having e-smith act as a secondary mx

[Brian Moore]

gretings all.

have added a line to my /etc/smtpd_check_rules file like the folowing to
allow my box to act as a secondary mx server for another domain  wonder if
this rule is correct.  looks like it would be right to me but want to make
sure.

allow:all:all:*.domain.yi.org *@domain.yi.org


if this is incorrect, what am I doing wrong.

thanks for any tips.

brian.
