Hi,
is it possible to disable sendmail's DNS checks for certain users? In
particular, some of our users connect via an ISP who does not seem to
have forward DNS entries. So sendmail rejects those connections with a
'possibly forged' error. We also use require_rdns. Can I fine tune those
two settings?
thanks

# single IP address
connect:aaa.bbb.ccc.ddd OK
# */24 net
connect:eee.fff.ggg OK
# */16 net
connect:hhh.iii OK

Does this work only for IPs, or for domains as well? And to avoid

confusion. Will the above settings enable relaying from those domains as
well? We wouldn't want that...
