Mail room for Cells
Check gitlab-org/gitlab#442161 instead
Overview
GitLab offers incoming email where users can create issues, patches, and service desk by having a unique email address per project, for example, incoming+SOME_ID-issue@incoming.gitlab.com
, then emails are processed by mail_room
so that it creates issues, and other features (this is my understanding, please correct it if it's wrong).
With Cells we plan to have multiple isolated GitLab instances. This means that we are going to multiple multiple mail_room
queued processing the same email, and the project might not even exist in that cell.
Possible Problems
- Having multiple
mail_room
processes might read an email and doesn't process it.- This might not be a problem because each
handler
seems to validate if the project exists.
- This might not be a problem because each
- Having a single incoming inbox for all cells will reduce reliability.
Possible Options
- A mailbox per Cell
- We need to keep in mind in the future we want to have the ability to move the organization from 1 cell to another, this means that the email address will end up changing every time we move the organization which is a breaking change to our users.
- Single mailbox, multiple
mail_room
only processes emails for the projects they have access to.
