[pfx] Re: Do you reject DMARC failures?
In POSTSCREEN i use 12 blocklists and whitelists. each is given a particular score based on a custom ML algorithm. The scores get adjusted everyday based on the performance of the RBLs. I don’t reject based on SPF, DMARC, or DKIM. However i do have spam detection powered by RSPAMD, which takes into account SPF,DKIM,DMARC and host of other stuff. right now experimenting with LLMs as tool to detect SPAM apart from the standard baye’s.

Funny, since multiple people in the past recommended rejecting on spamminess, not on the results of single DNSBL listing. I use only two DNSBLs that - at least for me - seem to give almost no false positives - bl.spamcop.net and zen.spamhaus.org. In the past I used three - instead of zen.spamhaus.org I was using dul.dnsbl.sorbs.net and sbl-xbl.spamhaus.org. But because sorbs.net went down, and zen.spamhaus.org seems to effectively combine these two, I changed it. Of course I always have the option to manually override DNSBL listing in my manual access list, but I don't remember when I last had to use it. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

Fr LLM based detection rspamd has a new a new GPT Plugin they introduced with version 3.9 https://rspamd.com/doc/modules/gpt.html https://rspamd.com/misc/2024/07/03/gpt.html Currently it’s based on OpenAI apis. but can be adapted for local LLMs or any LLM offering OpenAI type APIs.

And Message-Id SHOULD not be folded, even if over 78 bytes long. I think it is fine for Postfix to treat folded Message-IDs as malformed. Interesting. I can see the following from certain microsoft noreply mail ids breaking line > 998 bytes with SPACE What is this? It doesn’t happen with outlook personal mails.

Thats all fine. But when clamav is done, rspamd scans it again. you are using amavis as content filter with clamav you are probably using rspamd with clamav module as a milter so clamav scans your mail twice. what is the problem? cheers chandan ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
