Plus Addressing with dovecot does not work

[xurubo93]

I read about plus addressing and found it very helpful for some reason but cannot get it to work.

I did the following configuration:

1. Postfix
   in the /etc/postfix/main.cf I added the following configuration parameter
   recipient_delimiter = +
2. Managed a sieve script in webmail which contains the following:
   1: # Sieve Filter
   2: # Erzeugt von Ingo (http://www.horde.org/apps/ingo/) (03.02.2015, 02:53:39)
   3: require "fileinto";
   4: # Plustest
   5: if address :all :comparator "i;ascii-casemap" :contains "To" "+plustest" {
   6: fileinto "INBOX.plustest";
   7: stop;
   8: }
3. I created a folder in my INBOX with the name plustest

now I sent me an email from an outside freemail-account to see if it works. In the logfile /var/log/maillog I can see the following entry:

Feb 3 15:06:25 mail postfix-local[18290]: cannot chdir to mailname dir <name>+plustest: No such file or directory
Feb 3 15:06:25 mail postfix-local[18290]: Unknown user: <name>+plustest@<dom.tld>
Feb 3 15:06:25 mail postfix/pipe[17708]: 0ECAF4C1B3: to=<name+plustest@dom.tld>, orig_to=<aliasname+plustest@dom.tld>, relay=plesk_virtual, delay=0.61, delays=0.52/0/0/0.09, dsn=2.0.0, status=sent (delivered via plesk_virtual service)

I changed my real name to <name> and my domainname to <dom.tld> in this post.

What did I do wrong?
