     1.6 +9.6.1. Mail transport agents (MTAs)
     1.7 +-----------------------------------
     1.8 +
     1.9 +     For a full-featured MTA, use `exim' in Woody and use `exim4' in Sarge.
    1.10 +     [1] References:
    1.11 +        * `exim-doc' and `exim-doc-html' packages for `exim'
    1.12 +        * `exim4-doc-info' and `exim4-doc-html' packages for `exim4'
    1.13 +        * http://www.exim.org/
    1.14 +     The only reasonable alternative MTA is `postfix' if you care about
    1.15 +     security.  `sendmail' and `qmail' are available as Debian packages but
    1.16 +     are not recommended.
    1.17 +
    1.18 +     If you do not need the relay capability of an MTA as in the case of a
    1.19 +     satellite system such as a laptop PC, you may consider using one of
    1.20 +     these lightweight packages:
    1.21 +        * `ssmtp': needs an SMTP connection and is alias-capable, or
    1.22 +        * `nullmailer': can spool but is not alias-capable.
    1.23 +     At this moment, I find `exim' to be more suitable even for my personal
    1.24 +     workstation machine, which is a laptop PC.
    1.25 +
    1.26 +     You may need to remove `exim' for the installation of these
    1.27 +     conflicting packages:
    1.28 +
    1.29 +          # dpkg -P --force-depends exim
    1.30 +          # apt-get install nullmailer         # or ssmtp
    1.31 +
    1.32 +[1]  Following sections use `exim' in examples.  For Sarge replace this
    1.33 +     with `exim4' as needed.
    1.34 +
    1.35 +9.6.1.1. Smarthost
    1.36 +------------------
    1.37 +
    1.38 +     If you are running `exim4' or `exim' on a host which is connected
    1.39 +     through the consumer grade services, please make sure to send outgoing
    1.40 +     mail through a smarthost offered by your ISP or some others.  [1]
    1.41 +     There are few good reasons:
    1.42 +        * to ensure SMTP retries since your ISP's smarthost usually have
    1.43 +          more reliably connection.
    1.44 +        * to avoid sending mail directly from a _dynamic IP address_ which
    1.45 +          will likely be blocked by dial-up spam lists.
    1.46 +        * to save your local bandwidth to send mails with multiple
    1.47 +          recipients.
    1.48 +
    1.49 +     The only conceivable exceptions are:
    1.50 +        * the emergency cure for your ISP's SMTP service trouble.
    1.51 +        * an experiment for the educational purpose.
    1.52 +        * your host being a professionally hosted server.
    1.53 +
    1.54 +[1]  You must follow this rule for any hosts on dial-up, DSL, cable
    1.55 +     services or LAN through some broadband router.  Even if your home host
    1.56 +     has a fixed IP from your ISP, it is still a good idea to follow this
    1.57 +     rule.  Most workstations and home servers fall into this category.
