Send-Email Cmdlet
Parameters Output Objects Configuration Settings
The Send-Email cmdlet is used to send Internet mail using the SMTP protocol (the Internet mail standard).
Syntax
Send-Email [parameters]
Remarks
This cmdlet implements a standard SMTP client as specified in RFC 821, and also supports the SSL-enabled equivalent (RFC 2487). To send a message, set the Server, To, Subject, From, and Message parameters.
Additional recipients can be set with the CC and BCC parameters. To specify multiple recipients, in the To, CC, and BCC parameters, simply specify the destination email addresses separated by commas.
One or more attachments can be added by setting the Attachment parameter. HTML Messages may be sent by setting the MessageHTML parameter.
SSL communications are supported. When communicating with an SSL server, set the SSL parameter. If authentication is required, set the Credential parameter.
The cmdlets support pipeline input for some of their parameters. Prebuilding an object and piping it to the cmdlet is very useful, but should be used with caution to prevent security conflicts. Steps have been taken to decrease the risk of a possibly accidental pipe to the cmdlet, for instance, the Credential parameter cannot be piped to the cmdlet and must be specified manually.
# Send a simple messagesend-email -server myserver -from myuser@mydomain -to friend@domain -subject "my subject" -message "message text" -attachment "C:\test.txt"# Send an HMTL messagesend-email -server myserver -from myuser@mydomain -to friend@domain -subject "New subject" -messagehtml "<b>HTML</b> Message"Connection Handling
This cmdlet supports persistent connections through the Connection parameter. To establish a new Email connection, use the Connect-Email cmdlet. To close the connection, use the Disconnect-Email cmdlet.
