Hi there!
I compiled dovecot from git on 5.2.2018.
The id of the last commit is:
$ git log --format="%H" -n 1 83b1300b96e753206f9226e3738a7ad9f5428a75
From https://github.com/dovecot/core.git
There is a new error, when i try to open a virtual folder for my archiv (almost 30.000 mails) in thunderbird, also in k9-mail on android.

The systemd-Unit for my self-compiled dovecot has set some ulimits, because i got problems on a large amount of mails with doveadm, increasing the ulimit avoid this problems:
