Sure, if the Spam-Hating software is buggy, then it will generate unnecessary garbage. If it works, however, the only fear you'll have is if your users are spamming. That should be taken care of by dealing with the spammer(s), rather than by taking the ostrich approach.

In the past I was targetted by an anti-spam attack against "eros net" (I forget their real domain) because I'm listed in one of the nameserver records for EROS.COM which is not at all related to "eros net". I suppose this sort of human screw up may not happen depending on how the tool is written. In any event, sometimes people who receive email they asked for (i.e. entering their email address on a web form which explicitly said they would be receiving said mail) initiate anti-spam attacks because they forgot they asked for the mail.
