we are using this ACL


  deny  sender_domains  = ! +no_sender_ver_domains
        hosts           = ! +no_callout_hosts
        ! verify        = sender/callout/callout_defer_ok


and replaced the line
  require verify        = sender/callout/callout_defer_ok


no_sender_ver_domains is a domainlist of the domains,
we don't want a callout for and no_callout_hosts is
a list of hosts for the same.
All other have to be checked.
