Hello! All mails store on server. How I can backup this emails for all users, for exmpl. for each month? And how I can restore this emails? Big thnks.
In ISPConfig 2, the email folders für maildir setups are inside the web tree. If you make a backup of the web tree (e.g. /var/www or /srv/www depending on your installation), then this backup includes already all emails. If you use mbox and not maildir, then all emails are in /var/mail/
