Configuring DKIM

DKIM configuration is available in Aurora Corporate. You'll need to generate DKIM keys, one of the services which can do that for you is:

You will need to supply the keys in DNS records of your domain, and in Exim configuration file /etc/exim4/exim4.conf:

DKIM_FILE                       = /opt/afterlogic/etc/ssl-certs/dk.key
DKIM_PRIVATE_KEY                = ${if exists{DKIM_FILE}{DKIM_FILE}{0}}
DKIM_DOMAIN = ${lc:${domain:$h_from:}}
remote_smtp:
    driver = smtp
    dkim_domain           = DKIM_DOMAIN
    dkim_selector         = mail
    dkim_private_key      = DKIM_PRIVATE_KEY
    user = afterlogic
    group = afterlogic
    interface = xx.xx.xx.xx

Most of those lines are already there but they're commented out, be sure to uncomment those and specify selector (mail in the sample, can be anything else) and the proper external IP.
