After a while i was not able to send emails again.
I used the add or remove components tool in plesk to remove postfix and installed qmail.
Then i did it the other way around. I guess like
@fhe did it.
After this i was able to send emails again.
Heres's what i found out:
1. No Change here:
cat /etc/postfix/sasl/smtpd.conf output:
pwcheck_method: auxprop saslauthd
auxprop_plugin: plesk
saslauthd_path: /private/plesk_saslauthd
mech_list: DIGEST-MD5 CRAM-MD5 PLAIN LOGIN
sql_engine: intentionally disabled
log_level: 4
2. No change here:
stat /var/spool/postfix/plesk/passwd.db output:

3. This Line changed in the file /etc/postfix/master.cf from:
smtp inet n - - - - smtpd
to
smtp inet n - y - - smtpd
I think this Solution is Similar to
@Andri
But it's not the same.
Hope it keeps working now. And hope it finally helps you all.
