When are "Sent Items" and "Deleted" folders enabled?
The ability to use the "Sent Items" and "Deleted" folders is enabled only with IMAP service. By default, Plesk uses MailEnable standard edition, which does not support IMAP protocol, as a primary mail server.
To be able to use folders, including "Sent Items" and "Deleted" a mail server that supports IMAP service should be used.
IMAP service is supported by the following mail servers that can be used with Plesk:
- MailEnable Professional Edition
- MailEnable Enterprise Edition
- Merak Mail Server
- SmarterMail mail server
