# 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.
set mailman [new_CkMailMan]

# Set the SMTP server (obviously, use your SMTP server, not chilkatsoft.com)
CkMailMan_put_SmtpHost $mailman "smtp.chilkatsoft.com"

# Set the SMTP login/password (if required)
CkMailMan_put_SmtpUsername $mailman "myUsername"
CkMailMan_put_SmtpPassword $mailman "myPassword"

# Create a new email object
set email [new_CkEmail]

CkEmail_put_Subject $email "This is a test"
CkEmail_put_Body $email "This is a test"
CkEmail_put_From $email "Chilkat Support <support@chilkatsoft.com>"
set success [CkEmail_AddTo $email "Chilkat Admin" "admin@chilkatsoft.com"]
# To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

# To send high-priority email, 
# add the X-Priority header field with the value "1" 
# to indicate highest-priority.
# A value of "3" is normal, which is the same as not setting
# the X-Priority header at all, and "5" is the lowest. 
# "2" and "4" are in-betweens.

# Microsoft Outlook might add the following headers when
# sending high-priority email.

# X-Priority: 1 (Highest) 
# X-MSMail-Priority: High 
# Importance: High 

# The X-Priority header alone is enough to make the email high-priority.

CkEmail_AddHeaderField $email "X-Priority" "1"

# Call SendEmail to connect to the SMTP server and send.
# The connection (i.e. session) to the SMTP server remains
# open so that subsequent SendEmail calls may use the
# same connection.
