I have received email from an external person addressed to x&y@domain.com instead of xny@domain.com. (& is a valid character in email addresses.) It is caught in the catchall and I would like to add it as an alias/nickname of xny@domain.com but it isn't allowed. I'm thinking of putting a forwarding rule in the catchall, but this requires the user to click and approve.
Are there any other options?
For instance, the x+y@domain.com routes to x@domain.com automatically, but this doesn't seem to do that since both x@domain.com and y@domain.com already route to xny@domain.com as nicknames/aliases.

There is a difference in policy when it comes to regular Gmail and Google Apps.
While in regular Gmail, you can use most symbols such as
@,&,%, and+, these cannot be used in a Google Apps account.Google Apps Guidelines: https://support.google.com/a/answer/33386?hl=en
