FTP Mailbox: Security Tab

Note: This tab applies only to FTPs hosts.
Security Mode
Possible values:
  • None - For non-secure transfers, and commands and data are clear-text.
  • SSL Implicit - For servers that support only SSL connections.
  • SSL Explicit - For servers that support SSL by using either the AUTH SSL or AUTH TLS command. 
Client Certificate
If SSL Explicit or SSL Implicit is specified in the Host FTP tab, the target server can issue client certificates.  In this case, import the client certificate using Certificate management and then use the Certificate Alias and Password fields to specify (or browse for) the imported certificate.
