Rickard,
How are we all able to communicate on this list? Did we all have to download
and install an E-mail translator for each other's Email software? I happen
to be using Microsoft Outlook to formulate this response. I'll bet that
there are people using things like Lotus Notes to read this message.
Wouldn't it be a pain to have to install a plug-in (build and embassy) for
each different vendor's email products? Isn't it convenient that by virtue
of having a common, well defined wire protocol for email that I can
communicate directly with you with no extra set up and not having to trust a
plug-in not to have a virus of some sort in it?!
Being a financial institution, we have a long standing policy against
accecpting and running code from external sources. Its much more difficult
to do damage with a packet of data over a wire protocol.
