Postfix AUTH problems

[MajidC]

I have Plesk Panel on Ubuntu server 10.04.
Everything was set up and working perfectly. Only change I made to the mail configuration was to allow submission port 587.
Everything was still working: imap, smtp etc.

But yesterday, I think after an update, I noticed I can't send mails. So, now there is no way to make it work.

These are messages I get in /var/log/mail.info:

postfix/smtpd[9523]: warning: SASL authentication failure: no secret in database
postfix/smtpd[9523]: warning: SASL DIGEST-MD5 authentication failed: One time use of a plaintext password will enable requested mechanism for user
postfix/smtpd[9523]: disconnect...

There are many tutorials to make postfix work with dovecot, but I'm afraid to install dovecot, because when I run apt-get install dovecot-imapd, it says that many psa-* features will be removed.

Any help is welcome.

Here are my main.cf:

I am no expert at this, and this is becoming very annoying now. It was working perfectly, and now it won't send mails...

Thanks in advance.

It didn't help. I get these messages now:

I managed to repair it by reinstalling.

Eventually, I found the link "Updates and Upgrades" in "Server" section of the Plesk Panel. There I went to "Add component", and installed `QMail` as SMPT, so it automatically removed `Postfix`, and again installed `Postfix`, so `QMail` is automatically removed.

This changed Postfix's settings to the default. Then I just enabled submission port again, and left everything at the default, like the first time.

Now it works again.
