6 # This script makes mail indexers (like mairix, mu or nmzmail) together with
9 # These search engines usually create a virtual maildir containing symbolic
10 # links to the original mails, which can be browsed using mutt.
11 # It would be optimal if mutt somehow knew that the two maildir entries
12 # identify the same mail, but this is not that easy (mail folder
13 # abstraction from different formats, no tight integration of mail indexers).
15 # So if one wants to rename (for setting/clearing flags), delete or edit the
16 # mails, it is only possible using the original mail. This (very simple)
17 # script helps to jump to this message, using e.g. this macro in .muttrc:
19 # macro generic ,j "<enter-command>push <pipe-message>muttjump<enter><enter>" "jump to original message"
21 # one of: mairix, mu, mu-old (mu < 0.7) and nmzmail

28 # If set to "auto", the $STY environment variable is used for auto detection.

32 # If this is set to "yes", muttjump will not open a new instance of

87 This script calls mutt, jumping to the message given in stdin or to the message
88 identified by "msgid". With "-R", it jumps to the message being replied to.
89 It uses a mail search engine (currently mairix, mu and nmzmail are supported),
90 which has to be configured through MUTTJUMP_INDEXER variable.
