Greylisting (non-rspamd)

[Indominus]

I know Greylisting works when using rspamd, but we're still using spamassassin and prefer to keep using that.
is there any out-of-the-box method to enabling greylisting (greylistd?) with the 'default' DA setup?

I am seeing some older forum topics with instructions, but they are not really recent and instructions don't seem to work.

Before you spend too much time on it, just a heads up, unless you have a unique scenario where you can confirm that it helps with anything, you might consider that it doesn't. Several years ago, when I did it by default, I found that its primary function was to frustrate users who were receiving confirmation codes used by various login systems (Steam, for example, though even some banks and many other websites do the same). It has been a long time since I've seen greylisting reduce spam by any noteworthy amount. I am of the opinion that it is a relic, an example of something that helped in the past.

Hi mxroute,

Thank you for your reply.
Where I normally run custom setups of mailservers I now have multiple customers using DirectAdmin as part of their mail setup.
Of course when greylisting you build some sort of whitelist/reputation list; in effect I do not have had customers complain about delays in their mail after the first few days.
That said, you may be right about it being a relic and maybe have to look out for some other tweaks to prevent incoming spam.

I believe I came across some of your posts, am I right that you are migrating from rspamd back to spamassassin?

Indeed. I continually had to explain to users that the SpamAssassin configuration page in DirectAdmin would not work as expected because their configurations were being parsed and turned into Rspamd includes instead. Overall I didn't find that Rspamd produced enough of a difference over SpamAssassin and that it reasonably harmed users' ability to customize their configuration at the user level. The only real benefit to Rspamd, in the end, was that it's more lightweight on resources.
