Error in mail.log with some emails

Hi I finished a migration of a webserver (mailpart) with the migration tool to a dedicated mailserver.

Now some of my email will go through and some will get an error and gets queued up.
Error in postqueue:
local data error while talking to ((RECIEVING MAILSERVER))

Corresonding error in mail.log
warning: hash:/etc/postfix/sasl_passwd is unavailable. open database /etc/postfix/sasl_passwd.db: No such file
warning: hash:/etc/postfix/sasl_passwd lookup error for ">>FICTIONAL EMAILADRESS<<"
warning: D659860F80: smtp_sasl_password_maps lookup error

Checking if the file is not there and its not...

I tried to update ispconfig and reconfigure the services but unfortunatly it didnt help.

 

I have no idea why i had this error (not my first perfect server install), but my solution was:

Code:

touch /etc/postfix/sasl_passwd

Code:

postmap /etc/postfix/sasl_passwd

restart postfix
force the resend of the queue

Code:

postqueue -f

 

Ubuntu 20.04

You are correct. I used the nightly.

What i also noticed is that the postfix install doesn't start itself. I have to manually start it by running:

Code:

dpkg-reconfigure postfix

 

awesome!
