I found the issue.
Apparently there where two saslauthd related files in /etc/default.
/etc/default/saslauthd and /etc/default/saslauthd-postfix
I am not sure how it got there, but most likely by the previous person
working on it.
However, changing the following:
OPTIONS="-c -m /var/run/saslauthd"
To:
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd"
Finally spawned the correct socket and files in
/var/spool/postfix/var/run/saslauthd (postfix chroot).
I verified this with "systemctl status saslauthd":
├─536 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─540 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─541 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─542 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─543 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─544 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─545 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─546 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
├─547 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
└─548 /usr/sbin/saslauthd -a pam -c -m
/var/spool/postfix/var/run/saslauthd -n 10
Thank you for pointing me to the right direction!

this is a problem
/var/run/saslauthd is present - yes
/var/spool/postfix/var/run/saslauthd is present - yes
Is one dir link to another?
Do you see any files there?
It seems like both of them are "their own files" - none of them are
symlinked to anything
/var/run:
drwx--x--- 2 root sasl 140 May 10 09:17 saslauthd
/var/spool/postfix/var/run
drwxr-xr-x 2 root sasl 4096 May 10 09:10 saslauthd
So there is defintely something going on here. I guess that
/var/spool/postfix/var/run/saslauthd should be a symlink to
/var/run/saslauthd ?
Run saslauthd from the command line with the "-d" argument: it should
print the name of the socket it listens to or use
tool like "ss" to check the socket.
saslauthd -d did not print the socket in use sadly.
ss - I only found one socket being in use - /var/run/saslauthd
I wonder, should a symlink from /var/run/saslauthd to
/var/spool/postfix/var/run/saslauthd ?
Thank you
