[Evolution] Evolution appends @hostname to username

["Michael Guyver" <kenevel googlemail com>]

Hi there,

I'm trying to configure Evolution to operate over an SSH tunnel, so
I've entered the server address as localhost:1143. I've entered my
username as michael harrison somewhere net but evolution has appended
@localhost to it, resulting in the incorrect username
michael harrison somewhere net@localhost, which means the login fails.

How can I stop this happening please? I know there's nothing wrong
with the SSH tunnel as I have Thunderbird operating over it just fine.

Cheers

Michael
