Microsoft Exchange & Google Groups now supported by GitLab

This post details the addition of support for Microsoft Exchange and Google Groups as email servers for self-managed GitLab instances. This enables features dependent on incoming email, such as replying to notifications, creating issues/MRs via email, and Service Desk functionality, for users whose email servers do not support sub-addressing but do support catch-all mailboxes. This expands the compatibility of GitLab's incoming email features.
