I was surprised that a value of 0 didn't completely disable this check.
So I changed src/transports/smtp.c:

-if (max_received_linelength > ob->message_linelength_limit)
+if (ob->message_linelength_limit > 0 && max_received_linelength > ob->message_linelength_limit)

and "set message_linelength_limit = 0" on all of my systems, which is what
I would have liked to see as Exim's default.

I see the good intention of enforcing RFCs, but it should be limited to
things that really make sense and not enforce otherworldly limits. And to
which - for good reason - no other software sticks.
