I am trying to set up e-mail delivery between a couple of hosts in my
lan. So far, I am unable to get the "current" host to relay messages to
its neighbour because the "infrastructure" fails to inform smtpd (on
current) about the MX record for the local neighbour domain. The local
aliases for hosts are configured in /etc/hosts:
10.3.0.3 tryggve.lan try.lan tryggve try
10.3.0.6 raptor.lan rap.lan raptor rap
Is there a way to configure opensmtpd to accept e-mails for hosts in
/etc/hosts or for static IP addresses without setting up a DNS server
with a real (or fake local) domain and an MX for that domain?
Here is what I have done:
email from workstation:
$ mail root@try
Subject: Hello from raptor.lan
Dear Tryggve.lan,
Please accept my messages.
You should do so because I told you to:
accept from source { 10.3.0.0/24 }
----
I think that the "try" alias shoud work because on the workstation, I have:
accept from any for domain { "tryggve", "try", "tryggve.lan" } \
relay hostname "tryggve.lan"
---
But, regardless of that, even if I send to [email protected] or even
[email protected], there is still no DNS in my lan and therefore, smtpd says:
