To solve the security problem when routing mail to dynamic addresses, I'd
recommend to use TLS/SSL certificates instead of SMTP AUTH. You probably use
TLS anyway. Check

http://www.exim.org/exim-html-current/doc/html/spec_html/ch30.html

for the hosts_require_tls and tls_verify_certificates options.

Check the generic verify_* router options:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch15.html

These can also be inverted by prefixing them with "no_"
("no_verify_recipient"). You can then define a fall-through router that just
accepts (and has verify_only set).
