I reveive many complaints that mails could not be sent through my server anymore (recipient on my server or forwarding via my server) another message is I'm using rspamd. This is what I found in mail.log Any idea? Do I have to disable spamhaus?
I've checked postfix main.cf There I found According to https://docs.spamhaus.com/datasets/docs/source/40-real-world-usage/MTAs/020-Postfix.html the blocking should be done in rspamd and not on smtp-level. Is that right? So should I remove the reject_rbl_client entries above and configure it according https://github.com/spamhaus/rspamd-dqs ?
Is this an ISPConfig system? If yes, go to System > server config > mail, remove zen.spamhaus.org from the RBL field, and press save. Spamhaus has been causing lots of issues lately, so ISPConfig has not used it anymore for some time.
I know it's not the same issue, but is there any news on implementing SRS? Most of my clients are using their domains just for mail forwarding and they get more and more errors...
You can use SRS on ISPConfig, it's just not set up by default. Google e.g. for "postfix postsrsd". You can also find threads about that here in the forum.
Yes, I found this: https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/2551 (with "Till Brehm changed milestone to %3.2.13 vor 3 Monaten") and this https://share.rb-hosting.de/s/EdbfgQxwTX3AqMN But I was waiting if it would be included and not that I break something with a new config --> would you recommend to wait for 3.2.13 or can I continue implementing it?
I can't give you a definite date when this will be included as it has not been widely tested and verified yet. So if you need it now, then you might want to try if it works. Likely, you have to redo this on updates though until it made its way into the main code.
