Getting authentication error despite correct credentials in tSendmail component?

Ray0801 — Thu, 16 Dec 2021 03:39:05 GMT

Hi All,

I have a mail job scheduled in jenkins has been running properly for about 3 years,

recently we are having this issue where it randomly throws a authentication error on one day, and works fine on some other days with exactly same creds

I also tried with some other mail-ids,we are getting the same

authentication error.

Exception in component tSendMail_2 (xxxx_)

javax.mail.AuthenticationFailedException

at javax.mail.Service.connect(Service.java:306)

at javax.mail.Service.connect(Service.java:156)

at javax.mail.Service.connect(Service.java:105)

at javax.mail.Transport.send0(Transport.java:168)

at javax.mail.Transport.send(Transport.java:98)

at nprinting_to_talend.xxx_email_october_21_0_1.xxx_email_october_21.main(xxxx_email_october_21.java:3457)

Could this have something to do with the System where it is deployed or is it a talend issue.

Any Help will be appreciated.

We are using Talend Open Studio 7.0.1

Hello,

As your job has been running properly for about 3 years, the problem is probably caused by the mail secure. What's your email sever? Gmail or Outlook?

@Xiaodi Shi Our Outlook has double factor authentication,

So I am using the App password Generated in my outlook account as password.

We have tried with multiple mail ids, still the same authentication error persists.

Hello,

Are you able to send email VIA using your authentication (App password Generated in my outlook account as password.) to login your outlook without using Talend tool?

Is the problem in the mail secure?

Best regards

@Xiaodi Shi

Hi Sabrina,

Yes, it works fine when I use the creds to send a mail through a python program.

I dont think mail secure is the issue.

Hello,

Does this issue only repro on V 7.0.1? Have you tried to use other build version(V 7.3.1, V 8.0 ) to see if it works?

Best regards

@Xiaodi Shi I can't install any others versions in the server, but when I tried to run the mail job in my other machine it works fine with V8 &V7.3

Aside,

We also checked the TLS restriction in the Java security file as mentioned in some other solutions of Community, but the TLS versions has not been restricted in our machine.

Could this have anything to do with any firewall block on the machine side and if it would be can suggest some steps we should ask our admin to follow to resolve this issue.

Thank you for you help.

Hello,

As this job works well other machines, the setting and job design should be OK.

What's JDK version are you using on this machine when executing your tsendmail job in studio V 7.0.1? JDK 1.7 or JDK 1.8?

Best regards

Sabrina

Hello,

Please try to perform a telnet test to validate connectivity to your mail server.

Use the telnet command to verify Mail server connectivity and credentials. Perform the test with the same credentials being used on the Job.

From a prompt, type:

telnet Server_address 110

user username@yourdomain.com

pass yoursecretpassword

Type the following command to present a numbered list of emails in the mailbox:

list

Type the following command to display email number 1:

retr 1

Exit the session by entering:

quit

Let us know if you are able to validate connectivity to your mail server.

Best regards

Sabrina
