Mrs. Brisby's patch for qmail-smtpd.c for username/password auth

[Martin Jespersen]

Does anyone know of any reason not to install this patch if the functionallity is 
kind-of-needed?

I mean does it affect performance for example?

I am no c-guru and the diff i didn't on patch and the original doesn't give me any 
hints to wethr or
not it is sane to use the patch...

the reason i ask is that it is listed so far down on the site that i thought it might 
not be seen as
a 'good' patch...

*feels a little stupid for asking this*

Regards

Martin
