Not Able To Send Mails With Huge Attachment

Dear All,

can any help me.

I am using Airtel Broadband - 256 Kbps

I have configured my email not Airtel (ashokkumarsn@lomead.co.in) in Miclosoft Outlook 2003

I am not able to send email attachment with huge size, say 10 mb or more.

Is that the limitation of broadband service provider or restrictions from my email service provider.

Any other solutions.

Need your reply urgently.
