Hi Folks, I'm new on HowToForge and almost new on Ubuntu. I found here many information to set a AWS server on my own. I installed the DKIM patch and it's work great, but now I can't send mails. I had already problems sendig mails, but now are deeper. Some mails was sent and I tested my DKIM sign, but now I don't know what happend... ISPConfig version is 220.127.116.11p9 Ubuntu 14.04.4 LTS Yoy can see mail.log here: Code: May 1 20:55:17 dingalin postfix/smtpd: connect from unknown[18.104.22.168] May 1 20:55:18 dingalin postfix/smtpd: NOQUEUE: filter: RCPT from unknown[22.214.171.124]: <email@example.com>: Sender address triggers FILTER amavis:[127.0.0.1]:10026; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<[127.0.0.1]> May 1 20:55:18 dingalin postfix/smtpd: A7CD1606D7: client=unknown[126.96.36.199], sasl_method=PLAIN, firstname.lastname@example.org May 1 20:55:29 dingalin dovecot: imap-login: Login: user=<email@example.com>, method=PLAIN, rip=188.8.131.52, lip=172.31.20.52, mpid=3273, TLS, session=<gHdZnNAxmgDOhG1B> May 1 20:55:34 dingalin postfix/cleanup: A7CD1606D7: message-id=<firstname.lastname@example.org> May 1 20:55:34 dingalin postfix/qmgr: A7CD1606D7: from=<email@example.com>, size=12483, nrcpt=1 (queue active) May 1 20:55:34 dingalin postfix/qmgr: warning: connect to transport private/amavis: Connection refused May 1 20:55:34 dingalin postfix/error: A7CD1606D7: to=<firstname.lastname@example.org>, relay=none, delay=17, delays=16/0/0/0, dsn=4.3.0, status=deferred (mail transport unavailable) May 1 20:55:36 dingalin postfix/smtpd: disconnect from unknown[184.108.40.206] I already read many tutorials and forums with the same problem but I still stopped on that. Obviously the problem is "warning: connect to transport private/amavis: Connection refused" I have the same results from Thunderbird and SquirrelMail. The process completed succesfully, without errors, but the e.mail never leaves the queue I hope you can help me! Thank you very much and best regards from Argentina!
