Sendmail uses the function finduser in recipient.c

This is a realy far fetched attamept, but..
1. if the username contains '\0' then sendmail will not find it
2. if username is longer then MAXNAME (=256, unless chaned)
3. there is also a worning in the code saying
/* warning -- finduser may trash buf */
pw = finduser(buf, &fuzzy);
where buf in finduser is the name to match against.
