Chat Mail server configuration

This package deploys Postfix and Dovecot servers, including OpenDKIM for DKIM signing.

Postfix uses Dovecot for authentication as described in https://www.postfix.org/SASL_README.html#server_dovecot

Ports

Postfix listens on ports 25 (smtp) and 587 (submission) and 465 (submissions). Dovecot listens on ports 143(imap) and 993 (imaps).

DNS

For DKIM you must add a DNS entry as in /etc/opendkim/selector.txt (where selector is the opendkim_selector configured in the chatmail inventory).
