| meillo@67 | 3 9.6.1. Mail transport agents (MTAs) |
| meillo@67 | 4 ----------------------------------- |
| meillo@67 | 5 |
| meillo@67 | 6 For a full-featured MTA, use `exim' in Woody and use `exim4' in Sarge. |
| meillo@67 | 7 [1] References: |
| meillo@67 | 8 * `exim-doc' and `exim-doc-html' packages for `exim' |
| meillo@67 | 9 * `exim4-doc-info' and `exim4-doc-html' packages for `exim4' |
| meillo@67 | 10 * http://www.exim.org/ |
| meillo@67 | 11 The only reasonable alternative MTA is `postfix' if you care about |
| meillo@67 | 12 security. `sendmail' and `qmail' are available as Debian packages but |
| meillo@67 | 13 are not recommended. |
| meillo@67 | 14 |
| meillo@67 | 15 If you do not need the relay capability of an MTA as in the case of a |
| meillo@67 | 16 satellite system such as a laptop PC, you may consider using one of |
| meillo@67 | 17 these lightweight packages: |
| meillo@67 | 18 * `ssmtp': needs an SMTP connection and is alias-capable, or |
| meillo@67 | 19 * `nullmailer': can spool but is not alias-capable. |
| meillo@67 | 20 At this moment, I find `exim' to be more suitable even for my personal |
| meillo@67 | 21 workstation machine, which is a laptop PC. |
| meillo@67 | 22 |
| meillo@67 | 23 You may need to remove `exim' for the installation of these |
| meillo@67 | 24 conflicting packages: |
| meillo@67 | 25 |
| meillo@67 | 26 # dpkg -P --force-depends exim |
| meillo@67 | 27 # apt-get install nullmailer # or ssmtp |
| meillo@67 | 28 |
| meillo@67 | 29 [1] Following sections use `exim' in examples. For Sarge replace this |
| meillo@67 | 30 with `exim4' as needed. |
| meillo@67 | 31 |
| meillo@67 | 32 9.6.1.1. Smarthost |
| meillo@67 | 33 ------------------ |
| meillo@67 | 34 |
| meillo@67 | 35 If you are running `exim4' or `exim' on a host which is connected |
| meillo@67 | 36 through the consumer grade services, please make sure to send outgoing |
| meillo@67 | 37 mail through a smarthost offered by your ISP or some others. [1] |
| meillo@67 | 38 There are few good reasons: |
| meillo@67 | 39 * to ensure SMTP retries since your ISP's smarthost usually have |
| meillo@67 | 40 more reliably connection. |
| meillo@67 | 41 * to avoid sending mail directly from a _dynamic IP address_ which |
| meillo@67 | 42 will likely be blocked by dial-up spam lists. |
| meillo@67 | 43 * to save your local bandwidth to send mails with multiple |
| meillo@67 | 44 recipients. |
| meillo@67 | 45 |
| meillo@67 | 46 The only conceivable exceptions are: |
| meillo@67 | 47 * the emergency cure for your ISP's SMTP service trouble. |
| meillo@67 | 48 * an experiment for the educational purpose. |
| meillo@67 | 49 * your host being a professionally hosted server. |
| meillo@67 | 50 |
| meillo@67 | 51 [1] You must follow this rule for any hosts on dial-up, DSL, cable |
| meillo@67 | 52 services or LAN through some broadband router. Even if your home host |
| meillo@67 | 53 has a fixed IP from your ISP, it is still a good idea to follow this |
| meillo@67 | 54 rule. Most workstations and home servers fall into this category. |
