Hi all, a user of my forum has emailed me to say that when they tryto post, they get a message stating along the lines of...

The ISP (6 *******) has BLACKLISTED as it has been connected with spam words in it's emails,

24 hour blacklist.


Could someone explain what this is? and can I remove it, please? Because nothing is showing in my admin control.


PS. this is a trusted member that i know will not send spam.


Many Thanks.
