Hi list I got a imho weird problem with understanding the logs. We have an client that authenticates correctly which generates an id from postfix. If I grep this id through the logs I can see a logline with a message-id. But why there is no recipient?
<< Nov 5 05:26:44 213.196.149.XX postfix/smtpd[30553]: B93D2180036: client=unknown[188.119.245.XX], sasl_method=LOGIN, sasl_username=our_u...@example.com Nov 5 05:26:46 213.196.149.XX postfix/cleanup[30375]: B93D2180036: message-id=<000001cff8b0$b57dd950$20798bf0$@example.com> >> I cannot understand why we get the message-id without any recipient. Normally if I grep the postfix id from a login I can find a line with a to=<recipi...@example.com> I could understand if we only have the first line. That would mean for me that the client authenticated but did not send an email. But does the message-id not mean that DATA has been transmitted from client? But then there should be a RCPT TO or not?
