Hello everyone, I was using smtpd(8) (static IP and FQDN resolving direct and reverse) for a year without problems. Today sending from my server (from the same address I'm using now) to gmail and hotmail they answered the following (MAILER-DAEMON answer). Sending to gmail addresses: *@gmail.com: 550-5.7.1 [185.37.212.61] The IP you're using to send mail is not authorized to send email directly to our servers. Please use the SMTP relay at your service provider instead. Learn more at https://support.google.com/mail/?p=NotAuthorizedError e1si6736354wra.236 - gsmtp Sending to hotmail: *@hotmail.com: 550 DY-001 (SNT004-MC3F42) Unfortunately, messages from 185.37.212.61 weren't sent. Please contact your Internet service provider. You can tell them that Hotmail does not relay dynamically-assigned IP ranges. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. On the hotmail link above the explanaition for code DY-001 is: Mail rejected by Outlook.com for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP email to an Internet mail server. If you are not an email/network admin please contact your Email/Internet Service Provider for help. http://www.spamhaus.org maintains lists of dynamic and residential IP addresses. It doesn't happen with yahoo. I visited spamhaus.org site and found out my IP is included in a list called PBL that, as they explain is not a spammers list, it just includes dynamic and "non mail server IP ranges". Does someone here know what is "non mail server IP ranges" about? Or, how could my static IP could be taken as dynamic (some DNS faliure at my ISP end?).
