How many rejects for greylisting?
Hi! I'm not new to greylisting, but at work the server reject the mx just once and the second times it is allowed to deliver: at home I'm trying to understand why or when a sender is rejected more than once from postfix greylisting. This is an example:
Feb 1 10:56:33 reveng /usr/libexec/postfix/greylist.pl[48684]: Temporary message rejection to: <recipient@email.xxx> from: <sender@email.xxx> sent from: [xx.125.83.43] for: 60 seconds due to greylisting
Feb 1 11:04:18 reveng /usr/libexec/postfix/greylist.pl[48747]: Temporary message rejection to: <recipient@email.xxx> from: <sender@email.xxx> sent from: [xx.125.83.47] for: 60 seconds due to greylisting
Feb 1 11:18:18 reveng /usr/libexec/postfix/greylist.pl[48827]: Temporary message rejection to: <recipient@email.xxx> from: <sender@email.xxx> sent from: [xx.85.215.179] for: 60 seconds due to greylisting
In example, the e-mail the server received last night at 1:00, i received at 6:40 in the morning... I suppose that is because it "doesn't understand" that different IP doesn't mean different mx server (clustering). Anyone know how to configure it correctly? There is something at GUI level I didn't configured, or have I to edit manually smtpd_recipient_restrictions in main.cf?
Thanks in advance,
