Pascal (Lazarus/Delphi)

IMAP Capability

Demonstrates how to send the CAPABILITY command to request a listing of capabilities that the IMAP server supports. A capability name which begins with "AUTH=" indicates that the server supports that particular authentication mechanism. Pascal (Lazarus/Delphi)
