Hello!

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 name.com does not support PTR).
Address: 134.209.229.135
Message in syslog is following:

Code: Select all


Mar 25 19:45:40 mx37clinic postfix/smtp[19841]: A1824FEA2F: to=<[email protected]>, relay=mx00.emig.gmx.net[212.227.15.9]:25, delay=1232, delays=1232/0.01/0.06/0, dsn=4.0.0, status=deferred (host mx00.emig.gmx.net[212.227.15.9] refused to talk to me: 554-gmx.net (mxgmx014) Nemesis ESMTP Service not available 554-No SMTP service 554-IP address is black listed. 554 For explanation visit https://postmaster.gmx.net/en/error-messages?ip=134.209.229.135&c=bip)

What else to see and configure?
Thanks

It looks like you've already visited https://spfbl.net/en/delist/ and completed the removal process. Any cached listings should be removed within 24 hours.

Yes, thank you.
SPFBL removed quckly but removing from web.de and gmx.at took some time.
