[gentoo-user] cyrus-sasl necessary with localhost webmail?

[Grant]

I recently switched from Thunderbird to Roundcube (highly
recommended), switched to the non-SSL courier daemon, and plugged the
firewall hole since courier resides on the same system as my web
server.  Do I still need cyrus-sasl or will a webmail client
authenticate directly with courier?

I have authmodulelist="authshadow" in /etc/courier/authlib/authdaemonrc.
