Question about SPF email filtering

["Dye, Jan" <dyeja () MISSOURI EDU>]

I'm just curious to see how many of you have enabled SPF filtering on your email systems?

We recently enabled this, and the result is that we have many support tickets from users who no longer receive mail 
from rejected senders. These senders are legitimate, however, they have "bad" SPF records.

We're wondering how other institutions are handling this, and if SPF checking is really worth it.

If I've posted this on the wrong list, please let me know.

Thanks,
