Help me understand SMTP server bounces and lockdown
I'm using Win 03 Server Pro and the bundled Virtual SMTP server. I'm storing email addresses in SQL Server and sending auto verification message using a 3rd party DLL (xp_smtp_sendmail) - not exchange server or MAPI client. I need to understand what happens when a user stores an invalid email address - well formed but invalid -
It would end up in the Badmail directory?
It will re-try until Expiration timeout setting?
On the lock down side of things...
This server functions as a web server (sits in Web Service Provider farm) and needs to provide outbound mail for the local SQL Server, ASP pages and the occastional direct email from the System Admin. Given that profile, what setting should i implement to for adaquate security?

As far as security (at the SMTP level at least) you should lock down the relay settings for the virtual server. Make sure the list for allow relay says "only the list below", and that the local server is the only one listed.
