Re: [SOGo] External SMTP with user auth

Thank you for the input. Especially

this is important to know. I was doubting that.

Unfortunately, it is still not working. I also tried setting the master user, but I am not sure, whether it works or not. How can I trigger an action, that would use the master user instead of the normal user?

As stated in my first message, SOGo sends an empty "AUTH PLAIN" request to the mail server. Is it possible to see the SOGo part of that interaction? Maybe the mail field or the password field is not properly set due to using LDAP?


Thanks in advance!

Hi,

If your SMTP server is external and requires authentication, then see:

https://www.sogo.nu/files/docs/SOGoInstallationGuide.html#_smtp_server_configuration
SOGoForceExternalLoginWithEmail parameter might be of interest. What is not clear to me from the documentation is whether, apart from using the primary email address of the user, it will also use the user's password to authenticate.
But you can use a master user as the documentation says:

```
If your mail server requires use of SMTP AUTH, you can use the following parameters in the configuration file :
SOGoSMTPMasterUserEnabled = YES;
SOGoSMTPMasterUserUsername = "foo";
SOGoSMTPMasterUserPassword = "bar";

```

    Hi!

    I am not using postfix, but planned to communicate directly with my
    external (hosted) mail server via SMTP. The credentials are the same
    everywhere and seem to be working, since the IMAP is working and I
    can
    see my emails.

    But maybe I am misunderstanding something. No mails can be send in
    general, also no notification with the SMTPMasterUser...

    The SMTP is tested and works with PLAIN auth with the credentials,
    that
    I also use for login.
