It seemed very similar to the spam I receive usually, so I clicked on Delete... but instead of being deleted, it just made the browser tab unusable. Tested on Windows Vista Ultimate Service Pack 2, with the following browsers: -Google Chrome: IMP tab becomes unusable, all links rendered ineffectual. The only escape is to use the Horde menu if you have it, or hit the browser "Back" button. -Internet Explorer: Cannot use it. Keeps telling me that my browser has changed since the start of my session, so I must log in again... and again.. and again... despite already having logged out in every browser. -Mozilla Firefox: IMP tab becomes unusable, no matter where I click it opens a tab to the spam website - not even Log out works. The only escape is to use the Horde menu if you have it, or hit the browser "Back" button. Having "NoScript" and using it to block the webmail doesn't prevent the issue from happening. -Safari: IMP tab becomes unusable, no matter where I click it opens a windows to the spam website - not even Log out works. The only escape is to use the Horde menu if you have it, or hit the browser "Back" button. -Opera: The only one to work all right - the one which allowed me to save the message source.

This rather sounds to me like your webmail system might have get hacked. If you really use IMP 4.2, I wouldn't be too surprised, since it's ages old and has seen many, also security, fixes since then.
