Hi,

I am using qmail on FreeBSD with ucspi and daemontools as decribed in LWQ
and everything is great...

There is one patch you need to implement on the FreeBSD kernel in order to
not suffer a buffer overflow in one of the function that qmail uses. This
buffer overflow will effectively replace the address for the MAIL FROM
command of outgoing smtp session with crap leading in email rejections from
remote smtp servers.

Note that this bug affects FreeBSD, but may also be present in other BSD
based TCP/IP implementations.

The file to patch is /usr/src/sys/net/if.c, the attached patch is against
the current RELENG_4 version.

Have fun with FreeBSD...


Patrick.
