dovecot - Jan 2014 - recipient_delimiter -- feature request

Hi,

It would be nice if the recipient_delimiter configuration option 
supported multiple recipient delimiters as Postfix now does.
e.g. now if I set: recipient_delimiter = +-  in Postfix, then 
test-extension at sample.com and test+extension at sample.com are both
recognized.
But if I set: recipient_delimiter = +- in Dovecot, neither of the above 
are recognized and instead test+-extension at sample.com is valid.

Well, presently this feature isn't that important to me, but I imagine 
it could be a source of confusion for people who are migrating from say 
qmail to postfix (as I am doing) and notice Postfix's cool ability to 
support both types of delimiters and assume Dovecot will as well (as I did).

Thanks,
Andrew Ray

To make it work the current way, is simple.

I would love for it though, to lookup and see if an mailbox exists  
with the delim first, then if it doesn't lookup just the username part.
