Postfix triial-rewrite warning

Postfix trivial-rewrite warning (mydestination & virtual_alias_domains)

Hi,

I recently updated my Panel to the latest 11.5 version, after that I also switched from qmail to Postfix. Everything works fine, excpet some Postfix warnings which occur about 15 times a day. I don't know how to reproduce the error, it seems pretty random but comes right after some smtpd connections.
From /usr/local/psa/var/maillog:

Jul 11 08:01:46 plesk postfix/smtpd[24362]: connect from st11p01mm-asmtpout005.mac.com[17.172.204.240]
Jul 11 08:01:46 plesk postfix/trivial-rewrite[24124]: warning: do not list domain plesk.company.com in BOTH mydestination and virtual_alias_domains

From postconf:

mydestination = localhost.$mydomain, localhost, localhost.localdomain
mydomain = company.com
myhostname = plesk.company.com

Machine hostname: plesk.company.com

I did not change any postfix-configurations, i also don't have the domain "plesk.company.com" created in Plesk.
However, if I do
postmap -s virtual | grep plesk\.company\.com
I get this output:

postmaster@plesk.company.com   postmaster@localhost.localdomain
root@plesk.company.com root@localhost.localdomain
drweb@plesk.company.com        drweb@localhost.localdomain
kluser@plesk.company.com       kluser@localhost.localdomain
mailer-daemon@plesk.company.com        mailer-daemon@localhost.localdomain
anonymous@plesk.company.com    anonymous@localhost.localdomain
plesk.company.com      1

Any ideas how to solve this? I never changed the hostname or did any custom mail configurations. Also emails still arrive, even if after the warning. OS is CentOS 6.4

can at least someone tell me the normal Postfix configuration, especially the configuration of machine-hostname against postfix' mydestination, mydomain and myhostname?

I have similar configuration (w.r.t. bits you posted) and no such warnings. Please also note that this warning is harmless.

I have exactly the same set-up as Manuel (recent Plesk upgrade, change from qmail to postfix) and I get the same warnings. It started when I couldn't send out a newsletter with PHP mail() because "apache@localhost.myservername" was not considered as a valid email address for sending. I resolved this bu going into etc/postfix/main.cf and appending

smtp_generic_maps = hash:/etc/postfix/generic

and then adding in etc/postfix/generic

apache@localhost.myservername postmaster@mydomain.com

However in addition to these trivial-rewrite warnings (apparently harmless), I am now seeing my IMAP service shutting down once or twice a day.
qmail was much better but apparently it has incompatibilities with Plesk 11.5
