Get-POP Cmdlet
Parameters Output Objects Configuration Settings
The Get-POP component is used to retrieve electronic mail from Internet Post Office (POP) servers.
Syntax
Get-POP [parameters]
Remarks
This cmdlet implements a standard Internet Post Office (POP3) client as specified in RFC 1725 for retrieving email messages.
To use the cmdlet to retrieve email, you must specify a mail Server and Credential. If the View parameter is set, the specified message will be retrieved in EmailMessage.
If View is not set, the cmdlet will retrieve a list of the messages on the server in one or more MessageHeaderss.
To use SSL-enabled (RFC 2595) POP, set SSL to True.
This cmdlet handles retrieving emails and listing email folders. To send an email, see the SEND-EMAIL cmdlet.
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.
# list the last 10 messages to arrive get-pop -server mailserver -credential $cred -list 10 # view message number 43 get-pop -server mailserver -credential $cred -view 43
Connection Handling
This cmdlet supports persistent connections through the Connection parameter. To establish a new POP connection, use the Connect-POP cmdlet. To close the connection, use the Disconnect-POP cmdlet.
