I am going to say this agen, at the risk of offending the admins and getting my account suspended...
In this "ongoing email saga" (yes, that is the subject of a nearby thread), all of these posts about emails not getting through have something in common. Find that common thing, and our email problems will go away.
BTW, I had problems with gmail and aol. Sometimes the message would be sent and sometimes it wouldnt. Sometimes I would receive the message and sometimes I wouldnt. Then there was a 2 week stretch where NOBODY got my emails. I had to stop using my x10host email and go with another provider.
