Intranet qmail server and totally exposed sendmail server
Hi all, Boss's company asked me to realize this scenario: an internal qmail server to serving co-workers on port 25 (smtp) and 110 (pop3); trhough a FW1 the qmail server must talks on port 24 with a sendmail server that can be sacrified because totally exposed; the sendmail mta server does at this point some relaying for the intranet qmail mta server on the same port (24) with smtp service; I've not problem to configure sendmail on this rules, but I've some problem to do the same with qmail. I tried to add another service like /var/qmail/supervise/qmail-smtpd/run changing the port from smtp to 24. I've no clue how can I do to add another listener smtp on the 24 port. Any suggestion would be very appreciated. Carlo Borelli Project Management Business Unit Tecnologie Data Center Akros Informatica S.r.l.

(Replace sendmail.server.name with the name or IP address of your sendmail server.) that can be sacrified because totally exposed; the sendmail mta server does at this point some relaying for the intranet qmail mta server on the same port (24) with smtp service; I've not problem to configure sendmail on this rules, but I've some problem to do the same with qmail.

That's exactly how you do it. Did it not work? Chris PGP signature
Intranet Qmail server
Hi, Does anybody has already implemented something like this ? A qmail intranet+internet mail server with: - Users (envelopes) with internet and intranet mail relay permitted. - Users (envelopes) with just intranet mail relay permitted. At this time, I\'m running a Qmail server with mail relay for the users, but without any kind of restriction, all users can receive and send mail from inside or outside. The actual relay is based on SMTP-after-POP, with vchkpw. Example of the question: User [EMAIL PROTECTED] can send/receive mail from the internet an from the intranet accounts, but user [EMAIL PROTECTED] can only send/receive mail inside the mydomain domain. And if possible, make foobar get DENIED just to inside-outside relay, and not make messages from outside-inside relay blocked, so anyone can still send mail to intranet-only users. [EMAIL PROTECTED] --- [EMAIL PROTECTED] -- OK [EMAIL PROTECTED] --- [EMAIL PROTECTED]-- OK [EMAIL PROTECTED] --- [EMAIL PROTECTED] -- OK johnsmith pop3 access --- OK [EMAIL PROTECTED]--- [EMAIL PROTECTED] -- DENIED [EMAIL PROTECTED]--- [EMAIL PROTECTED] -- OK [EMAIL PROTECTED] --- [EMAIL PROTECTED]-- DENIED (OK if possible) foobar pop3 access --- OK I\'ve saw this engeneering working on a Novell Netware mail server, with netware users-based relay, made on a simple way.
