I don't think there are many people (or organisations) that keep their
e-mails in relational databases. Sure, mail servers like Exchange (or
Dovecot) may have their own on-disk-format for mailboxes instead of
plain maildirs or mboxes. But they don't use MySQL (or Postgres, for
that matter).

Exchange may not use MS SQL Server, but it does use a database,
namely Extensible Storage Engine (ESE) aka JET Blue (not the
same code as JET Red, which was the old Access engine). MS
looked at moving Exchange to SQL Server, but decided not to.

AFAIK, Exchange is the only major mail server to do this.
