This manual page documents briefly the mailsync command.

mailsync is a way of keeping a collection of mailboxes synchronized. The mailboxes may be on the local filesystem or on an IMAP server.

There are three invocations of mailsync:

The first will synchronize two sets of mailboxes - in mailsync referred to as "stores".

The second form will list the contents of a store. It's usage is recommended before synchronizing two stores to check whether mailsync is seeing what you are expecting it to see.

The third form will show you what has changed in a store since the last sync.

A summary of options is included below.

-f file

Use alternate 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 would 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

-vp

-h

Show help.

-d

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

-t mid

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
