| I'm sorry, but if an MTA doesn't conform to the RFCs in too gross a way,

Rather than risk heaps of users getting really really unhappy and the
possibility of management getting rather upset I would rather put up with my
logs filled with errors during peak times for the time being (considering we
used to have every problem under the sun before using exim as a gatway for
our internal mail servers).

I received a response from the ISP and essentially they said they will not
be changing their MTAs just because they received a few complaints every
week (I assume from this that I am not the only person who has complained).

In a perfect world, all MTAs will completely conform to the relevant RFCs.
But in reality, they don't. It would be nice if exim would attempt delivery
using alternate routers / smarthosts rather than bouncing the messages on
the first error though (any chance of this making it ito v4??)
