the three recipients could have been in one SMTP session (1 postfix msg ID), or in three SMTP session (3 postfix msg ID's). For the msg received, identify the postfix msg ID, and then look for that in maillog. If that msg ID was addressed to only the one recipient AND not rejected for the other two, then it was not SENT to postfix, so non-delivery is not postfix's responsibility. Then, see if the non-delivered recipients were rejected by postfix in separate SMTP sessions for this msg: egrep -i "[EMAIL PROTECTED]" /var/log/maillog If not rejected by postfix, the non-delivery is not postfix's problem.
