# and sending (SMTP) email.

# To use a SOCKS4 or SOCKS5 proxy, simply set the following
# properties prior to making any calls that communicate with
# a POP3 server:
# The SOCKS hostname may be a domain name or 
# IP address:
CkMailMan_put_SocksHostname $mailman "www.mysocksproxyserver.com"
CkMailMan_put_SocksPort $mailman 1080
CkMailMan_put_SocksUsername $mailman "myProxyLogin"
CkMailMan_put_SocksPassword $mailman "myProxyPassword"
# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
CkMailMan_put_SocksVersion $mailman 5
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Set the POP3 server's hostname
CkMailMan_put_MailHost $mailman "pop.example.com"

# Set the POP3 login/password.
CkMailMan_put_PopUsername $mailman "myLogin"

# into a bundle object.  The email remains on the server.
