You require that remote host accepts random mailboxes, or smtp session
with any of their MX is longer than 40s, thus denying normal sites which

Why Postmaster message - maybe times ago postmaster calluot has been
made and cached, now run " exim_tidydb /var/spool/mail callout "
After that do the smtp session from exim -bhc and report back
