I'm in the process of enabling postscreen, and, just noticed started
getting these warnings today, after editing/adding postscreen
Jan 11 13:03:12 geko postfix/smtpd[5403]: warning: restriction
`check_sasl_access' ignored: no SASL support
Jan 11 13:03:54 geko postfix/smtpd[5403]: warning: restriction

Jan 11 13:04:39 geko postfix/smtpd[5403]: warning: restriction
`check_sasl_access' ignored: no SASL support
looking at log events for one of these, I see like[1]:
in my /etc/postfix/main.cf I have
# grep check_sasl_access main.cf
check_sasl_access hash:/etc/postfix/sasl_access
this was put 2 yrs ? ago, aiming to blocking compromised user account to
stop being used for spam
never had (or, noticed ??) these errors before
what did I screw up..? postconf [2]
