Hi,

Recently, we faced an issue with dovecot. Mail delivered to New directory, but after we used Outlook to connect with POP3 protocol, there was no email delivered to Outlook and New/Cur directory was empty. If we don't use Outlook to connect, after a few minutes, it is empty also. Would you please help me to solve this issue?

Below is the result from "dovecot -n"
