Hello, It looks like there is difference in postfix implementation of milter protocol regarding adding and deleting recipients compared to sendmail.
The following results in one final recipient on sendmail but no recipients on postfix while still logging nrcpt=2 del_rcpt "<em...@otherdomain.com>" add_rcpt "al...@domain.com" del_rcpt "<al...@domain.com>" add_rcpt "al...@domain.com" Jun 28 16:15:00 server postfix/smtpd[264815]: connect from server.local[127.0.0.1] Jun 28 16:15:14 server postfix/smtpd[264815]: 49vrhL14pvzBGTn: client=server.local[127.0.0.1] Jun 28 16:15:21 server postfix/cleanup[264963]: 49vrhL14pvzBGTn: message-id=<49vrhL14pvzBGTn@server.local> Jun 28 16:15:21 server postfix/qmgr[264819]: 49vrhL14pvzBGTn: from=< sen...@domain.com>, size=378, nrcpt=2 (queue active) Jun 28 16:15:21 server postfix/qmgr[264819]: 49vrhL14pvzBGTn: removed Jun 28 16:15:22 server postfix/smtpd[264815]: disconnect from server.local[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 >From what I understand the duplicate filter suppresses the address. Is this desired behavior? Thanks -- Mehmet
