Secure email

I have been looking at neomailbox and a few other "secure" web-based
email services.
Neomailbox: https://neomailbox.com/
A concern I have is protection against key loggers, packet sniffers,
and other methods for stealing my password.
Neomailbox talks about something called an iKey. Below is an excerpt
from their web site.
"When you choose the option to "Store password on iKey" in SecureBat!,
this will activate a hardware implementation of the CRAM-HMAC
Challenge/Response (RFC-2095) authentication. A special non-replicable
hardware token, iKey by Rainbow Technologies, is used to store the
password and to produce Keyed Hashing."
The above paragraph sounds good, but I know very little about these
things. Are there any disadvantages to using this hardware key?
Apparently, if I understand things correctly, it generates a unique
and usable "digest" password each time I log in. This "digest"
password can only be used once. Are there any loopholes that would
allow attackers to duplicate my hardware token?
Does anyone have opinions on secure email and/or neomailbox?
Thanks for any input!

Secure mail is generated locally using your private key to sign your
mails, and public keys of others to encrypt them. Things like
Neomailbox only secure the connections between you and the server.
That's it. Firstly, most email providers allow that, and secondly, it's
almost useless.
The reasons are simple: The administrators of Neomailbox are still able
to read your mails, as well as any other person potentially between
Neomailbox and the intended receiver. Even if the mail goes from a NMB
user to an NMB user, still the NMB administrators are able to read the
mails.
Use proper encryption and signature schemes. Have a look at PGP [1] or
GnuPG [2]. The latter is more difficult to use, but I trust it more
than PGP, for whatever reason. Maybe because PGP is an american
product, and because it's commercial (it's still free of charge).
However, that's a matter of taste.

Essentially the same useless crap as Neomailbox. You'll want to read
more carefully.
