Thank you.

My counter would be:

If VRFY has been disabled by many sites, and if both RCPT TO and VRFY get you
DNSBL'd for doing either of the verifications with foreign sources...

That leaves only 'internal' handshaking between 'friendly' servers. And, we're
back to VRFY, which was designed for that purpose.

Even if, as you suggest, VRFY would get us listed, clearly RCPT TO already gets
us listed and is, therefore, useless as coded.
