Gateway Timeout

I use MailWasher to "forward" spam on to SpamCop so I don't have to 
cut-and-paste-and-wait-7-seconds for every submission.

In the last three days, I have been unable to process any of my 
unreported saved spam, due to this error:

Gateway Timeout
The proxy server did not receive a timely response from the upstream server.
Reference #1.9072f9d1.1126908248.1e9a0a9

When I report a saved piece of spam, my browser sits there for about 10 
minutes, and then gives me this page. I get this effect among multiple 
browsers (Mozilla, Firefox, IE, Opera, Camino, etc.) and across multiple 
operating systems (WinXP, Win2003, MacOSX, MacOSx86, Linux, OpenBSD, 
etc.). I have also rebooted, and renewed IP addresses across all 
machines. I have not made use of any proxy server.

What's up??

TIA
