hi all,
i've 2 mail servers on the same MAT'd LAN:
primary domain listener IP machine LAN name
_________________ ____________ ____________________
mail.domain1.com 10.0.0.1 box1.mydomain.com
mail.domain2.com 10.0.0.2 box2.mydomain.com
each server delivers mail for its resident, "local domains" w/ :
localuser:
driver = accept
domains = +local_domains
transport = dovecot_lda
dovecot_lda:
driver = pipe
command = /.../deliver \
-c /.../dovecot-deliver.conf \
-d $local_part@$domain
message_prefix = ""
message_suffix = ""
delivery_date_add
envelope_to_add
return_path_add
log_output
user = blahblah
it works fine.
all mail from each server to external hossts uses the typical dnslookup + smtp:
dnslookup:
driver = dnslookup
domains = !+local_domains
ignore_target_hosts = +rfc3330_hosts
same_domain_copy_routing
no_more
cannot_route_message = Invalid domain part in email address
transport = remote_smtp
remote_smtp:
driver = smtp
hosts_avoid_tls = :
hosts_require_tls = :
tls_require_ciphers = ALL:!SSLv2:!aNULL:!NULL:!EXPORT:!DES:!LOW:@STRENGTH
also OK for sending to external MX's.
but, NOTE that i've added the 'ignore_target_hosts' exclusion to the dnslookup,
avoding delivery to the typical RFC3330 hosts:
hostlist rfc3330_hosts = 0.0.0.0/8 :\
10.0.0.0/8 :\
127.0.0.0/8 :\
169.254.0.0/16 :\
172.16.0.0/12 :\
192.0.2.0/24 :\
192.168.0.0/16 :\
198.18.0.0/15 :\
224.0.0.0/3
this -- seemingly -- prevents the delivery from 'mail.domain1.com' to
'mail.domain2.com' using the dnslookup router.
what's the cleanest way to deal with this? i'm flailing around with
manualroutes, 'hardwiring' my lan into rfc3330_hosts, etc etc., but honestly am
a bit confused as to the 'right' approach ...
any suggestions/pointers would be appreciated at this hour ... or any other ! =)
cheers,
richard
