To me though IP address checking will not be sufficient now or in the
future. You should be required to give the SMTP server a password.
Otherwise the viruses will then locate your ISP settings and start
sending viruses via the ISP SMTP server. Hopefully your email
software will have your password securely encrypted.

That said I feel that ISP email software should start having virus
deletion in place on incoming email along with limits on qty of emails
which can be sent. Ie 100 per hour ought to be sufficient for anyone
but an MVP. <smile> And if you start sending viruses in your email
your ability to send emails is frozen until you contact your ISP.

But then blat will likely be changed. It shouldn't take too much to
add the userid and encrypted password parameters.

I'd go directly from VBA in Access anyhow. Presumably going directly
to the WinSock via API calls? This way you have complete control and
store all the settings within your product.

FWIW I have some TCP/IP VB URLs at my website.
