I have no 6.X boxes so can't help directly, though I find it hard to=20
believe that postfix+6.X fails for everyone so strongly suspect=20
something local to the way you have installed, though have no clue what.
Some help debugging, though: you sent the output of strace on 6.1 with=20
the wacky file opens. Try the same strace on 5.X and then diff the two=20
to see what ought to have been happening - that may give some clue as to =
what is actually going wrong.
As for USB keyboards + 5.5 - on 5.4 there was an install boot option=20
"boot with USB keyboard" or somesuch. Don't know if that's still there=20
with 5.5, but it sounds like you have a 5.4 CD so you could try that. =20
The problem *may* be that 5.X doesn't support your USB chipset, of=20
course - no idea how likely that is. Also search the BIOS for any USB=20
related options and try fiddling with them! You don't mention the model =
of Dell, but you could try a google for the model + freebsd.
Searching the mailing list archives (or just plain google) for USB=20
keyboard should turn up some stuff as well - possibly far too much!
Final thought - what about postfix-21? Does it do everything you need? =
Does it have the same problem?
