I believe it to be self evident that the source of the affliction that you are experiencing can be best described by the acronym: PEBKAC. Microsoft has nothing to do with it.
I know you are just trying to be funny, but some email programs do limited address verification before letting you hit send and warn you of probable problems (curiously Outlook Express is one of these...). However, at least the MS email programs have a curious kind of autocomplete which can lead to the user entering the recipient name rather than the email address (imagine using an email program which autocompletes email addresses, you get used to writing "postfix" every day and then hitting tab and it turns into "postfix-users@postfix.org", but today you hit some other key combo and you are left with just "postfix" on the TO line and you hit send without noticing - easily done I think?)
In general it's useful for machines to "do the right thing" and at least in my situation this means bouncing the email rather than delivering (I concede that others may prefer something else)
