Greylisting mystery

Some (considerable) time ago, I was experimenting with greylisting. At the time I determined that it wasn't a good fit for my circumstances, and disabled it - or so I thought.

Today I was looking for something else and happened to click on Greylisting in the Admin console. Lo and behold, Greylisting is enabled. I thought, cool, it's working so transparently, I didn't even know it was on. But then I got to thinking, that can't be.

I searched over a year's worth of logs, and there' s not a single instance of "SENT: 451" in any of them. (I always have SMTP logging on.) I fired up MSSQL and issued

Code: Select all

select count(*) from hm_greylisting_triplets;
and it came up with zero.

Greylisting settings are:

Code: Select all

Minutes to defer delivery attempts: 4
Days before removing unused records: 2
Days before removing used records: 65
Bypass on SPF and Bypass on A or MX record are both checked (but I know I get plenty of incoming connects that fail SPF and don't have DNS records).

The greylist's whitelist appears to be the default config; there's not like a universal wildcard entry that would bypass everything.

I've checked the IP ranges, and they have the Anti-Spam check box checked.

Is there some other setting somewhere that overrides greylisting?

Yes. If you look in the DOMAIN-ADVANCED tab of your actual domain, you will see you also have to enable 'greylisting' against the individual domain. If it isnt enabled there then the greylisting function will not apply to that particular domain.

Mind you... if you have been living without greylisting (as it seems you have been), and it hasnt been a problem in doing so, then thats a result. :mrgreen:

A ha - Makes sense.

Might be worth a mention in the docs at https://www.hmailserver.com/documentati ... reylisting ... I was all over the docs trying to figure this out.
