Outsystems 5.1 / SSL / SMTP Problem

Good afternoon,

Our client has an Outsystems 5.1 infrastructure, and recently acquired and installed a Certificate on the Production Server, to allow secure outside access to their Outsystems Applications.

One of the features developed was the ability for sending automatic notifications by email, using one of the Client's SMTP Servers. Problem is, after the certificate was installed, the sending of those email messages stopped working, returning the following error:

Error creating Email. The remote server returned an error: (403) Forbidden.

Is there any aditional configuration setting we have to make on the Outsystems Platform, or on the Clients SMTP Server (i.e. change the protocol from SMTP to Secure SMTP)?

Fact: One of the Client's system administrators was able to relay an email message manualy, by establishing a telnet session on port 25 to the SMTP server.....

Client is running Outsystems 5.1.1.16 on Windows Server 2003, with a remote SQL Server instance.

Has anyone already came accross with such a scenario?

Thank you all in advance.

Hi Paulo,

Good morning Ricardo,

As requested, here is the error log:


Thank you very much in advance.

Hi, 

that seems to be a http error and not a smtp problem.

Did you published the solution after you installed the certificate?

Ricardo,

The solution was fully published after the installation of the Certificate.

Hi Paulo,

Did you turn off http connections completly to force the https? It's required to allow http in local connections (127.0.0.1:80).
If that is not your problem, try checking your IIS logs to see what request is actually returning the 403.
