On an ISPConfig email server... What option do I need to turn on for the email server to maintain a copy of all emails for up to a year or more... So it always keeps a copy of emails.....
There is no such function in ispconfig. If you need such a function, you can e.g. write sieve or maildrop script for it?
As alternative you can e.g. create anwe mailbox for archiving emails and then add a redirect command for the emails in the custom rules field ov every mailbox. http://www.faqforge.com/linux/contr...-copys-of-incoming-emails-to-other-mailboxes/
