Then the Solutuion in the order it was sorted out.
Firstly with all these people's help i learnt about
logs to see for sendmail realted issues.
We reliased that it was a nslookup issue and after it
was sorted out we edited the sendmail.cf file to
lookup directly the host ie my exchange server and not
my DNS server.
So edited the /etc/nsswitch.conf file to query only
files and not DNS by just deleating the dns entry.
Restarted the sendmail by
/etc/init.d/sendmail stop
/etc/init.d/sendmail start
BINGO the mails were back to where it belonged.
Thanks again for all your help.
Regards
Sumedha
