Hi guys, firstly - I have to admit that I didn't do any search because quite honestly I don't know what to look for - no error logs no nothing just spam keeps coming in :/ What I want - I want to reduce spam as currently I get a lot of awful spams from "myself" ie. From: firstname.lastname@example.org To: email@example.com Subject: Re: Salary [$1000 /week] (I suppose you get these as well) What I did: I tried to follow the instructions here: https://www.howtoforge.com/hardening-postfix-for-ispconfig-3 I added the TXT record to my NS hosting provider (Cloudflare): Code: v=spf1 ip4:185.X.XX.XX -all Where the 185.X.XX.XX is my VPS IP address used for email hosting. I followed the part in the article: "SPF Check For Postfix (Debian And Ubuntu)" apt-get install postfix-policyd-spf-python + did the edits necessary + /etc/init.d/postfix reload and the awful spams from "myself" are still coming. Any Ideas? Thanks!
