Temperature@lert: Troubleshooting Emails Not Sending

When in developer mode if you click the send "Test Mail Server" button and an email does not appear in your inbox, this could be due to a few common issues. This guide will cover the most common occurrences.

Spam Folder
Emails from Temperature@lert often end up in SPAM folders initially. Please check your SPAM folder to see if the test message mistakenly ended up there. To prevent this from happening again, please add the from address to your safe senders list (this step varies in each email problem). Please check with your email vendor for instructions on how to add the from address to your safe senders list.

SSL/TLS
If your server requires SSL or TLS authentication, simply click the "Enable  SSL/TLS" radio button. Please note that this will likely require you to change the "Port" as well.
 
If you are unsure, check the error.log file in your Temperature@lert folder (typically c:\program files\temperature@lert on 32-bit systems and c:\program files (x86)\temperature@lert on 64-bit systems). If the error log contains this message: "SMTP protocol error. 504 5.7.4  Unrecognized authentication type", your server requires SSL or TLS Authentication.

Firewall Issues
Many networks have firewalls or other security measures to intercept emails from unknown senders. Please ensure both the Temperature@lert emails are allowed through any network security features, otherwise, emails will not be sent.
 
Check the error.log file in your Temperature@lert folder (typically c:\program files\temperature@lert on 32-bit systems and c:\program files (x86)\temperature@lert on 64-bit systems). If the error log contains this message: "Connection timed out" or "Host could not be reached", you may have a hardware or software firewall (such as Norton or McAfee) blocking the connection. Please try opening a port on your hardware firewall (default is 25, SSL/TLS port 465/587) or unblocking the Temperature@lert program in your security software.

Gmail Email Not Sending
If you are using the Gmail SMTP server along with a Gmail account, you will have to enable less secure apps. This will allow our Temperature@lert software to send mail via Gmail. Please click here to log in to your Gmail account and enable less secure apps.

Using Out-of-Date Software
If you see the following error: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExeptionDetailInFaults (either from SerivicesBehaviorAttribute or from the <seriviceDebug> configuration behavior) on the server in order to send.

Make sure to use the latest version of your operating system.
