[imp] Sending mail with wrong email-address

[Sven Pfeifer]

Hi folks,

i'm using IMP 3.2.1 as my mail application. Now i see that there is a problem
when sending mails outside my domain. If i send a mail to a non existing
mail-address, i get no error messages. Examinig an outgoung mail i found, that
mails are sent with the following "Sender:"-header:

    Sender: <my_webserver_username>@mydomain.com

TIA

   Sven
