Dynamics 365 business central – how to setup email (smtp

One of the first steps in troubleshooting mail flow problems with any mail server is to try telneting into the server’s port 25. The smtp link was not authenticated, according to Exchange error 530. It’s a good thing you’re trying to relay through an Exchange server because you don’t want an open relay. If you’re trying to relay to an Exchange server, though, this isn’t a good idea. So, let’s have a look at how this symptom appears. Second, we try telneting into the server’s port 25:
We can now look at the receive connector for Exchange, which is part of Hub Transport. To do so, go to the Server Configuration section of Exchange System Manager or Exchange Management Console and pick Hub Transport.
Check the box for Anonymous users in the Properties dialog. Since that other server is essentially just running through the message dialog we worked through earlier when telneted into the host, another mail server will communicate with yours over smtp. To save the changes, click Apply, then stop (disable) and start (enable) the connector for a laugh. Spread the word:

Smtp server requires a secure connection or the client was

The default authentication settings of the Exchange (2007 and 2010) SMTP receive connector are to blame for the problem. The receive connector only enables authenticated transfers by default. POPcon, on the other hand, cannot authenticate itself to Exchange because it simulates incoming email from remote servers.
With the Exchange Management Console, you can change the authentication settings: Navigate to Server Configuration -> Hub Transport in the Exchange Management Console to locate receive connectors. The Receive Connectors tab will appear after you’ve selected your server. The “Default” receive connector on Hub is set up to authenticate with other Exchange servers, but it does not allow anonymous email by default because it needs to accept SMTP emails from outside/POPcon.
On the same server, the “Default” receive connector is usually the one that is active for SMTP connections (that is where POPcon sends from). If you’re using Windows Small Business Server (SBS), there may be a “Fax sharepoint” receive connector that’s also the active connector for SMTP from POPcon; if that’s the case, change it as well.

Smtp server error: 5.7.1 : recipient address rejected: access

I’m having an odd problem with Exchange 2010 version 14.03.0158.001. (latest to date). The receive connector is set up correctly, with anonymous users tested, but I can still receive mail in plaintext and TLS from some servers (like gmail and some hosts I have access to), but not from others, which are perfectly legitimate and support TLS and plaintext as well.
Check each receive connector’s IP address ranges on the network tab (Exchange management console > server setup > hub transport > receive connectors): A receive connector that isn’t configured to allow anonymous access may be serving the failing host / IP address (“[1.2.3.4]” in your example).

The server response was 5.5.1 authentication required gmail

If the client is not authenticated, the SMTP server needs a secure connection. 5.7.1 Client was not authenticated, according to the server response. System.Net.Mail.SmtpExceptionPrintable is an exception form.

Reproducible Measures
Providing Clarification
– Search the attached file EmailSender.zip to see if the SMTP server is either unreachable or experiences an error when a link attempt is made from the site’s server.
– Open it in Visual Studio and change the code in Program.cs to send an email to the SMTP server of your choosing. – If this code successfully sends an email to the SMTP server, make sure to run it from the server where the site is hosted and the issue occurs. – It’s possible that the issue is only replicated when email is sent from the Sitefinity server. The issue is unique to the context in which the site operates, not to the Sitefinity site, since the SMTP server is unreachable only from one environment (the server where Sitefinity is hosted).
