I don't think you need the above "define" if your .mc file already has FEATURE (use_ct_file)dnl

The use_ct_file feature will add the proper tags in your .cf file for the use of the trusted users file.

> In /etc/mail/sendmail.cf I see:
> #####################

> #####################

If you add the use_ct_file feature as shown above, then the reulting sendmail.cf file will contain…

#####################
#   Trusted users   #
#####################

# this is equivalent to setting class "t"
Ft/etc/mail/trusted-users
Troot
Tdaemon
Tuucp

Note the difference in the trusted users line.

BTW: It's the -o thats incorrect. should be

define(`confCT_FILE', `/etc/mail/trusted-users')
