Dovecot Quotas

Dovecot is an open-source IMAP and POP3 server for Unix-like operating systems, written primarily with security in mind. Timo Sirainen originated Dovecot and first released it in July 2002. Dovecot developers primarily aim to produce a lightweight, fast and easy-to-set-up open-source email server. The primary purpose of Dovecot is to act as a mail storage server. The mail is delivered to the server using some mail delivery agent and is stored for later access with an email client.¹

Within Dovecot you can set quota's. This custom integration will retreive these quota's and present them within Home Assistant.
