As is usual with technical things, it takes a few days for the true
implications of a proposal to reach my brain. I've just worked out that
I run a forwarder and why this creates a problem with SPF.
I run billericaybaptist.net, my church system, which uses a
database-generated /etc/mail/aliases to forward
alice(_at_)billericaybaptist(_dot_)net to alice(_at_)endisp(_dot_)com for about 170 users.
I have jumped onto the SPF bandwagon and published records for my
domain, but now I understand that if bob(_at_)aol(_dot_)com sends to
alice(_at_)billericaybaptist(_dot_)net, endisp will receive a message from aol.com
via my server. AOL's SPF rules will not permit this, and endisp may dump
the message.
So I need to implement some form of SRS. I already run a couple of
sendmail milters, but I understand that a milter cannot change the
envelope sender.
Any suggestions? procmail and formail? Or am I jumping the gun a bit here?
