I thnk that they have a sort of unusual configuration, I had an headache configuring all for the forum to work and sometimes the PHP email doesn't work (you can see the error appear) so I've to switch to the smtp server which has bandwidth limitation ... But I think it's better than the old one which was out of order a lot of times (even if they made manteinance during the night, there in the united states, exactly when I'm online...)
