I've configured such a system myself, it's no biggie really, since you already have set up sasl & stuff. You don't have to set up any "duplicate" -systems, just configure your postfix to allow relaying if user is authenticated, that's basically it. My postfix is also set up to listen SMTP/SSL TCP-port (465), since my ISP is blocking port-25 connections to anywhere else than their own mailserver (found that out after hours of debugging). TLS works on port 25, so it's possible to use that also, port 465 is strictly SSL. Blocking port-25 access seems to be quite common nowadays (due to viruses & spam), so I've told everyone just use port 465 and SSL (oh, and that's the only secure-smtp apple mail understands). I can post critical parts of postfix configs later on, now i'm in a bit of a horry. Net is also full of tutorials for this, just google for "postfix sasl authentication", it's not that uncommon setup.

I have closed my postfix down so we're not open relay, I've tested this thoroughly. As well as serving the current users, (IMAP or Pop3), where they send out their messages through their own ISP's SMTP servers.. I want to be able to allow any of my users to configure their email client, outlook, whatever, to send directly through my SMTP server, using their own password, hopefully using TLS

makes sense?

hi Carlos..

Debugging Sasl is a pain ;-)

I don't really get what you want to do, if you have your Setup running i assume your clients can get
and send mail from/to your server. (Hope you aren't a open relay)

So whatfor do you need a seperate instance? What do you want to achive?

Hi all:
I have had WebCyradm working for a few months now, excellent work from dev
I am stuck though in one little spot:
I need to make SASL authentication work, so any valid SMTP client can forward through my server. Would you recommend setting up a second instance of postfix- cyradm to do that, in the same box, different TCP port? Would you be able to give me some help / hints if I paste here my config files?I tried the telnet localhost 25 test, and I am not sure I'm pasting the right password for one of my valid email accounts, because it says it

got user name not the password..I'm lost here.Thanks,
Carlos H.
