Thanks for the help Joseph (and Stephen)...
This 'if' block is just a bunch of separate one line tests that, if any
of them match, result in the vacation response not being sent, so it
doesn't really matter what is above them (they are all the defaults,
this is the only line I am modifying)...
This line should simply examine any from header, and if any of the
included strings are found *anywhere* in the from address, local or
domain part, so, either side of the '@' sign, and regardless of any dots
anywhere in the string.
I imagine that is why the guys from postfixadmin used the * and maybe
the +? Like I said, I've got no experience with regex at all - guess its
time to learn eh? ;)
Anyway, I want the regex such that any/all of the following from
addresses would match (along with all of the other strings):
bounce-anything at example.com
anything at bounce.example.com
anything at bounce-reply.example.com
facebook at example.com
anything.facebook at example.com
anything-facebook at example.com
anything at something.facebook.com
Hopefully that is enough examples...
Basically, if *any* of the strings I might specify inside the
parenthesis match individually anywhere in the from address, then don't
send the response (ie, positive match).
Thanks again, it is really appreciated...
