Dears,

Then i send email from any place, for example gmail.com or mail.ru I receive the following error

Jun 15 12:36:43 mail postfix-policyd: rcpt=9, greylist=new, host=94.100.176.18 (fallback1.mail.ru), from=xxx@mail.ru, to=customer@example.am, size=905

2010-06-15 12:47:27 INFO xxx@mail.ru -> customer@example.am, DUNNO

But after 20 minutes it starts to receive the mails, looks like it added that domain to allowed domain list.

Is it possible, to decrease that time, because not getting emails for 20 minutes every time is not good.

Thanks in advance

Any Ideas on the problem?
