Mail

New mailserver plans

• An IMAP/SSL server! Yay
• Two separate servers:
  • One handling all incoming, external mail, and does spam filtering
  • One containing all mail boxes (IMAP), sending out internal mail

• Alias files copied to secondary MXes
• Using cdb
• Exim! (sorry) and Dovecot
• Mailinglists without specific aliases, just by looking at the -l postfix or lists.wikimedia.org

Old Wikimedia email setup

• postfix, mailman, OTRS, spamassassin on goeje
  • mail.wikimedia.org <- service ip/name for mail
  • secure.wikimedia.org <- service ip/name for OTRS
  • ticket.wikimedia.org <- service name for OTRS, redirects to secure.wikimedia.org currently
  • srv38 is the mysql server for OTRS
• sendmail on most other machines (apaches)
  • internally in pmtpa they forward to smtp.pmtpa.wmnet, which relays to the external world.

How to make an email alias

On goeje:

vi /etc/postfix/aliases
newaliases
postfix reload

It takes up to 15 minutes until the secondary MXes accept mail for new aliases.
