Re: Failing to read new mail

[Richard Stallman]

    Could it be the 256Mb buffer size limit?  Even with an 88 Mb RMAIL
    file, maybe something like multi-byte encoding or the decompression of
    an attachment could push it over the limit.  Maybe (point) in

     (rmail-decode-region start (point) mime-charset)

What would happen, in such a case, is an error from whichever
primitive tries to make the buffer too big.  If some bug failed to
detect that, (point) would return a small number; it has no code to
detect overflow.
