I am trying to disable greylisting for @(all_subdomains).groupon.com. Using the greylisting_admin.py I disabled greylisting for '@.groupon.com', see below. However it's still being greylisted, see the iredapd.log below.

As I understand reading https://docs.iredmail.org/manage.iredapd.html and also the comments in greylisting_admin.py it should work. Am I doing something wrong?

root@genesis:/home/admin# /opt/iredapd/tools/greylisting_admin.py --list

Re: Problem disabling greylisting

Confirmed it's a bug of iRedAPD, please apply this fix and try again:

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Re: Problem disabling greylisting

Thank you. I applied the fix and it is now working, see log entry below.

I am liking your implementation of greylisting in iredapd. We used to get anywhere from 200 to 300 spam mails per day. With the combo of iredapd greylisting and amavisd blacklisting I am able to cut that down to about 10 to 20 and most of it is caught by Spamassassin.
