    It would be great if greylisting could be configured to only match on the first three octets and not all four of an IPv4 address (similar for IPv6) - there are large enterprises out there running several MX hosts on same subnet that seem to share one queue. It seems to be pretty common to have their mails retried up to 8 to 12 times for delivery (each MX will try once) which results in delays of half a day. I was happy to hear that greylisting is possible with Plesk however I still prefer my old solution that is capable of allowing same subnet senders.

    Alternatively, a range value (-/+) of IP address "neighbours" could be helpful, if someone feels that 255 hosts will be too much to accept on the second try.

    Hi!

    Thank you for sharing the idea!
    Please, share it at Plesk User Voice.
    The top-ranked suggestions are likely to be included in the next versions of Plesk.

    It is a good idea to get rid of the "static" blacklist rule, many hosting centers use this word in rev dns.
