This page will document the process for migrating email and mailing list services for WMUK to the new server infrastructure.

Mail servers work as follows; an SMTP server acts as the core Mail Transfer Agent (MTA) receiving and sending mail for users. This mail is then stored on disk, either in Maildir or Mbox format. A second server will provide POP3 & IMAP (i.e. mailbox) access to users by reading those delivered files.

In practice migrating the archives is relatively simple, however locating all the configuration settings and mail and ensuring it is adequately migrated will take a little time.

Current setup

Software:

  • Qmail (SMTP)
  • Courier (POP3 & IMAP)
  • SpamAssassin (anti-spam)
  • Mailman (mailing list)

Mail is stored in Maildir format & accounts are configured using Plesk Panel.
