Recently I noticed that our mail server is black listed by vote.drbl.gremlin.ru
Following the instructions at http://gremlin.ru/soft/drbl/en/faq.html#howtogetout I did the following
> host -t any 188.8.131.52.work.drbl.gremlin.ru
184.108.40.206.work.drbl.gremlin.ru descriptive text "gremlin:Spamtrap hit"
220.127.116.11.work.drbl.gremlin.ru has address 127.0.0.2
> host -t any 18.104.22.168.vote.drbl.gremlin.ru
22.214.171.124.vote.drbl.gremlin.ru descriptive text "Spamtrap hit"
126.96.36.199.vote.drbl.gremlin.ru has address 127.0.0.2
> host -t soa vote.drbl.gremlin.ru
vote.drbl.gremlin.ru has SOA record ns.gremlin.ru. drbl-79f8y6.gremlin.ru. 1486889337 10800 1800 604800 86400
I figured out, the postmaster address here is email@example.com. I sent a request to re-test our mail server, because recently we fixed some spam issues we had, but it was rejected with message
(host mail.gremlin.ru[188.8.131.52] said: 451-Rejected: 184.108.40.206 is blacklisted at vote.drbl.gremlin.ru 451 Spamtrap hit (in reply to RCPT TO command))
Do you have any suggestion how to have our IP delisted from this dnsbl ?
