Capability xsender Option

Deleted in release: 8.0

The  IMAP option, when set to   (the default), causes the IMAP server to advertise the XSENDER IMAP extension. In version 8.0 and later, the XSENDER feature was removed from imapd and this option has been deleted. DELETED: simplify message store by removing non-standard feature.

Important note: If the MMP  option is explicitly configured, it is critical that XSENDER not be included in the value for MS 8.0 and later, as this can lead to clients trying to use the capability and failing. Similar considerations apply to third-party IMAP proxies that advertise a fixed set of capabilities.

The default value is: 1
