I have on my server about 40 domains. And there is a problem with them in briefcase but not with my primary domain (hostname). First my hostname was xxx.com , now is mail.xxx.com. And downloading files from briefcase from account e.g. email@example.com is working! , url to file in briefase is https://mail.xxx.com/home/[...], but.. on account with any other domain eg. firstname.lastname@example.org not work! because url is http://mail.xxx.com/home/[...]. And when You click on this url You'll be redirect to zimbraWebClientLogoutURL. My question is .. why for other domains url is broken and begin with http , not https ???
