Hi I am aware of those two documents and do plan to proceed with my installation based on them. <div>On 9/20/05, John Dennis <<a href="mailto:jdennis@redhat.com">jdennis@redhat.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Tue, 2005-09-20 at 21:12 +0530, Nabeel Moidu wrote: > Hi > I am ready to use any of the mailing lists available for postfix. > But i think mailman or ezmlm would be the preferable postfix does not have mailing lists, it has aliases. If you want a full featured mailing list (e.g. mailman) that is an entirely different piece of software (which may elect to utilize postfix as its MTA if it so desires).</blockquote><div> I do use a full featured mailing list presently but its a qmail/vpopmail/courier-imap/ezmlm on Solaris setup which i would like to migrate to a postfix/cyrus/mailman on RHEL4 setup. </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I am the maintainer for the mailman package here at Red Hat and I'm just finishing an LDAP module for mailman. But you need to realize mailman uses its own set of users based off of its own set of mailing lists, there isn't an automatic mapping of system users to mailing list members, which is what you seem to be expecting. -- John Dennis <<a href="mailto:jdennis@redhat.com">jdennis@redhat.com</a>> </blockquote></div>I would be satisfied if the mailing lists can be maintained seperately using its own list while the users are stored in the directory server, but the only issue is when the mail server receives a mail, an ldap lookup by the Spam Firewall (We use Barracuda here) shouldn't result in it rejecting it as an invalid user since the lists are maintained seperately. Can this situation be overcome anyhow? And as for the LDAP module you will be releasing , Will it be for storing the lists completely in the ldap server?Can the list entries map to the existing user account in the LDAP server?
