Your SMTP server refuses to let you send based on your 'sender', i.e., the email-adress 'email@localdomain.com'. Usually, mailserver are set up to not care about that, so your mailserver is set up rather unusually. It probably only allows a certain from-domain, and that's not the domain you are using. So, you need to change your sendmail config to allow the domain you are using, or change it in some other way. The standard way is to allow only deliveries FROM the local network or TO the local domains.

im using sendmail as MTA

Oh, you like to live dangerously, huh? :)
