Overview
This Postfix charm implements a naive mail relay for cloud instances. It is expected that it will be used as a simple transport to a more intelligent upstream relay.
This is a reactive rewrite of ~paulgear/trusty/postfix-relay-0 which is based on the postfix charm by: - Menno Smits menno.smits@canonical.com - Frank Mueller frank.mueller@canonical.com - Horacio Duran horacio.duran@canonical.com - John Weldon johnweldon4@gmail.com

Configuration
- disable_vrfy_command
- (boolean) Disable the SMTP VRFY command. This isn't usually useful for relays.
- True
- domain_rewrite_map
- (string) A list of domain:newdomain pairs to rewrite. Primarily used for allowing hosts with locally-resolvable domain names to send mail which appears to be from a real domain. Addresses in these domains will be rewritten from user@host.domain to user+host@newdomain.
- myhostname
- (string) The external hostname by which this mail relay is known. This value must be changed for the charm to be useful.
- postfix-relay.example.com.
- mynetworks
- (string) A comma-separated list of networks for which this relay will allow sending mail.
- 127.0.0.0/8
- relayhost
- (string) An upstream mail relay, sometimes called "smart host". Enclose it in square brackets to skip MX lookup.
- smtp_auth_password
- (string) Password to auth against remote mail server using smtp_auth_username. Requires smtp_auth_username to take effect.
- smtp_auth_username
- (string) Username to auth against remote mail server. Requires smtp_auth_password to take effect.
- smtpd_helo_required
- (boolean) Require that a remote SMTP client sends HELO or EHLO before commencing a MAIL transaction.
- True
- smtpd_recipient_restrictions
- (string) Optional restrictions which the Postfix SMTP server applies in the context of a client RCPT TO command.
- permit_mynetworks, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_pipelining
- ssl_ca
- (string) Base64-encoded SSL CA to use with the upstream relay host. If set postfix will assume the upstream host is using TLS and configure itself accordingly.
