We currently have external email members of groups containing + and / characters (e.g. user+task1@example.com). This has worked fine for a long time. However, when I tried to add a new external mail member with a + or / character recently, Google Workspace rejected this. When I tested out the latest version of GCDS (4.7.18) on our existing groups, I get the following message:
Group member "user+task1@example.com" excluded from group "currentgroup@
mydomain.com", as it contains characters not allowed in an email address.
This is very concerning since + and / are perfectly legal characters in an email address. What's more, Google *recommends* the use of + characters for task-specific email addresses:

Can someone help me understand why Google Workspace is disallowing + and / characters in email addresses? Can we get these characters allowed again?
