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. > On 21 Mar 2019, at 6.22, lty via dovecot <dovecot@dovecot.org> wrote: > >> dovecot version >> >> v2.2.29 >> >> v2.2.36 >> >> v2.3.5 >> >> LIST "" * The returned mailbox does not display quotes >> v2.1.17 >> >> LIST "" * The returned mailbox shows quotation marks >> >> Why is the quotation mark removed in the new version? > > Because they were unnecessary.
