Question plesk_saslauthd: No such file or directory

[Borsal]

Hello Forum,

my mail.warn says:

Jul 21 00:15:55 master[1707]: fatal: master_spawn: exec /usr/lib/postfix/sbin/plesk_saslauthd: No such file or directory
Jul 21 00:15:56 postfix/master[1387]: warning: process /usr/lib/postfix/sbin/plesk_saslauthd pid 1707 exit status 1
Jul 21 00:15:56 postfix/master[1387]: warning: /usr/lib/postfix/sbin/plesk_saslauthd: bad command startup -- throttling
Jul 21 00:16:56 master[6980]: fatal: master_spawn: exec /usr/lib/postfix/sbin/plesk_saslauthd: No such file or directory
Jul 21 00:16:57 postfix/master[1387]: warning: process /usr/lib/postfix/sbin/plesk_saslauthd pid 6980 exit status 1
Jul 21 00:16:57 postfix/master[1387]: warning: /usr/lib/postfix/sbin/plesk_saslauthd: bad command startup -- throttling

From reading this, the path to the saslauthd is clearly wrong, but i can´t figure out, what the correct path is.

My master.cf: master.cf - Pastebin.com

My main.cf: main.cf - Pastebin.com

i think the problem is since the server was upgraded to debian 9 and the mail.info is saying lately:

postfix[1028]: Postfix is running with backwards-compatible default settings


i hope someone can help me.


Greets,

Borsal

This file is a part of plesk-mail-pc-driver package:

# ls -la /usr/lib/postfix/plesk_saslauthd

# dpkg -S /usr/lib/postfix/plesk_saslauthd

Please make sure that this package is correctly installed on your server.

It still says:

Jul 21 07:41:08 master[23011]: fatal: master_spawn: exec /usr/lib/postfix/sbin/plesk_saslauthd: No such file or directory
Jul 21 07:41:09 postfix/master[21882]: warning: process /usr/lib/postfix/sbin/plesk_saslauthd pid 23011 exit status 1
Jul 21 07:41:09 postfix/master[21882]: warning: /usr/lib/postfix/sbin/plesk_saslauthd: bad command startup -- throttling

but the file is there:

# ls -la /usr/lib/postfix/plesk_saslauthd
-r-xr-x--- 1 root root 98312 Mar 17 10:22 /usr/lib/postfix/plesk_saslauthd

# dpkg -S /usr/lib/postfix/plesk_saslauthd
