I have a multihomed network (Cable/HFC from OptimumOnline, DSL from
Verizon) with a default route through OptimumOnline which has stopped
passing port 25 traffic. These are NAT'ed LAN networks 192.168.1.0/24
and 10.123.119.0/24 respectively, with 192.168.1.0/24 as the default
route/network. I'm using DynDNS's MailHop service to act as primary
MX which then resends on a high order port to my local exim which is
listening on 192.168.1.20. Outgoing mail smarthosts through my ISP
already.
I want to teach exim to do Sender Callout Verification through the NI
that attaches to the DSL network by the IP address 10.123.119.19 and
does permit port 25 traffic. It would seem as if the "interface"
qualifier should be useful here.
I have the following RCPT ACL:
warn !verify = sender/callout
domains = !+noverify_domains
message = X-Exim-Sender-Verify: failed - $acl_verify_message
log_message = sender verify failed: $acl_verify_message
I tried creating the following router and transports:
this_router_verifies_addresses:
driver = dnslookup
domains = !+local_domains
transport = verify_smtp
verify_only
verify_smtp:
driver = smtp
interface = 10.123.119.19
remote_smtp:
driver = smtp
Yet it always seems to try and callout through the default NI regardless.
What am I missing here?
