Oh, thanks a lot for your detailed explanation. 

That's exactly the kind of info I need. We all know that "anything could 
happen". Once I asked how to use sendmail as the mail server so people 
can send me emails to me, to my account of my own domain, and the 
response was overwhelmingly: DON"T, then followed by "anything could 
happen", without explaining what actually could happen ---

Your detailed explanation really helped me understand the situation and 
complexity of the issue.

This is only for my personal use, and I'll turn it off once I'm done. 
I.e., I care more about *can* it be done part, not much on the part of 
"*should* it be done".

thanks again
