I had the same problem with hylafax. I found that its hylafax part of the configuration for logrotate is incorrect.
Modify the path in the file /etc/logrotate.d/hylafax to point to the correct path, which is usually /var/spool/hylafax/etc/xferfaxlog.
As an alternative, a hack would be to symbolic link /var/spool/hylafax to /var/spool/fax.
