  • SPF DKIM DMARC

    From Raymar@VERT/GEO to all on Sunday, April 26, 2026 22:45:08
    Gmail is blocking me. I read the info on the Wiki and noted the "if one uses synchro.net for emailing purposes, this will not apply in that case" part.

    Solutions?

    $ host -t txt geo.synchro.net
    geo.synchro.net descriptive text "v=spf1 mx a -all"
    $ host -t mx geo.synchro.net
    geo.synchro.net has no MX record

    Do you see the problem? Your SPF record says your MX can send mail, yet you have no MX record. Like the wiki page says, this works
    "If your sending mail server is also the mail exchange (receiving mail server) for your domain", so you need to make mail.synchro.net the MX for your domain (explained on the same wiki page).

    ANother reason why we'd like DKIM and DMARC added to the Synchronet
    mail server.
