freebsd> Is it necessary to tell sendmail inside a jail to listen only on that freebsd> jail's IP? If so, how is this done?

No, but you need to make sure that the "host" system's sendmail isn't listening on the jail's IP addresses using DAEMON_OPTIONS(). I run a jail system which houses 1 "host" system and three jails. Each of the jail's .mc files are pretty much the same as /etc/mail/freebsd.mc. The "host" system (zim.gshapiro.net is it's hostname) .mc file is: OSTYPE(`freebsd4')dnl define(`confDONT_PROBE_INTERFACES', `True')dnl DAEMON_OPTIONS(`Name=gshapiro.net, Addr=zim.gshapiro.net, Family=inet')dnl DAEMON_OPTIONS(`Name=localhost, Addr=localhost, Family=inet')dnl FEATURE(`no_default_msa')dnl MAILER(`local')dnl MAILER(`smtp')dnl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
