How mails are sent from within Savannah
The internal vserver (10.1.0.101) is the reference mail server.
In particular, there is a Savane cron job there to create alias tables: /etc/aliases and /etc/email-adresses. This is used to map Unix user accounts to an outgoing e-mail, based on the 'email' field in the user's Savane account. alias tables are only updated in 'internal'.
All other systems delegate sending mail to internal.
- accounts, builder, frontend, sftp, vcs-noshell _and_ the host/dom0: an exim4 system is configured (see infra/exim_forwarder.txt):
- smarthost = 10.1.0.101
- QUEUERUNNER='queueonly'
- ZWiki: /MailHost object, SMTP Host = 10.1.0.101
