[horde] Tests fail to run with repo Horde/Mail

[Mike]

Ralf,

I had to apply: composer require horde/util:dev-FRAMEWORK_6_0#dd43607

In order to get rid of some failures that were present without it.

Also, I got the '/nonexistent/sendmail: not found' when running the tests:

vendor/bin/phpunit
PHPUnit 11.5.55 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.5.5
Configuration: /var/www/mail/phpunit.xml.dist

Time: 00:02.437, Memory: 18.00 MB

OK, but there were issues!
Tests: 403, Assertions: 669, Deprecations: 1, PHPUnit Deprecations:  
10, Skipped: 12.
