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 126.96.36.199p9 Ubuntu 14.04.4 LTS Yoy can see mail.log here: Code: May 1 20:55:17 dingalin postfix/smtpd: connect from unknown[188.8.131.52] May 1 20:55:18 dingalin postfix/smtpd: NOQUEUE: filter: RCPT from unknown[184.108.40.206]: <[email protected][email protected][email protected][email protected][email protected][email protected][email protected][email protected] 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!
