5) /etc/aliases contains
addr: "|/usr/sbin/sendmail -oi newaddress(_at_)example(_dot_)com"
to send the msg with a new envelope-from; bounces will go back to the
postmaster at your domain. In this setup, I think this is appropriate,
since generally the failure case is that the forward address has changed
and the aliases need to be updated.
An excellent intermediate solution. Many thanks for that: I have now
implemented it. In case anyone is interested, my current setup is:
1) alice(_at_)aol(_dot_)com sends to bob(_at_)billericaybaptist(_dot_)net
2) bob(_at_)billericaybaptist(_dot_)net is in the sendmail virtusertable, and
resolves to the local user "bbc-bob".
3) /etc/aliases maps bbc-bob to "|sendmail -f
postmaster(_at_)billericaybaptist(_dot_)net -oi bob(_at_)hotmail(_dot_)com"
4) Bob gets his message from Alice, with the envelope sender set to my
postmaster account.
Now, even if HotMail block on SPF failure, Alice's message gets through.
This is clearly not ideal for large remailers, as they would receive all
the bounces. For my <200-user system with few bounces, I can deal with
this until I get SRS fully implemented with reverse-mapping.
