Yes, please. I just upgraded to php 8.2 and hit the same problem. I don't know how to use ChatGPT or what to "ask" it.

JohnDoh:
Its not specifically a Roundcube issue. It has to do with PHP's intl extension and the version of ICU you have on your system. From https://www.php.net/manual/en/function.idn-to-ascii.php "Either INTL_IDNA_VARIANT_2003 (deprecated as of PHP 7.2.0) for IDNA 2003 or INTL_IDNA_VARIANT_UTS46 (only available as of ICU 4.6) for UTS #46."
