Do you need Cyrus-sasl anymore?  Dovecot now comes with its own sasl.

I am working up a 
C7-Postfix/MYsql/Postfixadmin/Dovecot/Roundcube/Amavis-clamav howto.

So, sorry, I switched from Sendmail to Postfix some 6+ years ago.

I am actually doing this on Centos7-amrv7hl, but it will work on all C7 
arches.  It will take me a couple more weeks to finish, but will share 
with anyone that wants it now or more wants to help.
