Hi, I'm setting up a light weight exim4 just for local use.

<devon-debian> ( <->switch--- rest of network.

i have been succesful in sending mail from thunderbird( as 
well as receiving it(a particular mda handling pop).

I have not setup anything special than use dpkg-reconfigure exim4, chose 
it as internet mail system, not using a smarthost.. and I'm stuck on a 
single issue.

My main issue is I'd like a small embedded device to send logs by 
e-mail. (a dns321 if it helps) But this device's messages get dropped..

"devon:~# exim4 -bh

**** SMTP testing session as if from host
**** but without any ident (RFC 1413) callback.
**** This is not for real!

 >>> host in hosts_connection_nolog? no (option unset)
 >>> host in host_lookup? no (option unset)
 >>> host in host_reject_connection? no (option unset)
 >>> host in sender_unqualified_hosts? no (option unset)
 >>> host in recipient_unqualified_hosts? no (option unset)
 >>> host in helo_verify_hosts? no (option unset)
 >>> host in helo_try_verify_hosts? no (option unset)
 >>> host in helo_accept_junk_hosts? no (option unset)
220 devon ESMTP Exim 4.69 Tue, 27 Jul 2010 18:14:40 -0400
LOG: SMTP command timeout on connection from []
421 devon: SMTP command timeout - closing connection

^ exim4 -bg would show the same output..

I'm using a small little dns central server calle nslu2 (,

The domains are each master zones, one master for "dns321" and one 
master for devon.local.

I was looking at the options and have been trying to disable host_lookup 
or exception rules so that the dns321 name (i believe dns321 is not 
fulfilling security requirement in having a localpart of a domain name) 
or ip address can pass unconditionally..

Dns321 has a reverse-ip add record..

I know there's exim-users mailing list from exim4.org, but I'm wondering 
if there's something 'debian' about
the exim4-daemon-light package that i'm not getting.

"exim4 -bP recipeint_unqualified_hosts" and -bp host_lookup is null

Any rtfm I should look into?

What can I use to disable the validation of smtp senders?
(tcpdump shows me there's smtp communication, and i also check exim4 -bp 
shows empty queue)

I'm guessing my dns321 is acting like it needs to be authenticated 
unlike thunderbird..

I know this sounds very stupid, but please bare with me, I'm really new 
to this..

Thank you for any reply, greatly appreciate it..
