[Tfug] Interesting mail statistic

[Choprboy]

Anybody notice changes in their mail servers over the last 2-3 weeks? I just 
did a summary and noticed a marked drop in connections from both blacklisted 
IP ranges and emails with viruses/executable attachments. Both blacklisted IP 
connections (known spammers) and email caught with viruses have dropped to 
25-30% of the volume of 6 weeks ago.

At the same time, the number of connection to my server forging HELO commands 
has more than doubled. The number of denied dynamic IP connections (about 
50/50 split between virus/worm and spam relay from what I can tell) has 
remained constant... Anybody see anything simillar?
