[SOLVED] greylisting

[al10]

hi,

today at 11:43 someone tried to send me a mail, but it didn't go through. turns out it was greylisted:
Apr 20 11:43:17 smtp postfix/smtpd[2749]: connect from mx14lb.world4you.com[81.19.149.124] Apr 20 11:43:17 smtp postfix/smtpd[2749]: NOQUEUE: reject: RCPT from mx14lb.world4you.com[81.19.149.124]: 450 4.7.1 <receiver@receiver.com>: Recipient address rejected: Service is unavailable (try later); from=<sender@sender.com> to=<receiver@receiver.com> proto=ESMTP helo=<mx14lb.world4you.com> Apr 20 11:43:17 smtp postfix/smtpd[2749]: disconnect from mx14lb.world4you.com[81.19.149.124] ehlo=2 starttls=1 mail=1 rcpt=0/1 bdat=0/1 quit=1 commands=5/7

he then tried to send it again, but this time it went through without issues.
a few hours later the greylisted mail arrived as well.

this seems a little inconsistent to me, is this intended behaviour or is there something wrong with my config?

thanks for reading.

i think, its ok

after the first reject, the pmg waits for the next try to deliver the mail - the second mail was the "second try" for pmg und it would delivered and the Server was listed for next time

The timing depends on the sending mail server's queue retry time I believe and not anything within PMG's configs.
