Sujet: [Exim] disabling sender verification for one domain
--
This is probably a dumb question but it has me stumped.

exim is happily bouncing mails from my internal LAN which have a nonexistant
domain of "linsec.vx", so mail from root@??? is bouncing
because it can't do a sender verify. I like having the sender verify there
but want to exclude @.*linsec.vx from the domains that get the verify. In
other words, I'd like to arbitrarily skip sender verify on .*linsec.vx, but
keep it for everything else.

I've been mucking around all day with exim working on ACLs and all kinds of
other fun stuff and have managed to work my way through everything except
this. I really don't know where or what to put. I know it needs to go in
acl_check_rcpt and most likely in the first stanza:

accept hosts = :
deny   local_parts = ^.*[@%/|] : ^\\.
accept local_parts = postmaster
       domains - +local_domains
require verify = sender


I don't see any options with sender that can be used like this (like
sender:!.*.linsec.vx or something).

Is this even possible to accomplish? I would suspect so with the remarkable
things exim can do, but this one has me really stumped and I suspect it's
because (although I'm understanding them more and more) ACLs are still a
little complicated to me.

Thanks for any pointers.
