replaced the MD5 implementation with the one of Solar Designer Until now, the sample code of RFC 1321 was used. It had an ugly license. Now we use the implementation of Solar Designer, which is in the Public Domain. http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5

meillo@118 38 The message size is defined as the number of octets, including

meillo@118 41 after receiving reply code 354 to the DATA command.
meillo@118 42
meillo@118 43 l_cnt (line count) covers '\r' characters which are not present in
meillo@118 44 masqmail's internal format. Dots are also not stuffed in the
