Hello, I can't identify the cause of impossibility to relay emails through my Postifix mail gateway, from a Outlook express client.
>From mail log, I saw: postfix/smtpd[16988]: connect from unknown[xxx.yyy.www.zzz] postfix/smtpd[16988]: 7B98D75008D: client=unknown[xxx.yyy.www.zzz] postfix/cleanup[22797]: 7B98D75008D: message-id=<[EMAIL PROTECTED]> >From client side I get a pop-up window that points out problems with server communication or even network.. What it couuld be inferred from postfix log above? How could continue to investigate to get the cause of interruption? TIA, rocsca
