FreeBSD - Configure sendmail masquerading

by admin

Notes on masquerading your domain name , I needed that since one SMS gateway will not accept my nagios@server.domain.com emails , this setting allowed nagios to send the email as nagios@domain.com

  • tar zcf etc_mail_backup.tgz /etc/mail !!!

  • cd /etc/mail

  • sudo make cf

  • sudo vi hostname.mc

  • add:MASQUERADE_AS(domain.com)dnl
    FEATURE(masquerade_envelope)dnl
    FEATURE(masquerade_entire_domain)dnl
    MASQUERADE_DOMAIN(domain.com)dnl

  • make sure this is added BEFORE any “mailer” definitions

  • sudo make

  • sudo make installf

  • sudo make restart

worked on FreeBSD 6.2
