I would like to disable the feature which checks to see if a post contains header lines which have the address of the mailing list in it (and then flags it as a possible error message). I want to do this because my mailing list is set up so I have no need for this, and it ends up always simply stopping real posts, as it seems that most mailers these days are smart enough to send messages to the correct address. Also, y mailing list only allows subscribers to post, and I have disabled the feature that sends a message to someone who posts who is not a subscriber, so that a mail loop could not be created. I looked at the loopcheck feature, but it's not clear that this type of checking can be disabled using this setting or not, as the only setting that seems to apply states it won't work: Noorigin Allows the list owner to disable the check for "known mailer origins" such as MAILER, POSTMASTER, ROOT, UUCP, et al. Mail whose 'From:' field is the address of the local mailer is still trapped, but wildcard checks on the mail origin are disabled. Any suggestions? Thanks. Mark
