Do I have to create DKIM record for MX server?

    I used to set up ISPConfig3 on a single server with a domain name for everything. It worked very well.

    On my new ISPConfig3 setup, my ISPConfig3 host has a separate host name which hosts several web domains and email domains.

    For my first email domain, I created its DKIM, SPF, DMARC records. It can receive incoming 3rd party emails but its outgoing emails are rejected by 3rd party email servers. So how do I correct it?

    Here is a sample of error log recorded by postfix:

    Sounds more like your ISP/host blocks port 25 connections and unrelated to dkim.

    Yes, I disable my CSF firewall and the emails pass. I must have configured something wrong.

    You are the de facto ISPconfig expert! :cool:

    I can tell you. Those on stuckoverflow are mostly wrong and misleading. :D
