Hello, I have a system with a few local users where some of them are configured for forwarding all incoming messages to external addresses via the use of .forward.
One of those users forwards mail to an hotmail.com address. When mail is delivered to this address this is what happens: > Oct 2 13:50:40 zed postfix/smtpd[1078]: connect from x.y.z[145.238.xx.xx] > Oct 2 13:50:40 zed postfix/smtpd[1078]: 5721C60DF: > client=x.y.z[145.238.xx.xx], sasl_method=PLAIN, sasl_username=d > Oct 2 13:50:40 zed postfix/cleanup[1070]: 5721C60DF: > message-id=<542d5832.2020...@grinta.net> > Oct 2 13:50:40 zed postfix/qmgr[23328]: 5721C60DF: from=<d...@grinta.net>, > size=614, nrcpt=1 (queue active) > Oct 2 13:50:40 zed postfix/cleanup[1070]: 6354160E2: > message-id=<542d5832.2020...@grinta.net> > Oct 2 13:50:40 zed postfix/local[1071]: 5721C60DF: to=<r...@grinta.net>, > relay=local, delay=0.07, delays=0.07/0/0/0, dsn=2.0.0, status=sent (forwarded > as 6354160E2) > Oct 2 13:50:40 zed postfix/qmgr[23328]: 6354160E2: from=<d...@grinta.net>, > size=741, nrcpt=1 (queue active) > Oct 2 13:50:40 zed postfix/qmgr[23328]: 5721C60DF: removed > Oct 2 13:50:40 zed postfix/smtpd[1078]: disconnect from x.y.z[145.238.xx.xx] > Oct 2 13:50:42 zed postfix/smtp[1080]: 6354160E2: to=<r...@hotmail.it>, > orig_to=<r...@grinta.net>, relay=mx3.hotmail.com[65.55.92.184]:25, delay=1.9, > delays=0/0.01/0.32/1.6, dsn=2.0.0, status=sent (250 > <542d5832.2020...@grinta.net> Queued mail for delivery) > Oct 2 13:50:42 zed postfix/qmgr[23328]: 6354160E2: removed > Oct 2 13:50:58 zed postfix/smtpd[1063]: connect from > bay004-omc1s27.hotmail.com[65.54.190.38] > Oct 2 13:50:59 zed postfix/smtpd[1063]: NOQUEUE: reject: RCPT from > bay004-omc1s27.hotmail.com[65.54.190.38]: 450 4.1.8 > <account-security-nore...@account.microsoft.com>: Sender address rejected: > Domain not found; from=<account-security-nore...@account.microsoft.com> > to=<r...@grinta.net> proto=ESMTP helo=<BAY004-OMC1S27.hotmail.com> > Oct 2 13:50:59 zed postfix/smtpd[1063]: disconnect from > bay004-omc1s27.hotmail.com[65.54.190.38] with minimum editing to prevent disclosing email addresses and clients, and where the last email rcpt attemt is repeated a few times. So, it seems that hotmail is trying to send something to the forwarded address, but in a weird way, which seems to be correctly rejected by my Postfix server. Is anyone else observing something similar? Should I do something about it? Thanks. Cheers, Daniele
