ImapFix: a filter/fixer for IMAP mailboxes

You can leave this running on a server somewhere and connect to your IMAP account from different machines/devices. Processed messages are moved from the inbox to a folder called in unless otherwise directed by your filters.

Selected features: (see program for a full list)

• Can use SpamProbe
• Converts non-ASCII headers and body to Unicode when possible, so you can connect with a device that can’t handle other encodings
• Move very large message bodies into attachments, to work around display problems on some devices
• Create “thumbnails” of large images so they can be previewed on low-bandwidth connections
• Can use tnef and soffice to unpack winmail.dat and add HTML or PDF versions of office documents, so you can view these on devices that don’t otherwise support them
• Move mail between IMAP and local Maildirs
• Move old mail to compressed archives, saving attachments separately and merging duplicates; archives can be searched along with current mail
• Periodically check additional IMAP accounts and process their mail as if it had been sent to the first
• Rewrite delivery failure reports, adding the failed address to the Subject when possible
• Rewrite the “importance” flag according to your own rules
• Manage folders named after dates, for postponing messages and notes to a specific future date
• Can add arbitrary Python code to the rules, and/or run extra code on messages that were SSL-authenticated as from yourself (for email-based remote control)
