Loading the support system
To begin, locate your system's Exim configuration files. In most distributions these will be in /etc/exim, if not try 'locate exim.conf'.
By default, Exim does not include a password or access file. In this example, we'll create our own file at /etc/exim/access. Entries in this file should follow the format of 'key: auth_name=username auth_pass=secret auth_plain=username^@secret'.
Add an entry to the access file for Easy-SMTP. Remember to replace the accountid, user, and password with your own authentication details.
$ echo "easysmtp_auth: auth_name=ACCOUNTID\user auth_pass=password auth_plain=ACCOUNTID\user^@password" >> /etc/exim/access $ chown root:root /etc/exim/access $ chmod 600 /etc/exim/access
where ^@ represents the NULL character.
Add the following to /etc/exim/exim.conf.
... MAIN_TLS_ENABLE = 1 ... |
Add the following to the Exim routers in /etc/exim/exim.conf.
...
outgoing:
driver = manualroute
domains = !+local_domains
route_list = * ssrs.reachmail.net
transport = easy_smtp_relay
...
Add the following to the Exim transports in /etc/exim/exim.conf.
...
easy_smtp_relay:
driver = smtp
hosts_require_tls = ssrs.reachmail.net
hosts_try_auth = easysmtp_auth
tls_require_ciphers = SSLv3+TLSv1
...
Add the following to the authenticator configuration. Autheticators may or may not be configured by default in your Exim installation. If not, make sure to include the 'begin authenticators' line before the authenticators in the config file.
...
plain:
driver = plaintext
public_name = PLAIN
client_send = "${extract{auth_plain}{${lookup{$host}lsearch{/etc/exim/access}{$value}fail} }}"
...
Restart exim. Note that your command to restart exim may be different
$ /sbin/service exim restart |
If you want to route only certain domains through Easy-SMTP, the easiest solution is to change the route_list variable in the smart host router. In this example, the route_list will be defined by a file at /etc/exim/
esroutes with entries formatted as “domain relay-host”.
Add the domain relay definitions to /etc/exim/esroutes
$ echo "some-domain.tld ssrs.reachmail.net" >> /etc/exim/esroutes $ echo "some-other-domain.tld ssrs.reachmail.net" >> /etc/exim/esroutes $ chown root:root /etc/exim/esroutes $ chmod 600 /etc/exim/esroutes
Change the route_list variable in the smart_host_relay router of /etc/exim/exim.conf
... route_list = /etc/exim/esroutes ... |
Restart Exim. Note that your command to restart Exim may be different.
$ /sbin/service exim restart |
