Shared Folders with +delimiter, wallace, stuck mails, possible solutions?

Good day,

when addressing mails to a shared folder and using the + delimiter, the 
mail does not get refused, it gets stuck in wallace.
it seems postfix does not accept it:

2019-02-22 14:22:32,774 pykolab.wallace ERROR [2286] SMTP Recipient(s) 
SMTPRecipientsRefused({'"shared+shared/sysadmin at domain.tld+nope"@domain.tld+nope': 
(401, '4.1.3 Bad recipient address syntax')},)

Now, best case scenario would be when the delimiters would work even 
with delimiters, but I dont know if that is realistic and how long it 
might take to implement that. I would have no idea where to start.

Now, if the mails cant be put in their respective folder, the mails 
should be at least delivered.

If there are certain edits I can make in config files, Ill happily try 
them out - today.

But if this needs a fix, I propose that wallace could rewrite the 
receiver line so the delimiter is removed and the mail can be delivered.

would be nice to address this silly delimiter shared folder problem once 
and for all...
