  • disable_vrfy_command | boolean

    Default: True

    Disable the SMTP VRFY command. This isn't usually useful for relays.

  • 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.

  • mynetworks | string


    A comma-separated list of networks for which this relay will allow sending mail.

  • 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

    Default: True

    Require that a remote SMTP client sends HELO or EHLO before commencing a MAIL transaction.

  • smtpd_recipient_restrictions | string

    Default: permit_mynetworks, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_pipelining

    Optional restrictions which the Postfix SMTP server applies in the context of a client RCPT TO command.

  • 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.
