Uff,
I quote:
E-mail protection consists of two independent modules; first, there is a generic scanner working on the SMTP/POP3/IMAP4 protocol level. It is capable of protecting any existing e-mail client that uses these protocols. Second, there is a special plugin for MS Outlook/Exchange only; it is completely transparent, requiring no special settings.
Typically, these protocols are used by: Eudora, Pegasus Mail, Netscape Mail, Mozilla Mail, IncrediMail and The Bat!
Hope this helps.
