SAP Cloud Platform Integration (CPI) || Part 6 || Configuring Mail Adapter

Dear Reader,

This blog post is a part of a series of blog posts related to SAP Cloud Platform Integration. The blogs so far are:

  • My adventure in learning CPI || Part 1 || All about SAP Cloud
  • My adventure in learning CPI || Part 2 || Deployment Models
  • My adventure in learning CPI || Part 3 || Cloud Security
  • SAP Cloud Platform Integration (CPI) || Part 4 || Know your tool
  • SAP Cloud Platform Integration (CPI) || Part 5 || Content Modifier

Up next:

  • SAP Cloud Platform Integration (CPI) || Part 7 || Maintaining logs/ using “Groovy Scripts”, even if the IFlow is not on trace mode.

———————————————————————————————————————–

Various adapters (i.e. technical protocols which are used to connect a sender or receiver to the tenant (CPI), are provided by SAP, such as SOAP, OData, Mail, SuccessFactors, HTTPs, Ariba, Facebook, Twitter, ProcessDirect, etc).

In this blog, I shall explain to you about the Mail adapter.

 

The below is the IFlow, where I have used (a) a Start Timer which means, the message will trigger, the moment the IFlow is deployed, (b) a Content Modifier, just to show how to call the elements in the body of the email.

You can call the Header as, ${header.elementName}, Property as, ${property.elementName}, and Message Body as ${in.body} in the subject/ body of the email.

In my example, I am trying send an email from a Gmail ID.

For the Connection setting refer the screenshot below that needs to be maintained. 

1. Address, the address maintained is smtp.gmail.com:587 where, smtp.gmail.com is the address which allows the sender to an email and check the domain of the sender through the email ID provided, and 587 is the port behind the SSL certificate for security. Now, this smtp.gmail.com is applicable only for Google Customers i.e. gmail users.

There are different standard ports used by Google, Microsoft, Yahoo, Rediff, or Godaddy such as 587, 465, 995, 993, and 25.

2. Credential Name, is to be maintained in the Security Material.

In the Operations View, go to Security Material, and add User Credentials.

Enter your ID, and password of your Gmail account, and Deploy.

Please ensure that your ID is unblocked for API mail sending.

3. Under Mail Attribute, mention the your ID which has been unblocked for API mail sending, and the receipient’s email addresses followed by a (,).

In the Subject, and body, mention enter your email context, and as I have stated earlier, you can call the Header, Property, and Message Body of the content modifier.

 

After you deploy, a message shall be triggered, and you shall get an email like the below:

Click on “Check Activity”, and click on, “Yes, it was me”.

Now, go to Manage Account:

Here, “Turn on” the Less secure app access.

 

After you are done, making these changes, re-deploy the IFlow, and you shall get an email like the below:

 

 

That is it about the mail adapter.
Hope you had a good read.
If you wish to know more, or have any queries on the said processes, then please feel free to drop a comment.
 
Thanks & Regards,

  • Hi Sookriti,

    using gmail server in Mail receiver adapter always work.

    Did you try smtp.office365.com.?I am getting below error

    Message processing failed.
    Processing Time: 15 sec 887 ms
    Error Details
    javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful [SY2PR01CA0005.ausprd01.prod.outlook.com]
    Do you know how to send email office365?
    Thanks
    Harsha
    • I have never tried with office365. I am sure there must be other blogs on this mail server’s connectivity.

      From the error, it seems more like the email ID which you have used has missing authorizations. As I have mentioned make sure the email id has been unblocked for API mail sending.

  • Hi Sookriti,

     

    Please confirm me whether we need to do two step authentication from Gmail and need to provide that in credentials.

     

    • Not required. The essentials steps have been mentioned in the blog. The “app access” is required.

      The first time, you will trigger the email, you shall get an email stating about “Security Alert”, from there on, you just have to allow access.

  • Hi Sookriti,

    i setup the mail adapter as you recommended in the blog.

    Unfortunately I receive the following error in the message processing monitor

     

    Do you know why this error occurs?

    thanks and regards,

    Julian

    • Julian,

      From the Manage Keystore under Monitor view, add a Certificate for Gmail and re-deploy your iFlow. This should probably resolve the certificate issue.

      Thanks,

      Arun

          • Hi Arun,

             

            Which certificate should I download for email, I tried with a few of them on mentioned website, but I still receive the same error.

             

            Thanks,

          • Hello Priyank,

            This is just one way of doing it. If this doesn’t work, you may try the other way. See below.
            Go to the Connectivity Tests tile and use the SMTP test using your email address. From the resulting response, you may simply download the certificates and have them installed. This is actually the easiest way.

            Hope this helps.

            Thanks,
            Arun

    • Hi Julian,

       

      Is this resolved?

      If yes, please let us know the way in detail so that it would be useful for the members who may face same issue.

      Thanks in Advance.

  • Thanks Sookriti. Appreciate your time taken to help others with your blog.

    For Gmail, in addition to the settings for less secure apps, I also had to enable the option to bypass the Captcha verification. Only then, I received an email.

    Looking forward to more such articles.

    Thanks,

    Arun

    Below steps need to be followed to send email from SAP CPI via mail adapter,

    1. As mentioned above, install the gmail certificate from https://pki.goog/. I installed the gmail certificate name, GS Root R2 and RSA 2048 from this link.

    2. Make sure Less secure apps is TURNED ON in your gmail account

    https://myaccount.google.com/lesssecureapps?pli=1

    3.  To allow each app to send email, enable the access using the below link
