Yes. SlipStream Web Accelerator can reduce the amount of time it takes to send and receive email. SlipStream Web Accelerator accelerates email transparently without any user intervention, so you can use your mail program exactly as you normally would. It is compatible with any POP3/SMTP client, including Outlook Express, Eudora, Pegasus, Opera Mail, Mozilla Mail, and Netscape Mail. Email acceleration is disabled by default.
