SunOS 4.0.3 patches

[D. Whiteley]

Recently I installed SunOS 4.0.3 on several Suns.  I've noticed problems
here and there that might be known bugs.  So I was wondering if anyone has
a list of all known patch tapes available for 4.0.3. 

Also, does anyone know where I can get sendmail 5.61 for Sun 3's and 4's?
A recent CERT advisory said this is the most secure sendmail.  The
sendmail at uunet.uu.net is sendmail 5.59.

Thanks,
Denice
