Installed a mail server recently. For several days I tried to force the server to send letters to Inbox instead of Junk. Some mails came to inbox but other to Junk.
But today I discovered that the server was blacklisted.
DKIM, SPF are configured, the reverse zone was configured yesterday with DigitalOcean service (the registrar does not support PTR).
Message in syslog is following:

Code: Select all

Mar 25 19:45:40 mx37clinic postfix/smtp[19841]: A1824FEA2F: to=<[email protected]>,[]:25, delay=1232, delays=1232/0.01/0.06/0, dsn=4.0.0, status=deferred (host[] refused to talk to me: (mxgmx014) Nemesis ESMTP Service not available 554-No SMTP service 554-IP address is black listed. 554 For explanation visit

What else to see and configure?

It looks like you've already visited and completed the removal process. Any cached listings should be removed within 24 hours.
