It seems that I was the only member hit by this sudden avalanche of spam. I receive a large amount of spam each day as I have a commercial email address as well as a personal one but normally my filters throw about 95% of it into the Spam folder and then delete it 24 hours later. This came addressed to both identities that I have to use for email. Some was filtered out , about two-thirds - the rest arrived in my normal Inbox. this has never happened before. I have SpamBully version 3, Norton Anti-virus [updated Friday] and Microsoft Spam filter Beta version. In addition my ISP has spam filtering.
I do not use Thunderbird because I found it had no real spam learning mechanism - even items specifically pointed as spam came through. I do not use Mozilla as a browser as it is not compatible with my eBay selling activities - it will not allow me to use the eBay toolbar which verifies whether messages are spoofs or genuine - same, of course applies to Netscape which uses the same platforms. Thunderbird may be fine for people who have no commercial use of email.
I have never seen what the objection is to the function of Outlook Express - I send or receive about 2000 genuine emails a year and have difficulties with perhaps one a month.
