fetchmail user

[thomas kral <thomas.kral@centrum.cz>]

Dear list,

Has anyone tried to run fetchmail as the fechmail user suggested in
/usr/share/doc/fetchmail/README.Debian.gz
?

I thought that
$ adduser --system fetchmail
will do along with setting 
RUNASROOT=false in /etc/default/fetchmail
but apparently it does not, since fetchmail exits with -1 with no trace
in the log

I ended up running fetchmail as root, which is not Debian default and
recommended setting, though.

Any ideas?

Thanks in advance.

Thomas.
