handle tagged BAD [TOOBIG] server responses
some servers consider attempts to APPEND too big messages to be BAD
commands, rather than just NO-worthy ones. so just pretend that we did
in fact get a NO, and carry on.
this was tested with gmail. if we run into servers that don't send the
expected response code, we will need to relax the condition.
