Hmm... almost there I think, except the way return addresses are generated "infpsyk-request@.melon.dk". I have no idea where the extra "." comes from, has anyone experienced this kind of error before??

The relevant part of the maillog is below, please CC any replies as I'm not on the list yet.

Thanks, Jacob
