Godaddy India — mail server not working properly

Every month i m getting error send mails.
i tried to contact godaddy but couldnt get any specific reply.
always same reason that out cpanel detected spam.
But question is if i m sending max 30 mails in a month how can it detect spam.
but no answer later they said its cpanel issue which v r giving u free of cost with server so we dont know and cant support for that.
i will recommend not to buy server no support from godaddy.
