I removed sendmail and replaced it with postfix.  There were not any good rpms for postfix and ppc that i could find.  Now when i run apt-get i get the broken dependencies for fetchmail and mutt.

My question is how can i get it to ingnore just these two or fix it(without re-insalling sendmail)as they are not really unmet dependencies.
thanks
matt
