Quoted local parts are allowed in email addresses, so the above are
probably not valid, but "Useruser"@example.com or
"User\"user"@example.com are valid.

It's as I suspected. The various input tags on the Membership list look

<INPUT name="user at example.com_unsub" type="CHECKBOX" value="off" >

where user at example.com is the email address. Clearly, if the address
contains double quotes, the field name gets truncated or garbled, so
it isn't possible to change anything for this member from the
Membership list page..
