I am routing all mail for a domain to another SMTP server using the
transport map rule
adomain.com relay:other.server
But I would like to exclude mailing lists, and have them processed locally,
using header_checks entries like this:
/^X-Mailing-List:/ FILTER local:
Here, "local" is the transport name, and the destination is empty as
suggested in the
comments of the header_checks file. But that doesn't work, no filtering
takes place,
the mail ends up being relaid.
/^X-Mailing-List:/ REDIRECT some@address
does work, but I would prefer not to change the address.
Obviously there is a misunderstanding on my part regarding the FILTER syntax
Can I use a FILTER action to do what I want? I'm using Postfix 2.7.5
Thanks,
Pim
