I'll have to look at other spams). In short: - 0.42% are >= 100K - 0.19% are >= 256K - 0.07% >= 1M so ther's not much benefit spending SA processing on large messages. ********************************************************************** Confidentiality : This e-mail and any attachments are intended for the addressee only and may be confidential.
