Hello, I’m using pf greylisting on OpenBSD. More and more emails from Google are delayed and few are not delivered at all.
This https://support.google.com/mail/answer/180063 Google article suggest to replace greylisting with SPF or DKIM. What is your anti SPAM strategy please? Are available SPF and DKIM configurations examples for OpenSMTPD? Thak you for your recommendations. Best regards, Jiri -- Jiří Navrátil, http://kouc.navratil.cz, +420 222 767 131
