I have 3 domains that I host, plus I have several Yahoo (disposable) addresses. All of my domains are hosted on the same physical server, but each has separate (virtual) mail servers. Is any of this a factor?
I'm trying to register my mail hosts - I entered 3 successfully. I added a 4th one too, and although *it* worked, it seemed to knock one of my already-registered addresses off the list. Is this a fault or a limitation?
