The issue is now fixed in incremental update v 1.160.135 released yesterday.
Issue observed in v1.160.**
Fixed in v1.160.135
Hi Folks,
We are facing SMTP server email sending failed issue post updating our managed deployment to v1.160 previously it was working fine. No changes were made in the settings since last 3 months, I am clueless how to troubleshoot the issue.
Note:
1) Port is opened from the cluster node (checked)
2) We are able to send a test email directly using the telnet client from the server itself
Any help to troubleshoot this will be appreciated
Solved! Go to Solution.

Anything valuable in the server debug log?
Look for lines with MailSenderImpl in the debug log. There will be the reason of the failure.

Hi Július,
As instructed I have analyzed all the debug logs available in the cluster node but no entry found with MailSenderImpl.
Logs analyzed
Server_Debug.0.0, nodekeeper_Debug.0.0, Server_Debug.0.1, audit.debugui.0.0, Server_Debug.0.2

Try again the test. It works in my environment. As long as I (badly) configured the SMTP port/address/... the line with MailSenderImpl (and with the reason) appeared in the Server_Debug.0.0 logfile.

Found the following error in the Server_Debug0.0 log file

It looks like your sender email has been disabled on Mail Server somehow.

But I am able to send/receive emails using Outlook client and WebMail Portal
04 Feb 2019 11:19 AM
On outlook client you are not using any encryption as well?
04 Feb 2019 11:55 AM
Right, I am not using any encryption on Outlook client. meanwhile, we are checking with SMTP team for the exception we are getting in the logs.

If all credentials are correct, this means thet adding setFrom parameters on JavaMailSender doesn't work somehow... This is Sender email address field in form. What you can try is to put there different email, make test, and put right one again. Stupid but maybe this will store proper value... If not open support ticket.

I have already done this with 5 different working email accounts none of the accounts is working. I can confirm that all the provided credentials are correct.

I'd recommend to check the authentication from command line. Some example here (exact login mechanism depends on your SMTP gateway)

I am raising a support ticket as I have confirmed that no changes have been made at the SMTP server and the Email support team tested using command line by sending email from telnet, they are saying that there is some problem with Dynatrcae as they are able to send emails from every possible channel (Outlook, portal etc) available without any extra effort

Update this question when you will have resolution 🙂 It may be helpful in the future.

Hi All,
The support team has acknowledged the issue and they are aware of the email sending issue after the 1.160 update. They are currently building a fix to address the issue. They will release the fix update as soon as it becomes available.
The issue is now resolved in incremental update v 1.160.135 released yesterday.
