I use EFA as a box between internet and Exchange so i have
reject_unverified_recipients into smtpd_recipient_restrictions so it checks in Exchange before accepting our email
In this way Echange doesnt make NDR

Now I enabled SQLGREY from EFA panel and I found that reject_unverified_recipients was removed from smtpd_recipient_restrictions substituting by check_policy_service inet:127.0.0.1:2501

If i try to manually add reject_unverified_recipients when i try to send me email in rcpt to: i get an error 451 4.3.5 server configuration error

It is not possible to have email verification and sqlgrey together ?

Can you share a snippet of your config?

It was my problem, the word is reject_unverified_recipient and not reject_unverified_recipients !

A notice, when you change GRAYLIST ON/OFF using configuration panel the script put a predefined string into configuration and reject_unverified_recipient is lost if someone added it

reject_unverified_recipient is a necessary word when EFA is used between internet and internal Exchange because it doesnt generate NDR
