It's worth it. And yes, it's worth upgrading to 2.0 too, if your Gnome
version is sufficiently recent. ;)

As the Message-IDs are generated de-centralized, there simply is no way
to guarantee its uniqueness.

I just searched my archives. For the script itself and a couple of
warnings, caveats and notes, please read this link (maybe the whole
discussions) and all links mentioned there.

Use it at your own risk. And make backups of your mail first. Paranoia
saves your day.

fetchmail, procmail, IMAP here, works great. You can filter dups on the
fly using the one formail command as a receipe in procmail, but
fetchmail itself should take care of not downloading the same bunch of
messages twice, even on a flaky connection.
