POstfix can suppress the STARTTLS by client IP address.
Example with table inlined in main.cf:
/etc/postfix/main.cf:
smtpd_discard_ehlo_keyword_address_maps = cidr:{
{192.168.3.4 starttls}}
Example with table in separate file:
/etc/postfix/main.cf:
smtpd_discard_ehlo_keyword_address_maps =
cidr:/etc/postfix/smtpd_discard_ehlo
/etc/postfix/smtpd_discard_ehlo:
192.168.3.4 starttls
