Can't create mail account using AppleScript

Hi

I am trying to create new mail account (POP) using Apple script "Create New Mail Account.scpt" which is in "/Library/Scripts/Mail Scripts".

by passing commands like this.

script as follows:

tell application "Mail"

make new pop account with properties {name:"mymail" username:"myun" server name :"pop.xxx.xxx" password: "mypwd" full name : "myname" email addresses"{"myemail.gg.com"}}

Somehow it is not creating account, and getting back response as "Account Creation failed".

Can anyone advice how to resolve this.

Thanks in advance.
