[qam] test fails in evolution_setup_servers - dovecot not installable
After https://progress.opensuse.org/issues/56273 got fixed, the evolution_setup_servers is now failing, a rerun done first at https://openqa.suse.de/tests/3397700 and a newer one at https://openqa.suse.de/tests/3424806
"No provider of 'dovecot' found." at https://openqa.suse.de/tests/3397700#step/evolution_prepare_servers/18
qam-regression-message is currently disabled, https://progress.opensuse.org/issues/57260 is about re-enabling it once the issues are all fixed.
