' To use a SOCKS4 or SOCKS5 proxy, simply set the following
' properties prior to connecting with the IMAP server:
' The SOCKS hostname may be a domain name or 
' IP address:
imap.SocksHostname = "www.mysocksproxyserver.com"
imap.SocksPort = 1080
imap.SocksUsername = "myProxyLogin"
imap.SocksPassword = "myProxyPassword"
' Set the SOCKS version to 4 or 5 based on the version
' of the SOCKS proxy server:
imap.SocksVersion = 5
' Note: SOCKS4 servers only support usernames without passwords.
' SOCKS5 servers support full login/password authentication.

' Connect to an IMAP server through the SOCKS proxy.
' Use TLS
