-	1. Use `ps -A`  to find the process ID ("pid") for service named `platform` and stop it using `kill [pid]`
-	2. The service should restart automatically. Run `ps -A` to verify the `platform` is running again 
-	3. Use the reset password page (E.g. _example.com/teamname/reset_password_) to test that email is now working by entering your email and clicking **Reset my password**.

 ### Troubleshooting SMTP
 
+#### Tip 1
+If you fill in **SMTP Username** and **SMTP Password** then you must set **Connection Security** to **TLS** or to **STARTTLS**
+
+#### Tip 2
 If you have issues with your SMTP install, from your Mattermost team site go to the main menu and open **System Console -> Logs** to look for error messages related to your setup. You can do a search for the error code to narrow down the issue. Sometimes ISPs require nuanced setups for SMTP and error codes can hint at how to make the proper adjustments. 
 
 For example, if **System Console -> Logs** has an error code reading:

 Search for `554 5.7.1 error` and `Client host rejected: Access denied`.

+#### Tip 3
+* Attempt to telnet to the email service to make sure the server is reachable.
+* You must run the following commands from the same machine or virtual instance where `mattermost/bin/platform` is located.  So if you're running Mattermost from docker you need to `docker exec -ti mattermost-dev /bin/bash`
+* Telnet into email server with `telnet mail.example.com 25`.  If the command works you should see something like
+```
+Trying 24.121.12.143...
+Connected to mail.example.com.
+220 mail.example.com NO UCE ESMTP
+```
+* Then type something like `HELO <your mail server domain>`.  If the command works you should see something like
+```
+250-mail.example.com NO UCE
+250-STARTTLS
+250-PIPELINING
+250 8BITMIME
+```
