crappy implementations.
They need to just get over it and do the right thing.
There is one certainty about the length of lines, headers, parameters,
etc.: None of them will be any longer than the message as a whole.
If you have managed to read the message so you can parse it, you should
be able to handle any piece of it without imposing length constraints
that are not imposed by the syntax.
Of course, in certain cases something may exceed some other
uncontrollable bound on another part of the system. E.g. If your MESSAGE
is being gatewayed to SMS which imposes its own limit on how long the
content can be. But that is a different sort of a problem than an ALG
barfing on the message.
