SMTP transports by default verify that the destination is theoretically
reachable (DNS exists) but do nothing to speak SMTP.
In your RCPT ACL, you should have a line about "require verify =
recipient". Double-check that all mail to *remote*/external is handled
before that, and use "require verify = recipient/callout".
Do *not* do recipient callouts for mail to outside your domain -- double
SMTP connections for every mail you send out are likely to be frowned
upon. In the default config, the "require verify = recipient" check
comes *after* the "relay not permitted" logic; if you're using something
like the default, you should be safe to just add the "/callout".
