[Full-Disclosure] SMTP Spam Attempt?

[Michael Thompson]

For the past hour I have just watched over 200 dialup machines from all 
over the world attemp to connect to my Mailserver

They were all rejected like the following
Jan 19 09:05:07 polaris postfix/smtpd[24494]: warning: Illegal address 
syntax from host195-202.pool82191.interbusiness.it[82.191.202.195] in 
MAIL command: @

This lasted for about a hour. All I can think of is that I was picked on 
by some script/virus/Trojan looking to spam.

Any Views?
