Syntax: imap_capabilities extension ...; Default: imap_capabilities IMAP4 IMAP4rev1 UIDPLUS; Context: mail, server Sets the IMAP protocol extensions list that is passed to the client in response to the CAPABILITY command. The authentication methods specified in the imap_auth and STARTTLS directives are automatically added to this list if the starttls directive is enabled.
