Hi, Have cyrus on my linux box, users are all working fine as long as they have the "my server requires authentication" selected in their cleints. However, one of my clients have Aureate ( a list mailer util for windows) installed, and it keeps giving "relaying denied" messages when they try to send to addresses off my server. Aureate has an "authentication" section, yet it returns an error in it's log: SMTP authentication not supported. It looks like it is my server that is generating this message, so;
1) How do I ( should I ) enable smtp authentication.
2) How can I get Aureate to stop moaning without making server changes.

If the error is in the application's (Aureate) log, then I'd take that to mean that the application doesn't support using SMTP authentication. You'd get different errors in the server's logs if the client application attempted to authenticate and failed.

If you have a case where a particular client isn't able to use SMTP authentication then the only recourse is to try to use an access map entry to allow the client application to relay mail through your server. That would require entering the IP, or hostname, or domain name of the client in the access map, something line one of the following:

1.2.3.4                    RELAY
clueless.win-app.tld       RELAY
win-app.tld                RELAY

Obviously the first two cases above require that the client system have a static IP, which wouldn't be the case for an ordinary dial-up to most ISP's. The last case does pose a risk or your SMTP server being abused if there are any spammers at the domain specified. It's probably reasonably safe to use the domain name if the client is part of some trustworthy organization. But it probably wouldn't be a safe thing to do if the domain belonged to an ISP.

Solution was an upgrade to a later version of Aureate, even though they persist that that version DOES support it...
Strange that users seems to know more about their own software...
