The mail server I manage is clean according to 92 blacklists checked by MXToolbox.
But ...
host mx.ecentral.com.cust.b.hostedemail.com[64.98.36.4] refused to talk to me: 421 4.7.1 Service unavailable; Client host [My Server IP] blocked using tms.urbl.hostedemail.com; Your IP has been sending too much spam
How does one get off of this list? What puts one on their list but not on any of the ones with more obvious rules? Is hostedemail.com some kind of rogue provider?
Thanks!
hostedemail.com is used by OpenSRS providing email hosting service and it's not a blacklist directory. You don't have to worry you have to wait for couple of days while your IP will be refreshed accross all mailservers and dns globally.
