Qmail several errors

[FernandoA]

Hi,

Since upgrading to 9.2.3 I have problems with qmail, I got some blank emails from postmaster@mydomain.com .

After upgrading to 9.3, and now I have many more problems yet, hundreds of blank emails from postmaster, the error "Unable to get 'From:' ...", besides that many users have problems sending and receiving emails, many lost emails ...

I have Centos 5.2 64Bits

Any solution?

I had the same problem with the mails send to postmaster@<hostname>.

For me, it helped to disabled DomainKeys protection (In Plesk Settings -> Mailserver Settings).
So the error was in the DomainKeys filter: Jan 21 14:16:05 vm4 qmail-local-handlers[1682]: Unable to stat entry '/opt/psa/handlers/info/10-dd52-domainkeys-9q2xUP/executable' or it is not link: Permission denied

At one server doing this: http://kb.odin.com/en/6410 helped, but for another server this did not help and disabling the DomainKeys did.
