SMTP using HTTP Proxy

Demonstrates how to communicate with an SMTP server via an HTTP proxy. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

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

# The mailman object is used for sending and receiving email.
$mailman = New-Object Chilkat.MailMan

# To connect through an HTTP proxy, set the HttpProxyHostname
# and HttpProxyPort properties to the hostname (or IP address)
# and port of the HTTP proxy.  Typical port numbers used by
# HTTP proxy servers are 3128 and 8080.
$mailman.HttpProxyHostname = "www.my-http-proxy.com"
$mailman.HttpProxyPort = 3128

# Important:  Your HTTP proxy server must allow non-HTTP
# traffic to pass.  Otherwise this does not work.

# Set the SMTP server.
$mailman.SmtpHost = "smtp.chilkatsoft.com"

# Set the SMTP login/password (if required)
$mailman.SmtpUsername = "myUsername"
$mailman.SmtpPassword = "myPassword"

# Create a new email object
$email = New-Object Chilkat.Email

$email.Subject = "This is a test"
$email.Body = "This is a test"
$email.From = "Chilkat Support <support@chilkatsoft.com>"
$success = $email.AddTo("Chilkat Admin","admin@chilkatsoft.com")

# Call SendEmail to connect to the SMTP server via the HTTP proxy and send.
# The connection (i.e. session) to the SMTP server remains
# open so that subsequent SendEmail calls may use the
# same connection.  
$success = $mailman.SendEmail($email)
if ($success -ne $true) {
    $($mailman.LastErrorText)
    exit
}

# Some SMTP servers do not actually send the email until 
# the connection is closed.  In these cases, it is necessary to
# call CloseSmtpConnection for the mail to be  sent.  
# Most SMTP servers send the email immediately, and it is 
# not required to close the connection.  We'll close it here
# for the example:
$success = $mailman.CloseSmtpConnection()
if ($success -ne $true) {
    $("Connection to SMTP server not closed cleanly.")
}

$("Mail Sent!")
