What I'm trying to do is set up a domain-wide filter (called with -m as a
postfix transport). I have postfix (as arg $2) passing a list of
recipients from the envelope. I need to take the first recipient from
that arg and parse the domain out of the address (unfortunatly postfix
doesn't deliver that variable in any way to a piped transport).
I can see from all the FAQ's, etc. how to go about parsing from a header
and doing an extraction but I can't see how to do this from an existing
variable. Can anyone give me a pointer?
To test against a variable (say $VAR) you use '??' on the condition
line. For example:
* VAR ?? blah
will deliver to 'mymailbox' if $VAR contains 'blah'.
So I think that what you're asking for is something along the lines of:
* MYARG ?? \<interesting\.domain\.kom\>
Is that the sort of thing you want?
As an aside, you might expect (since you have the thing in which you are
interested stored in the variable $2) to be able to do something like:
* 2 ?? \<interesting\.domain\.kom\>
to test the variable $2 directly...but that doesn't seem to work. At
least not in version 3.15.2
Hope that helps,
