Speed Up Mail – Mac Kung Fu, 2nd Edition

Tip 357Speed Up Mail

If you find Mail has slowed a little, try rebuilding its message index databases. Ensure the Inbox is selected (rather than a single mailbox), and then click MailboxRebuild. Depending on how many messages you have, it might take some time to complete, but it takes place in the background, and Mail is still completely usable while rebuilding takes place. You can even quit and restart the program, and it’ll just pick up rebuilding where it left off.
