Yes,
Foxmail for mac client, after dovecot upgrade from 2.1.17 to new version, imap can't receive any email, I perform packet capture test, foxmail will not have next step after sending {LIST "" *} command action.
Foxmail for mac client, dovecot version 2.1.17 can receive imap mail normally, because we need to add quota_max_mail_size configuration, we must upgrade to a higher version (https://wiki2.dovecot.org/Quota/Configuration# Maximum_saved_mail_size)
After comparison, the new version of dovecot returned without quotes.
I hope that the quotes can be changed in the configuration, can I?
Can I change the configuration to add quotes now?
Or add this setting in the next version.

Why is the quotation mark removed in the new version?
Because they were unnecessary. The code was changed to use more generic IMAP token writer, which adds quotes only as necessary.
Is there any configuration option in the new version to add quotes?
No. Does it break some client?
