Known bug!  The default templates actually need to be updated to not include
those urls, because the core doesn't know what those urls would be.  There is
machinery to allow for two levels of indirection so that, e.g. url-containing
templates could be defined in Postorius, and the core would fetch the on
demand, but that needs to be fleshed out a bit more (and will be in MM3.1).

It sounds like a Postfix problem, so cranking up Postfix logging is probably
going to be the most fruitful avenue.
