[cobalt-users] How to delete mail through telnet?

["Adam Holt" <mediadezines@xxxxxxxxxxxxx>]

Hello, 
When I login via telnet, the server tells me I have mail,
I type in mail, and am shown the following:
"/var/spool/mail/admin": 1223 messages 1223 new
 
So, now I'd like to know how to delete all these messages??
 
Can someone tell me how to delete them in one big swoop?
 
Thanks
