Postfix and 9.5.1: Sending not possible / delayed when Greylisting switched on

I have the same problem.

SMTP: Postfix
SPF: Enable
DomainKeys: Enable
Greylisting: Enable

Webmail: atmail (fixed because atmail default of plesk is a **** and still with out fix smtphost in Config.php)

Error when try to send:

Solution:

Change Horde? no thanks... always fails.
Return to Qmail
Disable SPF
Disable Greylist
Domainkeys is the only thing that does not hurt ... but does not work anyway

Wow, now work like a charm !... because PLESK ALWAYS RELEASE BAD UPDATES ! (I use Plesk since 6 years ago, and never... never... never I made a upgrade without problems.

It seems to be really right!
