Configuration file for Sup mail sources
Export xapian entries to maildir sources on disk
sup-sync-back-maildir [options]
[source
uri ...]
This script parses the Xapian entries for a given Maildir source and renames (changes maildir flags) e-mail files on disk according to the labels stored in the index. It will export all the changes you made in Sup to your Maildirs so that they can be propagated to your IMAP server with e.g. offlineimap.
The script also merges some Maildir flags into Sup such as R (replied) and P (passed, forwarded), for instance suppose you have an e-mail file like this: foo_bar:2,FRS (flags are favorite, replied, seen) and its Xapian entry has labels 'starred', the merge operation will add the 'replied' label to the Xapian entry.
If you choose not to merge (-m) you will lose information ('replied'), and in the previous example the file will be renamed to foo_bar:2,FS.
Running this script is strongly recommended when setting the "sync_back_to_maildir" option from false to true in config.yaml or changing the "sync_back" flag to true for a source in sources.yaml.
If no source is given, the default behavior is to sync back all Maildir sources marked as usual and that have not disabled sync back using the configuration parameter sync_back = false in sources.yaml.
-n, --no-confirm
Don't ask for confirmation before synchronizing
-m, --no-merge
Don't merge new supported Maildir flags (R and P)
-l, --list-sources
List your Maildir sources and exit
-u, --unusual-sources-too
Sync unusual sources too if no specific source information is given
--version
Print version and exit
-h, --help
Show brief help message
