Hi, I am a systemadministrator in charge of security and actively maintaining our email servers (postfix/exim). Are we talking about setting it up for the incoming emails to be checked or for your postfix server to be checked by other servers. In both case both options should be enabled. Could you precise what has already been made? Do you use amavisd? Looking forward to work with you

hello, is SPF necessary for both outgoing and incoming messages? As for the outgoing ones it's really a 5 minutes task: just the time it takes to add a new TXT record in your domain name server. Instead, SPF checks on incoming messages requires configuring a policy daemon: it's not as simple but for sure it cant take more than 1 day. Dont you need to introduce also DKIM and DMARC?
