[imp] Sender without username part

[Stand H]

Hi all,

I can't get into my mailbox when someone send me an
email without the username part, eg. From: " Lonle"
<@domain.net>. After removing this email from my
inbox, I could get into my mailbox as normal. Is it
the problem with IMP/Horde? I use pop3 to get the
mail. I think it is not the problem with pop3 server
because I can the email using Outlook Express.

Some info:
Horde: 2.0
IMP: 3.0
PHP: 4.1

Thanks,

Stand
