SMTP unroutable address
I solved the problem by creating a new router, inside the .ifdef DCconfig_internet
block:
my_domain:
debug_print = "R: dnslookup for $local_part@$domain"
driver = dnslookup
domains = domain.com
transport = remote_smtp
# ignore private rfc1918 and APIPA addresses
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 : 192.168.0.0/16 :\
172.16.0.0/12 : 10.0.0.0/8 : 169.254.0.0/16 :\
255.255.255.255
no_more
This forces a remote delivery (via standard dnslookup) even for *@domain.com
addresses, which is exactly what I wanted.
There may be an easier way to achieve this, by modifying the existing routers, but this "works for me".

I have set up gmail google app accounts for our own domain,
domain.com
, so that email is handled by gmail. I.e. MX records point to google servers, A records to our own server IP. This works fine.Now I tried sending emails from our machine (via
crontab
, using Debian'sexim4
) to our own email address, e.g.[email protected]
.This doesn't work. Presumably exim is seeing the address as local and fails to forward it to the google servers. The delivery fails with:
Subject: Mail delivery failed: returning message to sender This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [email protected] Unrouteable address
and is then unhelpfully delivered to
/var/mail
.Emails to other addresses -- outside of
domain.com
-- work ok.I looked at the configs under
/etc/exim4/conf.d/
but couldn't make sense of it.Any help is welcome. Cheers!
