Thanks - makes it much easier to see what's going on. The 550 is a
result of the sender address failing to verify - here's the relevant
bit of output:

So crm.deev.com is resolving to 192.168.0.68 (not sure if by A or MX,
but it matters little). You have a 'ignore_target_hosts' directive in
your dnslookup router which tells it to ignore 192.168.0.0/16, so the
router declines. No other router is able to route mail to
crm.deev.com, so the verify fails and the ACL rejects the message.

Presumably you never need to deliver mail back to @crm.deev.com, so
you could exempt that domain from the verify=sender ACL, or provide a
verify_only router to make the verify work:

verify_crm:
driver = accept
domains = crm.deev.com
verify_only = yes

If you do need to delive mail there, you'll need to remove the IP
address in question from the ignore_target_hosts directive in the
dnslookup router.
