You WANT a brain-damaged sendmail that doesn't look up MX'es??? This is one of the biggest gripes about Suns -- that they don't look up MX'es by default. What you want to do should be perfectly doable with some sendmail.cf tweaking. Please don't lobotomize your sendmail just to get this functionality. Your successor may NOT appreciate your efforts if and when your enterprise network moves to a different mail-routing architecture. MX'es are generally very useful critters. ------------------------------------------------------------------------------ kevin@cfc.com | Kevin Darcy, Unix Systems Administrator ...!heifetz!cfc.com!kevin | Technical Services (CFC) Voice: (313) 759-7140 | Chrysler Corporation Fax: (313) 758-8173 | 25999 Lawrence Ave, Center Line, MI 48015 ------------------------------------------------------------------------------
