"Read/sync your IMAP mailboxes". Using this to back up Gmail.

"A tool to copy messages from one IMAP server to another quickly and safely. It’s smart enough not to copy messages that already exist on the destination and robust enough to deal with interruptions caused by flaky connections or misbehaving servers."

"Fast, reliable, and secure with unmatched spam control."

Because I always forget the URL.

Handy for imap info
