A RSpamD hook would make complete sense!

Though the greylisting would need=
 to be backed with a persistance solution (redis ?) so implementing it to p=
lug Rspamd greylisting to James' future greylisting is quite some work=2E

(contribution welcomed indeed)

 If that would be too much, one could also use another rspamd instance that=
 only has the ratelimiting and greylisting modules and would be way faster=
=2E
The design allows the mailet to override the default rspamd instance=2E=


We should adopt the same principle in a future RSpamD kook=2E

Also we'd =
likely benefit from:
=C2=A0- SMTP hooks for james rate limiting
=C2=A0- An =
analysis of what makes RSpamD rate limiting more advanced than James' one (=
I'm curious!)

nger <felix=2Eauringer@giz=2Eberlin>Hey Benoit,

You're completely right, t=
he soft reject action is worthless as a mailet=2E
There is already an exper=
imental SpamAssassin SMTP hook=2E Do you think a Rspamd hook might also mak=
e sense?
In addition to greylisting, Rspamd also has a more advanced rate l=
imiting mechanism than James=2E
The Rspamd tests always take less than 2s w=
ith my current configuration which would probably not hit any timeouts=2E I=
f that would be too much, one could also use another rspamd instance that o=
nly has the ratelimiting and greylisting modules and would be way faster=2E=


Best regards,
Felix
