DAEMON_OPTIONS(`Name=MTA2500,Port=2500)
and rebuild

I have a centos & I use sendmail as mail server.
In sendmail.cf I had put an IP Address of relay server. & All mail is sending properly but My mail server administrator told me to put host name instead of IP address in SmartHost Ds in sendmail.cf & I done it but I cant send mail to anybody & I got an error –

451 4.4.1 reply: read error from smtp.sss.in.

Please anybody tell me How can I send mail to outside via my relay using host name & what should I do?
