please help me ...
i have a Zimbra email server running with this backup script
this email server have transaction about 5000 email/day.
i have one special email account (firstname.lastname@example.org) for backup purpose, all ingoing and outgoing email always auto forward into this email account.
then i have one linux box, installed with Thunderb*rd to download & delete from server all email from email@example.com and archive it daily into separated daily folder. (for decrease the size of backup file)
Now 1 backup file already got 32GB (compress to tar file). And Thunderb*rd seems got it's limitation (can not download email again, it always said "full") .
Can i download & delete all email from account firstname.lastname@example.org (daily), then make this download readable to email client like Thunderb*rd/Kma*l (for the purpose of recover deleted email or for "my boss purpose" or some kind like that) with some "command line / script" ?
so the result is:
1. downloaded email from email@example.com got daily name like example: "YYYYMMDD" 20130517 for May 17 2013.
2. firstname.lastname@example.org always empty everyday after downloaded.
3. if got something to restore or see, i can copy this daily backup file into an email client.
my old email using Qma*l, the backup method for download & delete this email@example.com only rename the "maildir" into different name two times a week, and copy that file into another computer.
thanks for any help
sorry for my english
