You did restart dovecot after that change? The changed setting is shown 
by doveconf -n even if you don't restart dovecot.

I just tried that here, the only difference is i'm using LMTP for 
delivery from postfix to dovecot.

As long as i have "recipient_delimiter = +" everything is ok and test 
mails are delivered from postfix to dovecot:

When i set "recipient_delimiter =" and restart dovecot the test mail is 
not delivered to dovecot:

i add the "+" back to the recipient_delimiter setting, restart dovecot 
and everything is back to normal...
