Multiple recipient delimiter support?

[Tanstaafl]

Trying to find out if dovecot supports the use of multiple recipient
delimiters, as postfix does, but can't find an answer...

The wiki only mentions it in two meaningful places (that I can find)...

With respect to postfix:
/wiki.dovecot.org/LDA/Postfix

The above seems to imply that for postfix/LDA all I need to do is define
it in postfix (which supports multiple recipient delimiters).

And with Pigeonhole/Sieve:
wiki.dovecot.org/Pigeonhole/Sieve/Configuration

It seems to be saying that I must also define the same
recipient_delimiters in dovecot config if using LMTP, and also if I want
to use sieve for filtering of mail.

But, the example and text says nothing about the use of multiple
delimiters...

So, is this supported? If so, the wiki should be updated to reflect this...
