I think it would be fine to not send email on certain error conditions  
that could be used as a vector for spam, such as invalid signatures.   
OTOH, PQM should still clearly log exactly why such requests (merge or  
otherwise) are getting dropped.  It's been my experience that some  
silent failures are really silent in that they aren't included in the  
log output, or at least not in a way that you can ever match up the  
request with the logged information.
