Re: [CentOS] dumb sendmail question -- how to get outbound messages to use "example.com" instead of hostname?

On our servers here are some sendmail.mc lines referring to our domain. May be they will help. These are from our main server:

define(`confDOMAIN_NAME',vigyan.com)dnl CLIENT_OPTIONS(`Family=inet,Addr=vigyan.com')dnl define(`SMART_HOST',`vigyan.com')dnl FEATURE(`smart_host_domain',`vigyan.com ')dnl

These are from our slave servers:

CLIENT_OPTIONS(`Family=inet,Addr=slave.vigyan.com')dnl MASQUERADE_AS(vigyan.com)dnl MASQUERADE_DOMAIN(vigyan.com)dnl FEATURE(`allmasquerade')dnl FEATURE(`masquerade_entire_domain')dnl FEATURE(`masquerade_envelope')dnl define(`SMART_HOST',`slave.vigyan.com')dnl FEATURE(`smart_host_domain',`vigyan.com ')dnl

Good luck.
