Application-specific email configuration for exim is covered in doc/INSTALL-exim4.md. It is possible to use other MTAs; the documentation for exim should provide you with enough information to get started with a different MTA. If you do use a different one, please add to the documentation!
On a live server, you should also consider the following, to increase the deliverability of your email:
- Set up SPF records for your domain
- Set up feedback loops with the main email providers (Hotmail and Yahoo! are recommended)
- Especially if deploying from Amazon EC2, use an external SMTP relay for sending outgoing mail. See Alaveteli EC2 AMI for more suggestions.
Most of the data for the site lives in the production database. The exception is the raw incoming email data, which is stored on the filesystem, as specified in the setting RAW_EMAILS_LOCATION of config/general.yml.
Refer to the Postgres documentation for database backup strategies. The most common method is to use pg_dump to create a SQL dump of the database, and backup a zipped copy of this.
Raw emails would be best backed up using an incremental strategy. Rsync is one way of doing this.
