powershell - Use Read-Host to enter multiple lines

Question

Is there a way to use the Read-Host cmdlet to capture multiple lines?

My current approach is a bit awkward (and doesn't really work):

PS> Send-MailMessage -SmtpServer 'smtp.domain.xxx' -From 'First Last <flast@domain.xxx>' -To 'First Last <first.last@company.com>' -Subject 'Testing' -Body (Read-Host 'Enter text')
Enter text: line one `n line two `n line three

Resulting email body isn't three lines:

line one `n line two `n line three

Answer 1

while (1) { read-host | set r; if (!$r) {break}}

empty line finishes the input.
