PLEASE don't use HTML mail. Can we block it? (was: Re: nagios server performance)

hi all

Please do not use HTML formattet mail like the one below. It is ugly and 
unnessecary. Even though some email clients support it (and some - read 
Microsoft Outlook [express] defaults with it), it's still ugly and 
unnesseacary. Text is just as fine.

Perhaps someone administering the list could add a little filter with a reject 
message bouncing back to whoever sends this sort of messages?
