Problems with sending notifications in JIRA

[Alejandro Rodriguez]

Hello everyone. 

Two days ago the server where my Jira software is hosted got full and I could'nt do anything so I had to expand the space in the server. But after I did that the notifications aren't getting to the people. I mean the notifications is not working in JIRA.

This is the error that shows up : 

An error has occurred with sending the test email:
com.atlassian.mail.MailException: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.mandrillapp.com, 587; timeout 10000;

Hi @Alejandro Rodriguez ,

Welcome to the Community!

Given that the error message says unknown host exception, it sounds like the Jira server is unable to locate the machine your SMTP server is running on.

You might want to try the steps listed here: https://confluence.atlassian.com/jirakb/unable-to-send-mail-due-to-could-not-connect-to-smtp-host-297665338.html

I would try running those from a command prompt/terminal on the Jira server machine itself to verify that you can actually connect to the SMTP server from the Jira server outside of the application.  If you still can't connect you will probably want to involve your companies network engineers to assist with the connection issues.

I hope that helps!
