SENT MAIL OPERATOR

Alexandros_Tzekas51

Let's say i have a dataset that contains temperatures, pressures, etc and I want to use the operator "Sent Mail" so that below a minimum value and above a maximum value of temperature it would send me a message to alert me. Could anyone tell me how exactly I should use this particular operator in this example (parameters, other operators etc)?

Hi @Alexandros_Tzekas51,

you need to set the SMTP email settings for the account you want to send from in RapidMiner.
In Studio this is done in your preferences/Tools/SMTP. In Server this is done in the standalone.xml.
(see https://docs.rapidminer.com/latest/server/administration/server-settings.html#change-outmail).
However, gmail is restrictive when it comes to security - you probably need to change some settings in your gmail account.
More info can be found here: https://community.rapidminer.com/discussion/53861/re-smtp-server-problem-and-security-issue

Happy Mining,

hi @Alexandros_Tzekas51 I'm sorry but I'm out of ideas. Setting up email can be tricky.

Happy holidays.

hi @Alexandros_Tzekas51 so just build whatever process you want so that the result is the ExampleSet you wish to email to yourself. Then use the very handy "ExampleSet to HTML" operator in the Converter extension to convert to HTML. Then you can use Send Mail. Something like this:

<?xml version="1.0" encoding="UTF-8"?><process version="9.1.000">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="9.1.000" expanded="true" name="Process">
    <parameter key="logverbosity" value="init"/>
    <parameter key="random_seed" value="2001"/>
    <parameter key="send_mail" value="never"/>
    <parameter key="notification_email" value=""/>
    <parameter key="process_duration_for_mail" value="30"/>
    <parameter key="encoding" value="SYSTEM"/>
    <process expanded="true">
      <operator activated="true" class="generate_data" compatibility="9.1.000" expanded="true" height="68" name="Generate Data" width="90" x="45" y="85">
        <parameter key="target_function" value="random"/>
        <parameter key="number_examples" value="100"/>
        <parameter key="number_of_attributes" value="5"/>

        <parameter key="gaussian_standard_deviation" value="10.0"/>
        <parameter key="largest_radius" value="10.0"/>
        <parameter key="use_local_random_seed" value="false"/>
        <parameter key="local_random_seed" value="1992"/>
        <parameter key="datamanagement" value="double_array"/>
        <parameter key="data_management" value="auto"/>
      </operator>
      <operator activated="true" class="converters:example_set_2_html" compatibility="0.4.001" expanded="true" height="82" name="ExampleSet to HTML" width="90" x="179" y="85">

        <parameter key="body_html" value="&lt;html&gt;&#10;&#9;&lt;head&gt;&#10;&#9;&#9;&lt;title&gt;RapidMiner Mail Message&lt;/title&gt;&#10;&#9;&lt;/head&gt;&#10;&#9;&lt;body&gt;&#10;&#9;&#9;&lt;p&gt;%{htmlMacro}&#10;&#9;&#9;&lt;/p&gt;&#10;&#9;&lt;/body&gt;&#10;&lt;/html&gt;&#10;"/>
        <list key="headers"/>

      </operator>

Good Morning my Brothers!

I have a Big Problem here! I have a gmail so my SMTP Settings should be configured like this:

• server address: smtp.gmail.com
• adress: alexandrostzekas@gmail.com
• pass: MyPassword
• port: 465 (i checked it)

But it didn't work! So i created 3 other emails: yahoo, mail and hotmail. I figured out that the only thing that changes is the server address which is smtp.mail.yahoo.com for yahoo, smtp.mail.com for mail and smtp.live.com for hotmail.

I used them all but it was a failure...!

You have any idea what is going wrong?

Hi @Alexandros_Tzekas51,

Did you set the Authentication type? Maybe StartTLS is necessary.

At least for gmail I know that you need to enable not trusted Apps (see https://support.google.com/accounts/answer/6010255?hl=en) in your account settings.

Let me know how this works

Happy Mining,

Edin
