If you're a beginner you do not need such a complex system. Start small, such that you can actually learn what you're doing. When you're running an ISP or a huge freemail system like gmail, add complexity as may be required. http://www.postfix.org/BASIC_CONFIGURATION_README.html is a good starting point. > I've made some test, andthe previous oneshave gone well: > > 1) echo test | mail j...@example.org > 2) mutt -f /var/vmail/example.org/john/Maildir > 3) mutt -f imap://j...@example.org@localhost > 4) access by roundcube > 5) telnet localhost smtp > 6) openssl s_client -connect localhost:25 -starttls smtp You should know what each of those is actually testing. Most of those tests are not really showing you anything relevant to the $Subject line. > More than thetutorialI've installedshorewalland open/close > someports: snip > ACCEPT net $FW tcp 587 I don't use (and this list does not support!) shorewall, but this looks "open" ... > But the 587 nevertheless seems closed testing server by nmap: > > nmap -O 91.205.175.213 > > [..] > 587/tcp closed submission > [..] ... and this might be contradictory, or it might be another case of poor testing procedure? > Testing spam detection via swaks seem not work so fine: > > swaks --to j...@example.org --server 91.205.175.213 --data > /usr/share/doc/spamassassin/examples/sample-spam.txt > > it producesthis log (verbosity=4): Leave verbosity at normal. You do not / did not need all the extra garbage, which in fact seems to have caused you to overlook what you needed to see: > Oct 20 21:41:38 server postfix/submission/smtpd[3301]: connect > from server.sio4.org[91.205.175.213] So this ^^ says your $Subject is wrong, at least when testing from the host you used for your test. Looks like the same IP address, so most likely this was a bad/pointless test. > Oct 20 21:41:38 server postfix/submission/smtpd[3301]: > > server.sio4.org[91.205.175.213]: 530 5.7.0 Must issue a STARTTLS > command first Christoph has configured submission to require TLS, which is good.

If that's the case, check your shorewall documentation and go to a place which supports that software, which is a frontend to the Linux iptables(8) toolset. You might indeed have Postfix misconfiguration problems; likely so because your post indicates you don't really understand much about how it all should work. But you did not present any evidence of issues with which this list would be the place to go for help. If you do encounter Postfix problems later, please see this link, which was given in the list welcome message, before posting again: http://www.postfix.org/DEBUG_README.html#mail -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
