Gack...  spend more time in the `bat` book...  Don't touch anything in
/usr/share/sendmail...

1) Add this to /etc/mail/sendmail.mc
   define(`confUSERDB_SPEC', `/etc/mail/userdb')dnl

2) `makemap btree /etc/mail/userdb < /etc/mail/userdb`

3) `sendmailconfig`

4) `/etc/init.d/sendmail reload`

Can't tell without know what your mods were !  Also, if you're using
masquerading/genericstable, that impacts userdb support...

If you're doing new work, I'd suggest moving from userdb to
genericstable - has much more flexability.

I forgot to mention an important fact in the 1.3.67 announcement. In order to
get a fully working kernel, you have to follow the steps below:
 - Walk around your computer widdershins 3 times, chanting "Linus is
   overworked, and he makes lousy patches, but we love him anyway". Get
   your spuouse to do this too for extra effect.  Children are optional.
 - Apply the patch included in this mail
 - Call your system "Super-67", and don't forget to unapply the patch
   before you later applying the official 1.3.68 patch.
 - reboot
