To test and benchmark several common SMTP servers for Unix. This is inspired by the work done by Matthias Andree at his Postfix vs. qmail - Performance page.

VacuumMail is an AppleScript application that performs the “vacuum” command on Apple Mail’s underlying SQLite Envelope Index database. This must not be done while Mail is running, so this scriptlet first checks to see if Mail is running and if so, quits Mail. VacuumMail first notifies the user that it will be shutting Mail down, giving the user an opportunity to cancel the vacuum operation.
