not able to Send mail due to Security Issue
Hi All,

I am trying to send a mail from my application through SMTP in solaris 9 but unable to send a mail.Same code is able to send mail in Windows.

As unix has more security,So as per me,it is due to security reason..

So please let me know what I need to do to send a mail properly.
what files i need to check and need to be modified to dissable the security..

Thanks in advance..

if you are having the problem on linux too, then send us errors from the linux machine. Otherwise, please post in the Solaris forum.
