[BlueOnyx:23930] Re: SPF records for receiving email.

[Fungal Style]

Hi Michael,

Thanks for the info and clarification, I have just begun to heavily delve into SPF, DKIM, DMARC, etc as there were a few issues with "score" and not black lists sending to Hotmail and BigPond (an ISP here), and I could not find anmy reference where incoming mail checked it... 

But great reply and looking forward to it being available.

    No, at this time there is nothing in a stock BlueOnyx that checks SPF
    records.

    However, I'm currently working on transitioning 5210R to Postfix, which
    will make this a lot easier to add.

    Before someone asks about details for that:

    I currently have a 5210R that works 99% with Sendmail or Postfix and you
    can switch back and forth between either using Sendmail or Postfix via
    the GUI.

    The holdup in releasing it is adapting the AV-SPAM to Postfix, which is
    currently underway.

    From a technical point of view the dual MTA setup works like this:

    As is the GUI writes the Sendmail config files. There were almost no
    changes to that aspect.

    If the default MTA is switched from Sendmail to Postfix, then on every
    Postfix start or restart the Systemd Unit-File of Postfix will launch a
    script that parses the Sendmail configs and converts them into a format
    that Postfix understands. This is already 99% working with the only
    feature loss being support for secondary mailservers.

    The Postfix configuration can be edited by server admins at leisure as
    the GUI integration of Postfix uses the "postconf" command to edit the
    main.cf to set some basic aspects such as max message size, RBLs and such.

    Any option not used by the GUI can be edited by server admins either via
    "postconf" or by editing main.cf, which will make third party
    modifications of the Postfix config a lot easier than it is for anything
    Sendmail related.
