Hi, Our switch from Spamassasin to rspamd (with migration from old to the new system) brought some really bad problems. 1) Outgoing mail check simply blocks some outgoing, and even forwarded messages from one to another account within same our domain. Staff using Apple Mail and Thunderbird. Deleting html and links from forwarded messages sometimes helps. 2) Spam filter simply discards some messages from our key partners. Is it possible to configure server just to rewrite subject with [**SPAM**] but not discard messages? Should I just switch Policy -> Spam lover -> Yes? Or this will completely disable spam filter? Thanks in advance.
You can configure all this in the spamfilter policies. But as Rspamd is generally more accurate and produces less false positives than amavis, you should better check why the messages get discarded and fix this problem instead of trying to cure the symptoms.
I have changed these values in Policy->rspamd: Greylisting level: 5.00 SPAM tag level: 10.00 SPAM reject level: 50.00 SPAM tag method -> Subject adds ***SPAM*** Could it be enough to (at least) stop blocking forwarded messages within e-mail accounts of same our domain?
You should check why the messages get blocked (look at the log and use the Rspamd GUI), this will also tell you if the settings you use now are enough to prevent this.
