How do I set up Cyrus to store emails?

Set up a simple directory structure for Cyrus to store emails, owned by the cyrus user and group mail: The /var/spool/cyrus directory is the partition where Cyrus will store mail and must be allocated sufficient storage. The exact location can be configured in imapd.conf (5) in the partitions options.

How does Sendmail work with cyrusv2 Mailer?

This enables the cyrusv2 mailer for local mail delivery. This is a sendmail property that tells sendmail it’s talking to Cyrus. (Cyrus 3.x works with this property, despite the naming confusion.) Next, we run a script that takes the /etc/mail/sendmail.mc file and and prepares it for use by Sendmail.
