Hello, I've been using Postfix for many years without significant problems.
However, due to a forced change in ISP, I can no longer have a correct PTR record pointing to mail.linetec.nl, causing a lot of ISP's to reject e-mail from my server.
Reverse DNS for my IP address now points to the ISP's generic name 77-172-184-9.fixed.kpn.net
Could I solve this by setting smtp_helo_name in main.cf to 77-172-184-9.fixed.kpn.net ? Or is this a bad idea?
Thanks for any suggestions, Best regards, Richard
