Hello, I set up Relayhost for SparkPost on ispConfig mail server, Sending domain on SparkPost, opended port 587 on the firewall and DNS records. When I try to send I get this error:The mail system <[email protected]>: host smtp.sparkpostmail.com[35.163.252.178] said: 550 5.7.1 relaying denied (in reply to RCPT TO command) Reporting-MTA: dns; web.zix.is X-Postfix-Queue-ID: 664FE2192A X-Postfix-Sender: rfc822; [email protected] Arrival-Date: Mon, 29 May 2017 17:32:26 +0000 (UTC) Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822;[email protected] Action: failed Status: 5.7.1 Remote-MTA: dns; smtp.sparkpostmail.com Diagnostic-Code: smtp; 550 5.7.1 relaying denied Is the problem names on server web.zix.is / mail.zix.is ? I'm using mail.zix.is in SendingDomain on SparkPost. Should I use DKIM record from Sparkpost or the one ispConfig generates in the DNS ? How to fix ?
@ahrasis Thanks for your replay. I have fulfilled all on the link you posted. When looking on main.cf that ispConfig makes and SparkPost recommended setup there seems to be some missing lines: https://www.sparkpost.com/docs/integrations/postfix/
