How does your script deal with the users' IMAP passwords, or prevent
the sudo-priveleged users from reading each others' emails?
I was interested in seeing how this problem would be tackled "through"
IMAP. I should be able coerce mutt into writing a fresh cache of the
headers in an INBOX thus:
Run mutt with a special configuration file: mutt -F conffile
and open the appropriate inbox: -f imaps://.../INBOX
readonly if required: -R
conffile contains:
set header_cache=some-empty-directory
set imap_headers="X-ORIGINAL-TO RETURN-PATH"
set spoolfile="imaps://...passwords.../INBOX
The cache will appear in a folder under some-empty-directory and
any non-default headers can be included by setting imap_headers.
It might be sufficient to specify -f '!' (as spoolfile is set).
file says the resulting cache is a "Tokyo Cabinet (1.0:911)" and
I have no idea how to list its contents. It would be neat to have
a customised listing (with width unrestricted by the terminal) of
my INBOX on the IMAP server to which I *don't* have privileged access.
Cheers,
David.
