[Pkg-exim4-users] cannot connect to /var/run/saslauthd/mux

[Nikolaus Rath]

Hello,

I have added Debian-exim to the sasl group:

[0] nelarikon:/etc/exim4/conf.d# groups Debian-exim 
Debian-exim : Debian-exim sasl

The permissions for /var/run/saslauthd seem also correct:

[0] nelarikon:/etc/exim4/conf.d# dir /var/run/saslauthd/ 
total 12K
drwx--x---   2 root sasl 4.0K Apr  3 09:53 .
drwxr-xr-x  15 root root 4.0K Apr  3 09:19 ..
srwxrwxrwx   1 root root    0 Apr  3 09:53 mux
-rw-------   1 root root    0 Apr  3 09:53 mux.accept
-rw-------   1 root root    6 Apr  3 09:53 saslauthd.pid

However, exim still produces this error:

[0] nelarikon:~# exim4 -d+auth -bh 127.0.0.1
Exim version 4.50 uid=0 gid=0 pid=22336 D=fbb95cfd

When I change the permissions to "chmod 711 /var/run/saslauthd",
everything works fine. So it seems that exim is not really running as
user Debian-exim. Is there any way I can check this? (Yes, I restarted
after adding Debian-exim to the sasl group).

Or am I missing something very obvious?

Thanks in advance,
