Depends - if you reckon you can get the offenders to change their mail
server behaviour, it's worth pointing out the fact that they're breaking the
RFCs. However, in the case where, like us, you're a minnow, and they're a
Big Company That Knows Best (e.g. att.com, wmg.com) and you just *know* you
won't be able to get them to change, then you'll probably have to allow the
offending domains to bypass your callout acl:

  deny  sender_domains = !${if exists{CONFDIR/local_non_verify}\
                             {CONFDIR/local_non_verify}\
                             {}}
        !verify = sender/callout=90s


And put all the offending domains into the CONFDIR/local_non_verify list.
