[lug] SPF filtering on outbound recipient

[Jed S. Baer]

Hi Folks.

Any SPF experts here? I've been doing some web searching, but not finding
directly useful information.

Problem: Jefferson County Library has declared my e-mail address invalid,
due to lack of an SPF record. They're filtering outbound mail they're
generating, using the recipient mail domain. This seems, at first blush,
odd, since SPF is "sender" permission framework, rather than "recipient"
permission framework.

The TLD cotse.net does have an SPF record, but apparently, that doesn't
help. Maybe it should?

Is it a mis-application of SPF to filter outbound mail in this fashion?

Thanks,
jed
