[Sheflug] Wonky ip-up (second try)

Hello again. Now I have sorted getting fetchmail and sendmail to what I want I
would like to use them in my ip-up, not unreasonable. Yet nothing appears to
happen, I use the default ip-up from Suse6.3, and I do know that it is being
executed because /var/log/messages says it is. t is attatched for convenience.
If anyone could offer explanation I would be grateful.
