Hi i've had ISPconfig working for my website since January but i still cannot figure out the mail side of things. I've followed the tutorial to the letter on here, and have tried various DNS entries with my registrars but i can still not receive any email. I've changed a few things and now i get this error 5.1.2 Bad destination host 'DNS Hard Error'. I've looked this up and it is supposed to be an A-record problem but my domain has an a-record and i can see the sites perfectly well. I'm now stumped.
