The way we're going to do it here is:
pobox.com TXT "v=spf1 a mx etc ... redirect=%{l}._spf.pobox.com"
then:
mengwong._spf.pobox.com TXT "v=spf1 a:dumbo.pobox.com -all"
user1._spf.pobox.com TXT "v=spf1 include:earthlink.net ?all"
user2._spf.pobox.com TXT "v=spf1 include:verizon.net ?all"
etc.
Thanks for the quick reply!! I'll archive the above for future reference!
6. Outsource the thing to a forwarding service that does
these things for a living :)
Yeah! (Unfortunately, I'm hosting the club for free out of my good graces
... because of a commitment my wife made in my behalf a number of years
ago. The promotion of domestic tranquility eliminates this option ...
[sigh])
7. When MUAs let you configure return-path differently from
"From:" header address, use the club address in the
"From:" and the ISP-given email address in the
return-path.
Also a good idea. Thanks!
