Viruses on Navy computers, i.e. I’m paying to get spammed

It looks like the Navy needs to update their virus software as they have a machine trying to send me spam:

Feb 20 21:37:39 linux sendmail[6685]: NOQUEUE: connect from
pacfc.fleet.navy.mil [205.56.145.37]
Feb 20 21:37:48 linux sendmail[6685]: k1L5bda1006685: ruleset=check_rcpt,
arg1=, relay=pacfc.fleet.navy.mil [205.56.145.37],
reject=550 5.7.1 ... Relaying denied

Can I send the Navy a bill for having to deal with their virus infected computer? I’m glad my tax dollars are hard at work sending me spam.
