postfix
This role installs and manages Postfix, an SMTP server.
The debops.postfix role is designed to manage Postfix on different hosts in
a cluster, with different "capabilities". At the moment the role can configure
Postfix to act as:
- a null client: Postfix sends all mail to another system specified either via DNS MX records or an Ansible variable, no local mail is enabled (this is the default configuration);
- a local SMTP server: local mail is delivered to local user accounts;
- a network SMTP server: network access is enabled separately from other capabilities, to avoid exposing misconfigured SMTP server by mistake and becoming an open relay;
- an incoming MX gateway: Postfix will listen on the port 25 (default SMTP
port) and process connections using
postscreendaemon with automatic greylisting and optional RBL checking; - an outgoing SMTP client: Postfix will relay outgoing mail messages to
specified remote MX hosts, you can optionally enable SMTP client
authentication, the passwords will be stored separate from the inventory in
the
secret/directory (seedebops.secretrole). Sender dependent authentication is also available.
More "capabilities" like user authentication, support for virtual mail, spam/virus filtering and others will be implemented in the future.
This role can also be used as a dependency of other roles which then can
enable more features of the Postfix SMTP server for their own use. For
example, the debops.mailman role enables mail forwarding to the configured
mailing lists, and the debops.smstools role uses Postfix as mail-SMS gateway.
