Email puller DISABLED BY SYSTEM FLAG

Hello,

in a sandbox environment I have some issue with the pulling of email in jsm project

 

after some investigation I find the possible cause.

In System> global mail settings  

 

I found this error:

DISABLED BY SYSTEM FLAG

Mail fetching was disabled with the -Datlassian.mail.fetchdisabled=true or -Datlassian.mail.popdisabled=true JVM argument before JIRA was started. JIRA cannot fetch email until you remove the JVM argument and restart JIRA.
What this means? and how can be fix considering we are in a cloud instance?

Hi @Stefano Colagiacomo 

The error you found is a Server DC error only. This can't happen in Cloud.

As these are java arguments states in a startup file, that doesn't exist in Cloud.

So if you get this message in your Jira, you are not on Cloud but on an on-prem installation, contact your IT and who manages the instance needs to shut it down, modify the setenv.sh or setenv.bat file and adjust the JVA arguments.

I'm on cloud and also just saw this error after a sandbox refresh. This appears possible (though rare) even on Cloud.
