Re: [9fans] Unescaped From in mail items
Acme mail now reports multiple messages in the destination folders such
as:
111/ $199
110/ $349
109/ Apple [EMAIL PROTECTED] Tue 19 Jun 2007
iPod Gift Wrapping is now available.
upas/nedmail reports that the folder has 0 items in it, Acme mail that
it has 136 items.
Were the messages on the original server invalid before I started, is
acme mail handling them incorrectly when saving, or does upas/fs not
interpret them correctly after they've been saved locally?
this depends on your perspective. upas says that's invalid. this is what
i use to solve the problem by editing the mail. (sed converts to
runes -- that's why it is avoided.)

[9fans] Unescaped From in mail items
I've just been archiving a bunch of old email that was sitting in IMAP folders on a unix system somewhere into local folders on a plan9 system. I used acme mail to access the remote IMAP folder then save the items I wanted to local folders. Some of these have an unescaped ^From in the text, which seems to have caused problems when I've saved them to the local mail folders. The culprits seem to be multipart MIME, similar to: From [EMAIL PROTECTED] Tue Jun 19 12:14:30 EST 2007 Return-Path: ...
