If it is sendmail and if you had manually edited sendmail.cf, there is some good chance that the customization was wiped clean by the latest sendmail update. I saw this behavior -- there was no .rpmnew or org file created by sendmail. Of course, one is not supposed to manually edit the .cf file. Still, this is not the way sendmail used to update the conf file. Akemi
