Some Viruses and Worms scan pages in the browser cache for email
adresses. So they would find your honeypot adress if somebody who
happens to be infected views your page.

Two possible explanations:

1) People who are infected by viruses and worms are careless. Thus, they
are much more likely to install proxies, mail-relays, formmailers and
other programs without considering the consequences or even bothering to
configure them correctly.

2) Some viruses install trojans which act as open proxies.
