I think that is a matter of how the software is validating the SPF record. I |

have an inquiry into ASSP on this topic. |

Not sure, but I bet that is something that could be added to ASSP and may need |

You can put things like ASSP a proxy in front of mailing lists. I did that for |
| 24 |
some time. It takes some work, occasionally legit is rejected and I think some |
| 25 |
spam made it through. But it does allot and is one of the few things that can |
| 26 |
sit in front of mail servers. |
