Of course. All relay operators have the right to protect themselves. 
 From trojans etc or spam generators.  This is why you can set up tor to 
provide its service on only certain ports.

But destination port blocking is a more difficult to approve of.

Obviously,  if you block port 25 traffic completely then all (usual, but 
not always, as it can be set up to another port) smtp will be blocked.. 
spammers & the rest of us included.

Now I used smtp (secure - not port 25) to deliver this email. Should you 
block this?

If so what about port 80?

I hate spam... but I've learned to live with it and so I use a spam 
filter. Thats the best way..

At the end of the day its YOUR relay .. as long as tor clients can find 
a good few routes from amongst all the relays out there, thats all that 
is needed.
