Further investigation showed me that it has to be a bug.<br class="">
<br class="">
I tested with Dovecot 2.2.36.3 (a7d78f5a2), Pigeonhole version 0.4.24 <br class="">
(5a7e9e62):<br class="">
<br class="">
In this version the additional addresses in vacation :addresses <br class="">
["<a href="mailto:test@example.com" target="_blank" class="">test@example.com</a>"] are handled case-insensitive.<br class="">
<br class="">
In the new version: Dovecot 2.3.7.2 (3c910f64b), Pigeonhole version <br class="">
0.5.7.2 (7372921a) installed via <a href="https://repo.dovecot.org/" rel="noreferrer" target="_blank" class="">https://repo.dovecot.org/</a>, (same sieve, <br class="">
same configuration) these addresses are handled case-sensitive.<br class="">
<br class="">
The case-sensitive matching of mail addresses, doesn't make any sense to me.<br class="">
<br class="">
Could someone confirm this behavior?<br class="">
