Greylisting doesn't work correct for one domain

[Stefan Becker]

Hi,

i have one Domain with problems with greylisting. No ham mail receive the mailbox :-(

At the log i see this message:

Mar 24 20:41:39 gaius postfix/smtpd[11759]: 6595F41FF1: milter-reject: DATA from mailout05.t-online.de[194.25.134.82]: 451 4.7.1 Service unavailable - try again later; from=<user@t-online.de> to=<user@domain.tld> proto=ESMTP helo=<mailout05.t-online.de>

For the first mail, it's right. But i see this for the second shot and so on.

If i deactivate the greylisting function for this domain, mails work fine.

I chek with plesk sbin mchk the configuration, it was all fine.

Have anyone an idea?

Stefan

Hi,

Could you please paste the log output of First, second, third try?

Thanks,

Funny, now it's work. I find the entry in the Greylisting SQLite Database... I monitor this.

Thank you!
