The Netscape Communicator and Mozilla browsers include support for email, and the ability to fetch mail through a POP3 server. Both products are available for a range of platforms, including Microsoft Windows and Linux.

Under some circumstances, malformed email messages may prevent Netscape and Mozilla clients from accessing POP3 mailboxes. In particular, users will be unable to access more recent messages or delete the malicious email.
