Re: AW: Greylist-like support

2018-04-07 Thread Aham Brahmasmi 
>From my limited understanding reading the GitHub issues,
OpenSMTPD is being modified in a way that will help resolve certain
problems that OpenSMTPD was facing. [1][2][3]

Monsieur Gilles Chehade has tweeted that he has a version with the
newer configuration file format. [4]

On this list, I have requested for some information on the newer version
this week. Specifically, the distribution mechanism of the snapshots,
the suitability for production and the feasibility to use the
OpenSMTPD-extras with the newer version.

For an overview, please refer to the excellent talk titled
"OpenSMTPD, current state of affairs" by Monsieur Gilles Chehade. [5][6]

I've been pondering the exact same thing the last few days. I've been
looking at rspamd, but I'm not keen on switching, since I just migrated
from an old QMail system and am using amavisd-new/spamassassin now. A
little disappointed that amavisd-new doesn't have greylisting built in.
 
Good luck,
Reio

I've been pondering the exact same thing the last few days. I've been

looking at rspamd, but I'm not keen on switching, since I just migrated

from an old QMail system and am using amavisd-new/spamassassin now. A

little disappointed that amavisd-new doesn't have greylisting built in.

Good luck,
