This is anecdotal retelling of your situation, with none of the supporting
evidence. For useful help you need to post configuration information and
relevant logs.
For example, how is the content filter specified? Is it just the transport
name or "transport:nexthop", ... But instead of teasing out configuration
settings one by one with follow-up messages, see:
