dovecot - Sep 2019 - [Bug] Sieve vacation :addresses match only case-sensitive?

The recipients in the vacation :addresses String list are matched 
case-sensitive.

If the recipient gets a mail with wrong case, the message is discarded with:
"discarding vacation response for implicitly delivered message; no known 
(envelope) recipient address found in message headers"

I think the matching should be case-insensitive.

Is this a bug or do I miss some option?

I'm using Dovecot 2.3.7.2, Pigeonhole version 0.5.7.2.

Further investigation showed me that it has to be a bug.

I tested with Dovecot 2.2.36.3 (a7d78f5a2), Pigeonhole version 0.4.24 
(5a7e9e62):

In this version the additional addresses in vacation :addresses 
["test at example.com"] are handled case-insensitive.

In the new version: Dovecot 2.3.7.2 (3c910f64b), Pigeonhole version 
0.5.7.2 (7372921a) installed via https://repo.dovecot.org/, (same sieve, 
same configuration) these addresses are handled case-sensitive.

The case-sensitive matching of mail addresses, doesn't make any sense to me.

Could someone confirm this behavior?

Kind regards

Philipp

Isn?t RFC-compliant behavior to treat the local part as case-sensitive and
the domain-part as case-insensitive?
