Yes, but a localhost SMTP server that KMail sends email to, and it manipulates
it and sends it to the server you want is indistinguishable from KMail. You
just send it to the server using SMTP to localhost (or /usr/sbin/sendmail,
etc.), it manipulates the message, and sends it on its way to the server that
is required (be it the company's SMTP server, your hosting's SMTP server, a
server in a different country, etc.).

So this server acts as an intermediate, transforming, proxy to the message
you've sent.

But there can be multiple To: addresses.

But how will they know that the messages had other recipients? If you specify a
"To:" or "CC:" it will get sent to them.

OK.

It wouldn't be ideal because Yosi won't know that the mail was sent to Gilad,
and vice versa.

OK.

Thanks, have one too.
