syncmaildir binary package in Ubuntu Precise amd64

 Sync Mail Dir is a set of utilities to synchronize a pair of mail boxes
 in Maildir format, using SSH to transfer data. It provides the smd-pull
 utility to pull changes made on the remote mailbox, smd-push to propagate
 local changes to the remote mailbox, smd-loop to iterate push and pull
 in a timely way.
 .
 The software is young and should thus be used with care in production
 environments.
 .
 Unlike OfflineIMAP It requires no IMAP server to be installed on the remote
 host. Moreover it never attempts to automatically resolve conflicts between
 incompatible mailbox statuses, it just notifies the user explaining how
 he can fix the problem.
 .
 Sync Mail Dir design is similar to the one of Maildirsync, but is more
 efficient in terms of CPU cycles and disk I/O.
