Because of the event handler, right after the creation of the SSL the task for SNI is started. I will monitor it for the next couple of days if it is working as expected.
And what do you mean with active autodiscover?
Let me know how it works on you're Plesk server
We are not able to have an automatic let's encrypt creation (in a new subscription and in an yet created subscription)...
I have created an new suscription that correct point to ip server and working, but none of SSLit cron create the SSL automatically (I execute then from plesk crontab page directly) :
/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/sslit/scripts/keep-secured.php'
/usr/local/psa/admin/bin/php -dauto_prepend_file=sdk.php '/usr/local/psa/admin/plib/modules/sslit/scripts/complete-order.php'
So also active SSL mail server subscription by events will not work for us...
About autodiscover, I see that by default now, as it is active on server wide, it also active automatically on new subscription option
But no option to create it automatically on a yet created subscription, only had to be manually by plesk mail subscription tab....
