hi @eugene
Can you tell me, how could you implment email sending service? i have used this example https://github.com/camunda/camunda-bpm-mail but i couldn’t send mail to my gmail account

Hi Sally

It can be that Google blocks the requests because it estimates your application as unsafe, and your.name@gmail.com may even received an email from Google to inform you about this.

To fix this, log on as your.name@gmail.com, then go to Anmelden – Google Konten and enable less secure apps.

Hi @eugene,

do you see any errors in the log file?

Best regards,
Philipp

hi @Philipp_Ossler

Thanks for responding.

Nope, none at all. All seems to work fine and the email is received but no attachment is present. I suspect it might have something to do with the latest versions of javax.mail, camunda-connect-core and slf4j-api. I’m not a programmer and find it difficult to investigate in depth.

I notice that the same happens when I send an HTML email. It succeeds with no errors but the received email has no body.

Thanks for your attention to this issue.

Hi @eugene,

it can be that it’s related to the libs you use. Can you tell me more about your setup?
Did you copy the JAR files in the tomcat lib folder?
What JAR files are in the folder?

Best regards,
Philipp

2 I did not copy them, but added the dependencies in the pom as can be seen in my first post

Thanks for your assistance. If there’s anything else I can do to help, please shout.

Hi @eugene,

I tried but I can’t reproduce the issue. I set the version of javax.mail to 1.6.1 and send the mail via Gmail. It works as expected.

What mail provider do you use?
Did you have any new information that can help to reproduce the issue?

Best regards,
Philipp

@Philipp_Ossler

Eventually I uncovered the problem. I physically copied the 3 dependencies to the …/lib/ directory AND added the dependency definitions in the .pom. If I comment out the dependency definitions it works fine. Maybe it makes perfect sense to a Java developer … :star_struck:
