That is the option I recommend. Look at the mailman port. Mailman is a very nice (though not perfect) mailing list management system. I see that there is also a port for majordomo if that is what you prefer. But I find that mailman is easier for my users to cope with. What is the best way to have a list that only certain users are able to send to? I am open to suggestions that will get me out of this situation. You have already given the answer. Use a mailing list management system like majordomo. I recommend mailman. By the way, mailman is what is used for managing the FreeBSD mailing lists. The announce list is set up so that only certain individuals can post to it. -j -- Jeffrey Goldberghttp://www.goldmark.org/jeff/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have disabled the alias, since I didn't know if there was a way to restrict who can send to aliases, but is there a good way to have a list of users that either a) doesn't give the list name in the email, or B) a list program like majordomo or something that I can keep people from using who isn't 'the boss'? What is the best way to have a list that only certain users are able to send to? I am open to suggestions that will get me out of this situation. I don't have your setup, but I could guess what I would do with mine: I wouldn't try to stop folks from sending to that address, instead, I would block it on the reception side, so only a given set can get thru to be re-echoed to. Blocking on the receive side, that's something that is very well covered in a huge number of tools, blocking on the sending, that's one heck of a lot more difficult. Wouldn't it give you the same effect, or does the filtering occur at the wrong point in your processing, to be able to block the retransmission (time to test it).

Someone recently sent out an email to the all-staff that someone didn't like, so now I have to restrict who can send to it. If one is willing to consider replacing sendmail with postfix it appears there may be several ways to restrict who may send messages to an address. man 5 access and man 5 header_checks are my first guesses. Header_checks seems to run before the message is queued. If there is a match you can accept, reject, redirect, or many other things. OTOH if only a few people are allowed to send to all-staff then maybe it would be best to manually maintain a mail list in their personal address books? Another way to deal with it would be to rewrite the all-staff header with a bogus undeliverable address so that the minions don't know what the single whole world address is? So that if they reply it doesn't deliver, or it only delivers to a few select people? Only the privileged few know the real-all-staff email address. I know, its security by obscurity but when absolute security is not needed and all that is needed is protection from the ignorant its often plenty good enough. -- David Kelly N4HHE, [EMAIL PROTECTED] Whom computers would destroy, they must first drive mad. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I set up the minimalist port for a small list last year. Small very easy to config. I think it has the restriction you want. -R ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You can use Majordomo, and set the parameter `restrict_post' in `listname.config': restrict_post = listname.allowed where `listname.allowed' is a file containing addresses from which messages to the list will be accepted. In addition, you may want to configure `/etc/mail/virtualusertable' as in Majordomo FAQ 3.6, http://www.greatcircle.com/majordomo/majordomo-faq.html#3.6 HTH, Raghavendra. -- N.
