... and the carriers communicate this to their users and those to their
contactors - so everyone is to be informed, what message size must not
be exceeded - if you don't want it back ;-)

But there are no alien relays in a mails path, so every involved person
knows what is allowed by that "closed system" ? Any other "random
destination" should be only packet switching (situation in Europe) ...

And I trust that a smart relay server looks up message sizes and drop
all exceeding his limit before reassembling them ...

No problems with spacious mails here ...
