Emails to external accounts fails in Npriniting June 2018

[Anonymous]

Hello everyone,

Looking for guidance from the NPrinting users .

We recently upgraded to June 2018 and have been facing this weird issue of emails not being able to sent to an external account like( Gmail,yahoo etc). I keep getting a message unable to relay error when i send to external environment.

Also could anyone let me know what Username/PWD should be given in the email settings of NPrinting. I gave my service account which has a mailbox as the username but then it didn't allow any custom user to send emails.

From the log, I get the below error messages when I try to send emails to external domain,

Failed to send e-mail message to abc@gmail.com.

ERROR: MailKit.Security.AuthenticationException: AuthenticationInvalidCredentials: 5.7.3 Authentication unsuccessful↓↓  

at MailKit.Net.Smtp.SmtpClient.Authenticate(Encoding encoding, ICredentials credentials, CancellationToken cancellationToken)↓↓

at MailKit.MailService.Authenticate(String userName, String password, CancellationToken cancellationToken)↓↓

at Qlik.NPrinting.Repo.Service.MailService.<SendEmailAsync>d__6.MoveNext() in c:\Jws\release-v18.19.x\server\NPrinting\src\Repo\Service\MailService.cs:line 93

Thanks in advance and really appreciate all the help.

Hi,

The log says "Authentication unsuccessful" and the Username and Password are empty. You must enter there the credentials of the user you created in your SMTP server. After the SMTP server will accept connections from that user and will start to send email.

Please check also the anti-spam configuration of the SMTP server with its administrator otherwise you risk that Qlik NPrinting starts to send email but stopped after a bit due to the SMTP anti-spam rules.

Best Regards,

Ruggero

Hi Ruggero,

Thanks for the response.

However I have few questions here.

As mentioned , In the email settings -"You must enter there the credentials of the user you created in your SMTP server."

- Is there a separate email ID that needs to be created. I basically requested my service accounts to have a mailbox attached to it and I intend to use the same in the email settings,

When I enter the Username/PWD in email setting of Nprinting, I see that my custom user option doesn't work and it throws the below error.

Failed to send e-mail for bucket 5fc384cf-f564-47b1-891c-22be00fda1b2 to abc.com. ERROR: 5.7.1 Client does not have permissions to send as this sender.

And in this case, I am not even able to send emails to internal accounts as well.

Any insights would be helpful

this is not a NPrinitng issue. Talk to SMTP server admin in your company. He/She needs to provide you with all required fields and possibly allow your account to sent emails as service. Also notice that if you will setup your account as a nprinting sending email it will possibly land on the spam list since it will be producing in very short period a lot of mail. Nowadays system are recognizing this behaviour so your email should also  be whitelisted in SMTP.

Again - this is purely SMTP server problem and is narrowed down to settings used in your company.

cheers
