    I used the guide to setup a mail server with iRedMail.

    Everything appears to work ok except that I can't send mail using a desktop app. Send mail works fine through RoundCube webmail - but I can't authorize via Outlook.

    What should the SMTP settings be out of the box? Maybe I'm just not entering them correctly.

    Any thoughts on what I'm missing?

    Did you enable "Server requires authentication" in your email client?
    Any errors in your mail log?

    I played around for the past couple days and I'm still stuck.

    I was able to get smtp working after an ISPConfig3 Perfect Server - install but only after realizing that my ISP does not allow smtp on port 25 so I did...

    and uncommented
    smtps     inet  n       -       -       -       -       smtpd
    And I was able to send through port 465 using Outlook.

    But I still can't get smtp to work using Outlook with iredmail.

    Here is


    I guess the bold probably plays a role? But where should I go from here?

    Update to this...

    I still can not get this to work using Outlook - but I just tried on my Mac with Mail and could use SMTP except that I had to accept a warning stating that "This root certificate is not trusted"

    Again, I got by without an issue ISPconfig3 without this warning so its got to be something in my configuration. Any thoughts?
