[nflug] Setting up local MTA as relay questions

Fri Sep 29 13:13:57 EDT 2006

Here is my Debian conf (debian builds the exim file when exim start from this conf 

# /etc/exim4/update-exim4.conf.conf
#
# Edit this file and /etc/mailname by hand and execute update-exim4.conf
# yourself or use 'dpkg-reconfigure exim4-config'
#
# Please note that this is _not_ a dpkg-conffile and that automatic changes
# to this file might happen. The code handling this will honor your local
# changes, so this is usually fine, but will break local schemes that mess
# around with multiple versions of the file.
#
# update-exim4.conf uses this file to determine variable values to replace
# the DEBCONFsomethingDEBCONF strings in the configuration template files.
#
# Most settings found in here do have corresponding questions in the
# Debconf configuration, but not all of them.
#
# This is a Debian specific file

## ALL Mail seems to be getting grabbed by the smarthost router even though the localdomain is set as jjn.com and ! +localdomains should not accept mail as root at jjn.com....  I'm confused - I think it's right but I've been staring at it too long!

I tried to send from one user on machien to other user (jjneff is getting rename to my google account name

Still Trying to go via Smarthost - somehow the jjn.com is not being seen as localdomains
$$$ Mail for the intenet IS going out roght so that's good

Including your exim config file and some example log entries that 
illustrate the problem would be extremely valuable in helping to 
troubleshoot your problem.

Without seeing that, my best guess would be that you likely just need to 
add localhost.localdomain to a domainlist that you specify the local 
domains in, and later refer to in a router that uses this.

For example, a simplified version of my exim4 config for my valites.net 
domain would be as follows:

domainlist local_domains = @:@[] : localhost : valites.net

One of my routers:

local_user:
   debug_print = "R: local_user for $local_part@$domain"
   driver = accept
   domains = +local_domains
   check_local_user
   local_parts = ! root
   transport = maildir_home

The corresponding transport:

maildir_home:
   debug_print = "T: maildir_home for $local_part@$domain"
   driver = appendfile
   directory = $home/Maildir
   create_directory
   delivery_date_add
   envelope_to_add
   return_path_add
   maildir_format
   maildir_tag = ,S=$message_size
   mode = 0600
   mode_fail_narrower = false

Integration into your config may be slightly different.
