This is actually the relevant section of the docs, though it shows essentially
the same thing:


http://www.exim.org/exim-html-4.50/doc/html/spec_39.html


39.31 Callout verification

test whether a bounce message could be delivered to the sender address. The
following SMTP commands are sent:

HELO <smtp active host name>
MAIL FROM:<>
RCPT TO:<the address to be tested>
QUIT


******************************************

VRFY should be used, not RCPT TO:
