Traccar Mail notifications

I am still not receiving mail notifications.

I done the following:
added mail config

    <entry key='mail.smtp.host'>mail.example.com</entry>
    <entry key='mail.smtp.port'>25</entry>
    <entry key='mail.smtp.ssl.enable'>true</entry>
    <entry key='mail.smtp.from'>traccar@example.com</entry>

I tested ran cmd and did below telnet command:
telnet mail.example.com 25

Got successful connection. I then restarted the Traccar service and still not receiving any mail notifications. Am I missing something??

Below is from wrapper.log file:

Are you really trying to use "mail.example.com" as your mail server? You need a valid mail server. Also, most likely you need to provide authentication to be able to send anything.

Hi Anton, yes I do have a valid mail server. just for the sake of the question i just used fake name. I have tested using telnet and message was sent and recipient received successfully. I didn't put in an entry key for authentication. The admin said I won't need authentication for the mail address I am using. So Now I have just made the entry for username and password blank. Now I don't get that error message in my wrapper.log file but I am still not getting the mail notification either. Anything else I can check??

I tried using my own email address as sender and put in the authentication details and still failed, found below error in tracker-server text file. I even tried to use the sender address which admin provided with blank password and still receive this same error.

2016-08-02 11:58:33  WARN: 535 5.7.0 authentication failed
 - AuthenticationFailedException (... < NotificationMail:124 < *:138 < ...)

Hello, tamati
back to first version of config, is SSL obligatory parameter? did you try without it?

Ok with the first version I removed the ssl parameter restarted the service and i get the below error which is the same as first error I got:

INFO   | jvm 1    | 2016/08/03 09:11:24 | Exception in thread "Thread-27" java.lang.NullPointerException

Please try this build https://cloud.mail.ru/public/9cAC/P9si8AjjF

It is almost clean 3.6 (8d5b4ec5ec) with all last fixes in NotificationMail and applied #2187

SUCCESS!!!!!!!!
I am now getting mail notifications.

Fix:
Replaced the old tracker jar file with the one you provided.
Used mail config below:
<entry key="mail.smtp.host">mail.<example>.net.ck</entry>
<entry key="mail.smtp.port">25</entry>
<entry key="mail.smtp.from">traccar@<example>.com</entry>

Thank you so much for Traccar and your help Abyss and Anton.

Cheers

Dear, what place this setting should be done? It is for interface or configuration file?
Thank you!

Hello, Turbovix
Actually, both. Config will work for all, user attributes will work only for that user.
Second column https://www.traccar.org/configuration-file/ shows the possible places for all parameters.

@Abyss Thanks for the support, it worked, very good!

@tananaev, you need to control spam, since my email box is full of VerkaDori user's message
Thank you

Sorry about that. I'll see what I can do.
