mailsync  is  a  command line tool to keep collections of mailboxes synchronized. Mailboxes can reside on
       the local filesystem or on an IMAP server.

       mailsync can be invoked in three ways:

       mailsyncchannel        Synchronizes two sets of mailboxes. In c-client  taxonomy,  a  library  on  which
                               mailsync  relies  to  implement  mailbox  access,  mailboxes  are  referred to as
                               "stores".

       mailsyncstore          Lists the contents of a store. It's recommended to execture this  command  before
                               synchronizing  two  stores  to  check  whether  mailsync  is  seeing what you are
                               expecting it to see.

       mailsyncchannelstore  Lists what has changed in a store since the last sync.

-ffile  Use alternative config file.

       -n       Don't delete messages when synchronizing.

       -D       Delete any empty mailboxes after synchronizing..

       -m       Show from, subject, etc. of messages that are killed or moved when synchronzing.

       -M       Also show message-ids (turns on -m).

       -s       Says what would be done without doing it (turns on -n).  Attention: this will change the  "Seen"
                flag of emails and will create new, empty mailboxes in order to be able to compare them.

       -v       Show IMAP chatter.

       -vb      Show warning about braindammaged message ids

       -vw      Show warnings

       -vp      Show RFC 822 mail parsing errors

       -h       Show help.

       -d       Show debug info.  -di Debug/log IMAP protocol telemetry.  -dc Debug config.

                Use  mailsync with specified message-id algorithm. Currently you have the choice between md5 and
                msgid (default). msgid uses the Message-ID in  the  mail  header  to  identify  a  message.  md5
                calculates a MD5 hash from the "From", "To", "Subject", "Date" and "Message-ID" headers and uses
                that as message identifier.

                If  you use mailclients and servers that allow empty Message-IDs (f.ex. in mail drafts) then you
                should use the md5 algorithm.

       There   is   more   documentation   in   /usr/share/doc/mailsync   ,    and    in    /usr/share/doc/libc-clientxxxxxx/internal.txt
