As previously mentioned greylisting is coming to all 34SP.com accounts. Read my previous post here if your not sure what greylisting is exactly.
Whilst we are mailing all users in advance of their server being enabled we do realise that some people are experiencing large levels of spam and are eager to get started ASAP.
To this end greylisting functionality is now installed on all personal hosting servers. Actual dates for the service going live have yet to be decided. If you want to get greylisting running on your account today, just drop us an email at the usual email@example.com address. We will be happy to enable your account in advance of the official activation date.
