Kind of.  If an upstream filter (even one that runs earlier in the 
sequence but attached to the same MTA as opendmarc) rejects the message, 
the message will bounce.  The remaining filters don't get a chance to 
complete processing of the message.

So if you want opendmarc to handle the message, upstream filters must not 
reject it.
