All
I wish to be able to only apply a rewrite rule to email that comes from
machines in given subnets rather than a whole domain.
Lets say there are a few thousand machines in domain.com however I only wish
to apply rewrite rules to mail I send out originating from machines in
192.168.160.0/24 and 192.168.164.0/24 and no others though they are all in the
same domain as machinename.domain.com.
I may however be looking at this wrong, the real issue is we have a top level
domain in which all computers sit, however only the email our users send from
machines in our area should be rewritten.
Currently I have the rewrite rule restricted to the *.domain.com however if
people elsewhere in the domain send email to someone in out area and their
username matches one of ours it gets rewritten.
*@*.domain.com ${lookup{$1}lsearch{/etc/mail.rewrite}{$value}fail} fFs
where mail.rewrite contains lines like
username:otheraddress@???
I suspect I may be able to do this by attaching the rewrite rule to some
specific part of the mail process, like the transport, however I cant quite
work out how or if it would be correct and only then rewrite for our own users
and not others.
We only relay for people on the subnets I wish to restrict this to if that
helps.
See You
Steve
