• If the message is missing on one side and is new (not listed in the msinfo file),
it is transmitted there.
• If the message merely exists on one side and is old (already listed in the msinfo
file), it is deleted there (because the message that had obviously existed on the
other side was deleted).
To know in advance which messages will be transmitted and which will be deleted
during a synchronization, start mailsync with a channel and a store with
mailsync folder localdir. This command produces a list of all messages that
are new on the local host as well as a list of all messages that would be deleted on the
IMAP side during a synchronization. Similarly, the command mailsync folder
imapdir produces a list of all messages that are new on the IMAP side and a list of
all messages that would be deleted on the local host during a synchronization.
40.7.2 Possible Problems
In the event of a data loss, the safest method is to delete the relevant channel log file
msinfo. Accordingly, all messages that only exist on one side are viewed as new and
are therefore transmitted during the next synchronization.
Only messages with a message ID are included in the synchronization. Messages lacking
a message ID are simply ignored, which means they are not transmitted or deleted. A
missing message ID is usually caused by faulty programs when sending or writing a
message.
On certain IMAP servers, the main folder is addressed with INBOX and subfolders are
addressed with a randomly selected name (in contrast to INBOX and INBOX.name).
Therefore, for such IMAP servers, it is not possible to specify a pattern exclusively for
the subfolders.
After the successful transmission of messages to an IMAP server, the mailbox drivers
(c-client) used by mailsync set a special status flag. For this reason, some e-mail pro-
grams, like mutt, are not able to recognize these messages as new. Disable the setting
of this special status flag with the option -n.
