- Plesk Onyx for Linux
Plesk still shows Courier-IMAP in Tools & Settings > Mail Server Settings after switching to Dovecot.
The following query also shows Courier-IMAP:
# plesk sbin mailmng --features | grep -i imap
$features['IMAP_POP3_Server'] = "Courier-IMAP";
$features['IMAP_POP3_Server_package'] = "courier-imap";
/usr/bin/deliverquota is present.
Connect to the server using SSH and remove the following file:
# rm -f /usr/bin/deliverquota
