Subject: Help Regarding qmail-smtpd



hi,

  i'm running qmail-smtpd, when somebody connects to
port 25 and issues the following commands

 helo 220 server.com
 mail from: <abc@xxxxxxxxxxxxx>
 #i get a response saying
 250 ok

<p>  this is dangerous as people could assume false
identities and send mails. is there any way by which
qmail can prevent this from happening like doing a
reverse dns lookup or so.

<p>  Any info on this issue would be very helpful.
Expecting your reply and thanks for the help in
advance

<p><p>Rgds,
ashok
