[lcd4linux] Config-Sample for the pop3-plugin?

[<An...@t-...>]

Hello List.

I try to use the pop3-plugin and dunno how i can get it to 
work. I sucessfully put in username and password in the 
pop3_plugin-Section:

Plugin Pop3 {
   server1 'pop.t-online.de'
   port1 110
   user1 'An...@t-...'
   password1 'hehehe'
}

and get back starting lcd4linux -vvv :

[POP3] 1 POP3 accounts have been succesfully defined

Now, how should the correspondenting widget should look like
that mysterius to me. Ive tried:

Widget Pop3 {
   class 'Text'
   expression POP3check
   width 5
   align 'R'
   update tack
}

Im sure it isnt true, since it didnt work and i also cant
imagine it will, but i really have no idea how that should
look.
Or am i on a totally false path that a widget is needed?

Thanks for an idea.

Regards,
Andreas
