Hi Timo,

now I have:

service auth { executable = /usr/bin/strace -D -o /tmp/auth.strace -s 100 /usr/lib/dovecot/auth group = vmail user = vmail inet_listener auth { port = 12345 listen = 10.0.0.80 fd00::10:10:0:0:80 } }

The problem is, no strace file will be written?

ls -l /tmp/auth.strace

ls: cannot access '/tmp/auth.strace': No such file or directory

With systemd the /tmp directory is actually under /tmp/systemd-something/. Try find /tmp -name auth.strace or use some other directory than /tmp.
