doesn't stop greylisting
i recently upgraded to 1.6.5 and for some reason it will not stop greylisting items. i sent something over an hour ago and it still says to try again later.

the hard part is rmilter no longer shows up in any of my logs. normally when i start it i see something in my maillog that says: Oct 18 22:51:01 c6 rmilter[16865]: main: starting rmilter version 1.6.5 Oct 18 22:51:01 c6 rmilter[16865]: reload_thread: starting...
and then more rmilter log entries as things happen, now nothing.
...here is my config

What are the MTA source IP addresses for the first and subsequent attempts of sending.
with 1.7.2, greylisting does not work.

attempts were made Jan 24 11:10:39, Jan 24 11:30:51, Jan 24 11:51:50, Jan 24 12:33:50, Jan 24 13:57:51, Jan 24 16:45:51, Jan 24 22:21:54, Jan 25 09:34:01. memcached has been running since 20 Jan.
I also have greylisting trouble with google. As explained in https://support.google.com/mail/answer/180063?hl=en, google may never use the initial IP in subsequent retries.
What about using a fingerprint ( e.g md5 of subject + return-path + to + date headers ) instead of IP address as greylist key ?
Or, as suggested by google, be able to add whole domains to greylisting's whitelist ?
It seems that I've found an issue with data hash greylisting. It should be fixed by now.
Something is still not right with greylisting. I (still) use memcached, and messages get greylisted over and over again. Source IP, message ID and spamd scan result are identical, but greylisting_check_hash reports different hashes (and hence adds a new record).
rmilter 1.7.5 on Ubuntu.
I've investigated this issue and it turns out that it is related to memcached. Switching to redis should help.
