[cobalt-users] How do cobalts still relay for IPs with no PTRs ?

["Fragga" <fragga@xxxxxxxxxxxx>]

hello,

this is not directly related to cobalts but i have a raq 4 and a standard
redhat box, the raqs can cope with relaying mail for IPs in their
/mail/access database even if those IPs dont have valid PTR Records whereas
this standard Red Hat box wont relay to exactly the same IP because it
doesnt have a PTR. all access database, local host names, etc etc are all
set up correctly. Can anyone shed any light on a config option i need to
change to maybe "ignore" IPs with no PTR which is seems cobalts do ?

kind regards
