Hi all.
After a lot of experimentation and successful digging in the list
archives via google, I finally managed to get some rewrite rules to
accomplish the following task:
The from:-field for mails that have a given address in either the to: or
the cc:-field will be rewritten to another (local) address.
You might ask for the use of this behaviour: I'm subscribed to several
mailing lists that only accept messages from members. For every
subscription I use a distinct mail address for several reasons, but when
writing to such a list I sometimes forget to properly adjust the
from:-field. That results in additional work for the list admin, which I
want to avoid.
As stated above, I successfully set up rules that do what I want. One
example:
real@??? \
"${if or {{match {$header_to:}{exim-users@???}} \
{match {$header_cc:}{exim-users@???}} \
{match {$header_to:}{exim-users-request@???}}} \
{exim-users@???}fail}" Ffrs
If I forget to adjust from:, the mail comes from my "real" e-mail
address real@??? (which is just an example). In case the mail is
directed to this list (or exim-users-request) from: will be adjusted to
exim-users@???.
Since sooner or later there will be a lot of rules (depending on the
amount of lists I'm subscribed to), I wonder if it is possible to make
these stuff a little easier to administrate.
So we come to the following question: is it possible to use just some
general rules that look up every part of to: and cc: in a file, and if
the address is found in the file, the rule uses a value that is given
there? An example for the "lookup file" I have in mind:
exim-users@??? exim-users@???
The first part of the line is the list address, the second is the mail
address that from: should be changed to if the list address is contained
in either to: or cc:.
Is that possible? And if so, how could I do this (examples)?
Bye, Mike
