Mail not reaching a specific user

Question

Hello,
We have a user who is not receiving Jira mails. How can we resolve this situation?
User,
-org&site admin.
-all personal settings are turned on.
-There is no restriction on the e-mail on the organization side.
-Everything looks ok when checked with Notification helper.
-Confluence emails are coming.

While everything seems ok, no solution was found, where should we look?

Hi @Lucas Modzelewski _Lumo_ ,

-Yes, it affects all jira notifications. Mentions, all events etc.
-It's a user email, there is no problem with other user emails in the same domain.

I will also contact Atlassian support, thank you.

Hi @Seran Poyraz ,

Welcome to Atlassian Community!

Does it affect all Jira notifications? From projects for all events and filter subscriptions? Even @ mentions in comments?

Is it user email, not a generic maile used in some email handler?

The fastest option would be to contact Atlassian support directly: https://support.atlassian.com/
