# 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).
