Blocked MTA-BLOCKED {TempFailedInbound} After Upgrade of Ubuntu to 22.04

After an upgrade of my server 2 I cannot send email on it. In server 1, it still works fine.
Here's the error message when I run this command
# service amavis status

Code:

In Ubuntu 20.04, I don't remember I setup anything in Amavis. Now, in Ubuntu 22.04, I think Amavis is the one causing this problem. But I don't know where to fix it.
Any help is highly appreciated.
Thanks

 

Your postfix is not working correctly.

Check the status of postfix and have a look around the logs for "error" and "fatal" messages.

 

Thanks for the reply. Here's the error message in /var/log/mail. Err:

Code:

Nov 29 21:47:10 server2 postfix/smtps/smtpd[100743]: fatal: no SASL authentication mechanisms
Nov 29 21:47:11 server2 postfix/smtpd[102045]: fatal: no SASL authentication mechanisms

I'm using sendinblue to send email. Don't know what I'm missing.

 

Here's an additional error messages:

Code:

Nov 29 21:54:49 server2 postfix/smtpd[107134]: warning: SASL: Connect to private/auth failed: Connection refused
Nov 29 21:54:49 server2 postfix/smtpd[107134]: fatal: no SASL authentication mechanisms

Nov 29 21:54:50 server2 postfix/master[106512]: warning: process /usr/lib/postfix/sbin/smtpd pid 107132 exit status 1

It says bad command startup -- throttling.

 

I have already restart dovecot, as well as amavis and postfix. Anything I'm still missing?

 

Oh, I did not. Let me run it and update you as soon as I finished updating it.

 

@till
The error is gone. And it seems it is sending correctly. Except that the email did not arrive on my mailbox.
Please see log below:

When I send a test mail to my gmail account. The mail delivered correctly. But it does not deliver on my email hosted on this server.

 

I think the mail did not synchronize on my database. I am sending this email on my server 2.
How do I know that the mail synchronize on server 1? Where can I find this in the database?

 

Thanks a lot. At last I fixed it!
