[fetchmail]Pb on HP-UX but you could be interested

Hi

Since I tried to install fetchmail on an HP-UX 10.20(with binaries), I
have some network problems:
    - Some network  services doesn't work.
So, I have uninstalled fetchmail,but the problem is always here. For
example, sendmail doesn't send any mail, even if we reboot the system.

We think that this doesn't come from sendmail.
Is it possible that fetchmail could be the guilty of my problems ?




thks


PS: Could somùeone tell me which system files are modified when we
install fetcmail ?
