Not sure u want to get mimedefang involved in this kind of thing ..
although it would be nice to have sendmail tell mimedefang this kind of
message, sothat mimedefang can be made aware of these "bad" ppl.
Sendmail can handle this independent of mimedefang, using the following
in sendmail.mc
-----
define(`confTO_HELO', `<time u want them to hang around>')dnl
-----
default is '5m' should be ok to set at '2m' or so, note to self .. check
rfc.
Ofc u need to be running sendmail for this to work .. but I'm sure
postfix or others have configs like this too.
