Hi Martin, Thanks for the quick response. There's no specific domains, and perhaps this is something that other customers may be interested in learning more about, but generally, are there any filters that you are applying, that your customers wouldn't know about ?

Also, quite a few spammers nowadays use other peoples email address's as the 'from' address so sometimes other people have their email address's on blacklists because of that, what blacklists do you refer to please?
