Configure Cyrus-imapd

The cyrus-imapd system will have virtual hosting enabled, sieve scripts, quota's set to 10MB, auto creation (& auto subscription) of the mailbox with these folders (INBOX,sent-mail,drafts,spam,trash). Authentication of users will take place aganist the Mysql database via SASL using the saslauthd daemon.

• Create the configuration /etc/imapd.conf with the following content
