279140changing relayhost based on sender
- Aug 3, 2011Hi, I'm searching for a way to effectively unset relayhost whenever an email goes through my postfix 2.7.0 server with a from address coming from either a specific email address, or from a specific domain or any email address from one of its subdomains.
sender_dependent_relayhost_maps seems like the right place to go with this, but I don't see a way to use a blank relayhost entry for the given email address.
Basically I imagine it like this:
# in main.cf
relayhost = smtp.example.com
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_maps
# in sender_maps
blah@... <unset relayhost>
.foo.com <unset relayhost>
foo.com <unset relayhost>
Let me know if I'm looking at this in the totally wrong way - thanks a ton!
