How to download webmail locally and encrypting it

We work mostly at customer site on their PC.
and we have a webmail but it is exploding in size.

We'd like to download all the old mails
onto the customers' PC in a very secure ant encrypted way so that they
won't be read by anyone else but us.

It also needs to be fairly easy and quick to retrieve the encrypted
mails when needed.

Any hint ?

Regards

This is a MIME GnuPG-signed message. If you see this text, it means that
your E-mail or Usenet software does not support MIME signed messages.
The Internet standard for MIME PGP messages, RFC 2015, was published in 1996.
To open this message correctly you will need to install E-mail or Usenet
software that supports modern Internet standards.

Nope.

You may be surprised to know that there is no universal protocol for
downloading E-mail messages from every webmail software on every possible
platform, in existence. I'm sure that this is possible, but the exact
solution depends on the specific software that you're using.

If it's a *public* webmail system (i.e. Yahoo, Gmail, etc.) then
things like FreePOPs [1] or YPOPs! [2] can solve the download part.
However I think the combination of "customer" (i.e. professional use)
and public webmail is unlikely.

In any case, most software which can download e-mail messages uses
temporary files (and/or the anti-virus mail scanner uses temporary
files). If these temporary files are intercepted, accidentily left
behind, etc., any *later* encryption is rendered useless. So the email
messages should be encrypted, *before* they are downloaded to the
customers PC, and even then temporary files, swap file/space, etc.
remain a security risk.

You (the OP) may want to cross-/re-post this to comp.security.misc.
