There is a disconnect between the way Postfix handles recipient_delimiter and the way Dovecot handles it. For Postfix, it is a set of delimiters that can each individually be used to separate the address from the . In Dovecot, having multiple characters in recipient_delimiters simply makes it a multi-character single delimiter.
For my purposes, the Postfix method is much more versatile. Extra delimiters can be added without breaking the way users currently have delimiters.
Objection: assumes facts not in evidence.
This is the way it is supposed to work now in dovecot, so, either it is now broken, was always broken (I haven't had an opportunity to test it since I was forced to migrate our email server to Office365 last year), or you are not doing it right.
But we'd need to see your config to make that determination...
