Hi All, I have been receiving some forged e-mails from my own domain and realised that although I have SPF records for all the domains I manage, I do not check for SPF on my mail servers. I followed https://makeityourway.de/enabling-spf-sender-policy-framework-checking-on-postfix/ to enable SPF checking. This is very similar to https://www.howtoforge.com/postfix_spf but uses the python version instead of the perl one. (I found some links recommending the python version that was replacing the perl one due to discontinued support and performance issues) After I edit the master.cf and main.cf files, and after restarting postfix, mail stops from being relayed to the inbox, but they are not rejected either. If I do a Code: postqueue -p the queue is empty... They will then get relayed to the user Inboxes after I rollback the 2 configuration files and restart postfix. On syslog I see a bunch of Code: postfix/spawn[24597]: warning: command /usr/bin/policyd-spf exit status 120 . When I run policyd-spf manually for testing this is what I get: Code: user@mail:~$ policyd-spf request=smtpd_access_policy protocol_state=RCPT protocol_name=SMTP helo_name=***.dialeto-assertivo.pt queue_id=8045F2AB23 sender=***@dialeto-assertivo.pt recipient=***@dialeo-assertivo.pt client_address=***.***.***.*** client_name=***.dialeto-assertivo.pt The reply I get is Code: action=dunno mock header field that should be ignored Any hints or guidance on what I am doing wrong? Any help appreciated... Thanks, Fernando
