After the latest Plesk and Dovecot update, I had to rewrite a few configs but with my custom config I struggle a bit. After a few hours without any issues, all the clients suddenly stopped working and cannot fetch or connect to the server.
On my server there are about 250 mail accounts active...
As I already posted a suggestion for Passkey, I want to make a short poll about it and want to advertise this suggestion as Passkey is the highest security method.

It's not only a Thunderbird issue as the mail encoding issue also exists in Apple Mail, Roundcube, Gmail. Maybe Office365/Outlook/Live handles the En/Decoding more ›failsafe‹.
Oh men (and ladies), I've wasted hours and days finding a solution with the support guys from the billing company Fastbill and my hosting provider HostEurope and both told me they can't see a problem in their billing php code or server wide until the guys from Danami sent me this conversation...
As I tried this setup on my own it's also not possible to install more than one email alias when installing with profile method. Or has this 'bug' already been fixed by Apple?
