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!
