Every time I do a full system restore it causes the mail client (Thunderbird) to download all the email from the server again, causing duplicates, triplicates, etc and increasing the clients mail box size exponentially.
Is there a setting on Dovcot to prevent this, as I’ve checked the client software settings and I can’t find any thing to correct this.
[root@www ~]# find /etc/dovecot | xargs grep mail_location
/etc/dovecot/conf.d/10-mail.conf:# path given in the mail_location setting.
/etc/dovecot/conf.d/10-mail.conf:# mail_location = maildir:~/Maildir
/etc/dovecot/conf.d/10-mail.conf:# mail_location = mbox:~/mail:INBOX=/var/mail/%u
/etc/dovecot/conf.d/10-mail.conf:# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
/etc/dovecot/conf.d/10-mail.conf:#mail_location =
/etc/dovecot/conf.d/10-mail.conf:mail_location = maildir:~/Maildir:INDEX=/var/lib/dovecot-virtualmin/index/%u:CONTROL=/var/lib/dovecot-virtualmin/control/%u
/etc/dovecot/conf.d/10-mail.conf:# explicitly, ie. mail_location does nothing unless you have a namespace
/etc/dovecot/conf.d/10-mail.conf: # mail_location, which is also the default for it.
