Have the sendmail developers been informed about this?  Seems that
sendmail uses /etc/service.switch to do the same thing unless the OS
already has a mechanism, but only Solaris 2, Ultrix and OSF/1 are
implimented through the OS in sendmail 8.7.5.

Or is all of this going to be superseded by nsswitch?

Or what?
