"xyz.com" being the customer's domain, different for each site?  Or your 
domain, the same for all sites?

In the documentation for Mailtraq, or Windows-based mailserver, we advise 
putting in all three.  But in practice on the Raq I just let it do it's 
thing automatically (which is to add the domain name without the host-name, 
and also the IP#), and it seems to work fine.

However, this field is only for domains that will be SENDING mail through 
the RaQ, and is quite insecure behavior since anyone can spoof anyone's 
return address.

I'd suggest you tell your customers to use their ISPs server for outgoing 
mail, or install POP before SMTP.

When you check the "Receive mail for domain" box when setting up or 
changing a domain configuration, the Raq will do everything it needs to do 
to receive mail for a domain.

I just let my RaQ fill this in automatically; I never touch it.

The reason to do it is in case mail actuall has an address or return 
address such as:

jeff@xxxxxxxxxxxxx
jeff@xxxxxxxxxxxxxxxxx
jeff@xxxxxxxxxxxxxx

And then of course there's another varient you should allow for if you're 
really covering all bases:  jeff@[123.122.121.22].

Sure.  Make your user something like john123, and alias him to 
john@xxxxxxxxxx and webmaster@xxxxxxxxxxx
