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. 1.58 +
