Exclude one mailserver from SPF Check

nordpol
Hi,

Is it possible to exclude one mailserver / domain from the SPF checks? 

Background: I do have a maildomain A.com as well as a maildomain B.com. My primary Maildomain ist A.com which also have a MX entry for my own mailserver / Astaro SMTP Gateway. However I still have domain B.com which does have some forwards to my A.com domain. As both domains do have SPF entries die forwarded mails get rejected by the SMTP Proxy [:(] 

Kind Regards,

Johannes

    Hi there, 
    you should be able to create an exception to skip SPF checking.
    You need ASG v7 for that.

    hope that helps, 
    regards

    Thanks!

    This was to obvious to find it myself... sorry.

    However next question regarding the setup. My provider (domainfactory) is using more than one mailserver (mx27.ispgateway.de, mx28.ispgateway.de..) how could I use a placeholder like *.ispgateway.de? I have tried to setup a DNS Group but this doesn't work [:(].

    kind regards,
    Johannes

    Hi Johannes, 

    this is a bit more difficult, as name resolution can not be done via wildcards.

    but there might be a way that comes close to that.
    The mx servers are located within two network ranges, you can use that one instead.
    create two networks and use them in the exception:
    net 1)
    80.67.18.0/25

    net 2)
    80.67.29.0/25

    hope that helps, 
    Gert
