fatal: parameter "smtpd_recipient_restrictions" in maillog

I am seeing this in my maillog:

fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit

However in my main.cf file I have this:

smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, check_relay_domains, reject_unauth_destination, reject

Can anyone explain what the problem is here please?


ok - I found it - it's referring to the setting in my master.cf - doh!
