Sam, you're working too hard! You're trying to do the work of a whole
development team <grin!>. This has actually been possible for quite a
while. In submit.C, function getrcpts(...):
if (my_rcptinfo.errflag > 0)
{
const char *errmsg=my_rcptinfo.errmsgtext;
int l=atoi(errmsg);
if (l < 400 || l > 599) l=511;
mailfromerr(l, errmsg, 0);
}
If the number at the beginning of the string echoed by maildrop (or some
other MDA filter) is < 400 or > 599, or if there is no number there, the
error number return is set to 511. Otherwise, the user specified error is
returned to the requesting SMTP client.
I'll let this go now, but I had to figure out what goes on here :-)
Thanks to Dave Pratt for pointing me in the right direction.
