password moderated approval

I've had a moderated list running for some time, although I was not the moderator. It seem that I have forgotten how to approve the messages and the past moderator is gone. I can't seem to find the text in the manual.

I believe the text for approval, with a password is as follows:

approved: moderatorsEmail@service.net_password

I have been trying to approve messages with the above text as well as several permutations, from an Email address which is included in the moderators file, but can't seem to get them out to the list. I've confirmed the password with what is in the rc.custom file. Might someone be able to let me know what I am doing wrong?

Thank you and best regards,

Jack
