This idea has been merged into another idea. To comment or vote on this idea, please visit DOMINO-I-1198 Support of Subaddressing RFC 5233 for Domino Mailserver.
Need support to use "email-sub-addressing" (https://docs.gitlab.com/ee/administration/incoming_email.html#email-sub-addressing) in the mail address field.
Sub-addressing is a mail server feature where any email to
email@example.com will end up in the mailbox for
firstname.lastname@example.org . It is supported by providers such as Gmail, Google Apps, Yahoo! Mail, Outlook.com, and iCloud, as well as the Postfix mail server, which you can run on-premises.
