Sorry, it's how this list works. If you don't want that, there are
some options for majordomo you can set to alleviate the issue. I'm
not changing how I reply to the list just for you.

If you are storing credit card data then you must follow the PCI
standards for doing so. Look them up on the web and get a copy.
Failure to follow their security guidelines will result in you not
being allowed to process or handle credit cards.
That said, the best way to store them is to not store them. If you
still have to, then use some kind of encryption using the user's
password as part of the key, and don't store the user's password, only
an md5 of it. Also, store the password on one machine, encrypted, do
the encryption decryption on another machine.
