Re: sendmail vs postfix

Postfix is quite a good mailer. Its much more straight forward to
configure and with less gotchas than sendmail. 

You need to check in /etc/postfix. All you configuration lives in there.
Theres a couple of config files with different purposes. They all have
good documention in the files as comments. 

I think you need /etc/postfix/transport

Which has in as a comment:

#        domain transport:nexthop
#               Mail  for  domain is delivered through transport to
#               nexthop.
#
#        .domain transport:nexthop
#               Mail for  any  subdomain  of  domain  is  delivered
#               through  transport  to  nexthop.  This applies only
#               when the string transport_maps is not listed in the
#               parent_domain_matches_subdomains configuration set-
#               ting.  Otherwise, a domain name matches itself  and
#               its subdomains.

Postfix is quite easy to get going. I wouldnt worry too much about
having it sorted before you jump in :) Just remember the main ones:

postfix reload 
postfix check

And read the comments in the config files!

The postfix-users list is good too.
