Hi ALL...
Am working on a solution to backup maildir mailboxes using rsync.
All mailbox directories are mirrored on another machine.
I need advise regarding restore of the INBOX & SENT files from the backup.
For e.g , [1] Can I just copy "file-x-y-z" from /Maildir/cur to
restore it
on /Maildir/cur on the mailserver.
[2] Can I do same for SENT emails ?
Thanks
CoolAtt

But it can lead to duplicate mail, because the filename is not static, e.g. message status or keyword changes are reflected there. There had been a thread lastly about this topic (well, a minor bit differently); I restore the mails to a completely different folder and let the user pick the messages and re-file them into specific mailfolders. Others suggested to use a script to verify filename stem (before the colon), e.g. restore to tmp/, then check new/ and cur/, if there exists a file with the same stem. However, there had been said that there is a possible race condition, if the message flags are changed simultaneously.

When I delete the mail file from /Maildir/cur and restore it from the backup , I cannot see the body of the email when I view it (only the subject appears) I restored only a single mail file using scp: scp root at backup-host:/backup/vmail/coolatt/Maildir/cur/1264489757.P14232Q0M667471.ecs,S=628:2,S /home/vmail/coolatt/Maildir/cur/ Please help me.

If this does not help, try to change the stem of filename (before colon). I do not have a caching MUA and never (well, I did not often restored messages directly into the original mailbox) had a problem like that.
