IMAP STARTTLS (Explicit TLS/SSL)

The StartTls property is set to force the Connect method to automatically convert an connection to TLS/SSL via the STARTTLS IMAP command.

This is also known as "explicit TLS/SSL" as opposed to "implicit TLS/SSL". With implicit TLS/SSL, the IMAP client connects on the well-known IMAP TLS/SSL port 993 and the secure channel is immediately established. With explicit TLS/SSL, the IMAP client connects on the typical non-secure port (143 usually) and the converts the connection via the STARTTLS command.

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$imap = chilkat::CkImap->new();

# Indicate that STARTTLS should be used to convert
# to a secure TLS/SSL connection:
$imap->put_StartTls(1);
$imap->put_Port(143);

# Connect to an IMAP server and convert the connection
# to TLS/SSL via STARTTLS.
$success = $imap->Connect("imap.example.com");

# The remainder of this example is the same as for 
# non-TLS/SSL...
