Regular expressions are extremely powerful - and complex. Fortunately, there are plenty of sources for good regular expressions that describe all kinds of patterns. This is how you turn a RegEx pattern into a regular expression engine:
$regex = [RegEx]'(?i)\s[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\s'
$regex now is a highly specialized filter for extracting e-mail addresses from text. Use this to list all emails in $text:
$regex.Matches($text) | Select-Object -ExpandProperty Value
