As of 8.9, sendmail will refuse mail if the MAIL FROM: parameter has
an unresolvable domain (i.e., one that DNS, your local name service,
or special case rules in ruleset 3 cannot locate). If you want to
continue to accept such domains, e.g., because you are inside a
firewall that has only a limited view of the Internet host name space,
use
FEATURE(`accept_unresolvable_domains')
Were your other, SuSE/Mandrake, versions prior to 8.9?
