CSB Email --Technical Notes November, 2004

CSB mail server

A server sits inside the firewall, with the name (or DNS alias) mail.csb.core. It is accessed through the firewall via a tunnel from mail.csb.yale.edu.

Alias file

The alias file /etc/postfix/aliases is divided into sections.

1. Standard mail aliases, like postmaster.
2. Aliases that do not correspond to usernames (such as mailing list aliases), whether they point to internal or external mailboxes.
3. Users with active CSB computing accounts, who receive email elsewhere. This section should be aphabetical by alias.
4. Alumni, and others who have no CSB account, but for whom we forward mail. This section is sorted by date, with entries deleted after 2 years.
5. Alumni, as above, who have a permanent tenancy, sorted by user.
6. Alumni, and others who have no CSB account, but for whom we no longer forward mail. These aliases will be silently discarded by forwarding to /dev/null. Within this section, they should be sorted alphabetically by alias.

Users who receive their email locally will not have an entry in the alias file.

User Management

When a new CSB account is added the user will provide his/her Yale (or other outside) email address, and the alias will be added to /etc/postfix/aliases on mail.csb.core, amd newaliases will be run.

When a CSB account is closed, the user's alias will be moved to the active alumni section (if a forwarding address is available) or to the bitbucket alumni section.

At irregular intervals, aliases that have passed their expiration date will be moved to the bitbucket section.

Outgoing Mail -- smtp.csb.core

The outgoing email server will accept mail only from within the core, or specific individual hosts/users. It should rewrite headers so that mail appears to come from (user@mail.csb.yale.edu? of 1st.last@yale.edu).
