I'm experiencing some trouble with a single recipient because his mail server refuse my email.
This is the error reply:
SMTP error from remote mail server after RCPT TO:<email@example.com>: 554 5.7.1 Service unavailable; Client host [51.255.xxx.xxx] blocked using multi.uribl.com; 127.0.0.1 -> Query Refused. See http://uribl.com/refused.shtml for more information [Your DNS IP:89.119.xxx.xxx]
I read the linked page http://uribl.com/refused.shtml but my server ip is not listed in this list, what should I do?
