The maillog only has the line like:
May 12 11:20:14 email sm-mta[66223]: m4CFKEuB066223: [69.245.x.x] did not issue
MAIL/EXPN/VRFY/ETRN during connection to IPv4
which is the same thing i get when i do the telnet XXXX 25 from a machine
that's on the same network (that gets the 220)
May 12 11:20:52 email sm-mta[66314]: m4CFKfiJ066314: [10.0.60.60] did not issue
MAIL/EXPN/VRFY/ETRN during connection to IPv4
Is there something for the telnet daemon, or the sendmail daemon that restricts
telnet access to just the subnet its on? i.e 10.* network?
