Re: Qmail LDAP on DMZ Smart Host w/ Active Directory

I think this is what you want from qmail-ldap... maybe not though RCPTCHECK Check if the recipient (envelope "rcpt to:") of a message really exists. If not give a 550 reject right now instead of bouncing later in qmail-lspawn. Default: off Affects: qmail-smtpd Example: "" (any value will do) Note: Only applies to recipients whose domain is listed in ~control/locals. Recipients domains listed in ~control/rcpthosts are allowed without further checks. If RELAYCLIENT is set, all other recipients are allowed as well. Addresses or domains listed in ~control/goodmailaddr are unconditionally allowed in all cases.   ----- Original Message ----- From: johnny yu To: qmail-ldap@qmail-ldap.org Sent: Tuesday, December 06, 2005 9:07 PM Subject: Qmail LDAP on DMZ Smart Host w/ Active Directory Hi, I have been using Netqmail 1.05 in my DMZ for a long time.  I use it as a smarthost in my DMZ for all incoming and outgoing email.  My primary reason this is not waiting to expose the Microsoft SMTP service on my Exchange server to the world due to secutiry concerns.  For this purpose Qmail has been great, and I have added a lot of add ons to it like Qmail Scanner and rblsmtpd. However, I would like add the ability to Qmail to have it check to see if a user exists before accepting mail and sending it to Excahgne.  It seemed like Qmail LDAP would do this.  I set up a test system and installed Qmail 1.03 and patched it with the latest Qmail LDAP patch.  I got communication working between my Qmail test system and the directory, but from my testing it seems Qmail LDAP is more ment to deliver mail locally and just use LDAP to store information about the users.  I guess the only functionality I want out of Qmail LDAP is for it to query AD when recieving a message to make sure the recipient in the message is valid.  Is there some way to make Qmail LDAP work in this manner? I have also looked at qmail-activedir, but it doesn't appear to do what I want either. TIA.
