Installing Cyrus IMAPd on FreeBSD involves installing the package, configuring /usr/local/etc/imapd.conf and /usr/local/etc/cyrus.conf, initializing the mail spool, and enabling the service in /etc/rc.conf. Common versions include cyrus-imapd312 or cyrus-imapd25, with saslauthd required for authentication.

2. Configuration
Create/Edit Configs: Copy sample configurations from /usr/local/etc/cyrus.conf.sample and /usr/local/etc/imapd.conf.sample to /usr/local/etc/.
Set Mail Spool: Modify /usr/local/etc/imapd.conf to set configdirectory, partition-default, and other necessary parameters.
Create Spool: Run the following to prepare the spool directories:
bash
/usr/local/cyrus/sbin/mkimap
Fix Permissions: Ensure the cyrus user owns the directories:
bash
chown -R cyrus:cyrus /var/imap
chown -R cyrus:cyrus /var/spool/imap

3. Setup Authentication (saslauthd) 
To use system users (PAM/passwd) for mail authentication:
Add saslauthd_enable="YES" to /etc/rc.conf.
Start saslauthd: service saslauthd start.
Ensure pwcheck_method: saslauthd is set in /usr/local/etc/imapd.conf.

Key Considerations
Upgrading: When upgrading, use cyr_info conf-lint to check for deprecated configuration options.
BDB Backend: If using BerkeleyDB (BDB), build the port with BDB support enabled, though switching to alternatives is recommended.
Virtual Users: For non-system users, configure saslauthd to use LDAP or a separate SQL database.
