Only the newest 7.x version 7.2 has an internal Mail client. Version
18.104.22.168 is browser-only version. Version 7.2 has unpatched, confirmed

released to fix them.
Your report will never reach Netscape due to non-working security [at]
netscape.org (please read instructions to contact the vendor below).
