SASL permission denied after update

[rockney]

Installed the Postfix update tonight using the Update Manager in 8.04 server. Now SMTP mail cannot be sent to the server running Postfix + Courier suite + SASL.

The mail.info log shows "postfix/smtp...warning: SASL authentication failure: cannot connect to saslauthd server: permission denied".

What happened, and how do I fix it ??

Check your permissions on /var/spool/postfix/var/run/saslauthd.

The permissions are the same as the backups:
710 with owner root and group sasl

The options in /etc/default/saslauthd have not changed:
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd"

All files in /etc/pam.d are identical to those in the backups (rsync).

It does work when email is sent from another domain, e.g. gmail.com, but does not work when sending from Thunderbird.

Thanks a lot for the help - this has me stumped.

OK, I think you need to do a

adduser postfix sasl

since postfix probably could not read the mux file.

Fabulous! That was it. Thank you!!

But - because this server was already setup and working all I did was go into /etc/passwd and change the group for the postfix user back to the sasl group (45). The Postfix update had changed it to postfix (113). I verified that by looking in the backups.

Thanks again.

No problem. That happened when you did the upgrade. It set everything back to default.
