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