Spam statistics for utx@penguin.cz

I use my permanent e-mail address for about 5 years. It's used daily for GNU/Linux development and personal purposes. Now it is heavily attacked by spamers and virus owners.

Here is the statistics of deleted junk mails:

" cat <Note: Viruses are catched by attachment file name suffix rules, spams are catched by SpamAssassin, false bounces are catched by manual set of rules, mails with spam level ≥9 are blocked before delivery and are not included in this statistics.

Generated: $(date "+%Y-%m-%d %H:%M:%S %Z")

Summary: Once in the past, e-mail was the communication media. Now it is playground of spamers and virus owners. Even in late Saturday night, I need to wait only three minutes for next spam. E-mail is dead.
