How to send a S/FAX over IP

The next evolution step after postage was FAX. FAX keeps the look and feel of your document and arrives on the recipient’s desk in a matter of minutes. Unfortunately the law in most countries does not accept a FAX as a legal relevant Document. Furthermore everybody knows the low quality and resolution of FAX transmitted documents.
With the next evolution step some disadvantages of FAX had been removed. Nearly everybody today can be reached via email. The introduction of the S/Mime standard removed one of the last remaining weak points of email. S/Mime allows you to digitally sign your correspondence. But while snail mail and FAX preserved the look and integrity of your original documents with the introduction of e-mail nobody knows the look of his email at the recipient’s end. But what happens if an architect wants to send a design to a customer? Most likely the customer will not have CAD software available to display the drawings! Furthermore did you ever think about what happens with the email once it arrives to its recipient? An email is unprotected and can be copied and printed without any limits. For example it is close to impossible to do a digital rights management (DRM) of your documents sent via email.
There is one other big problem that email is currently facing. SPAM! Long underestimated and just seen as an unwelcome noise it became a real threat to email communication. Along with this threat a number of SPAM filters were developed. Most SPAM Filters currently on the market are just content sorter. They sort HAM and SPAM after accepting the mail. But due to the large amount of SPAM nobody really bothers to review all emails which were classified as SPAM. This results in bad habits of deleting SPAM fully automatic. You as a sender would not get notified that your email got deleted as SPAM. That would work only if the recipient uses a SPAM Filter on protocol level which rejects SPAM with the reason of rejection before accepting it. Such Anti SPAM SMTP Proxies are very rare on the market.
