[vchkpw] chkuser patch and mysql on different machine

[Dave Richardson - Lists]

I want to build a mail gateway to deny incoming SMTP for unknown virtual 
domain users by building it with the chkuser patch (correct patch name?).

I use MySQL for my user database on the mail server.

Can I hook the gateway (via VPN) to the user database on the mail server 
for the auth checks?? I haven't worked with the chkuser patch so this is 
very new ground for me.  

No, I'd rather not start replicating MySQL databases if I can help it. 
I want the gateway to save resources for scanning virii and stopping 
this Sobig crap.

Thanks in advance, Dave.
