We have several people in our office with their own email accounts (different domains)who would like to have their messages branded. I'd like to set up our own server, and have the messages pass through, and the applicable HTML template applied to each message, based on the sender.
I know there are services that provide this, but at $140 each per year, I'd rather keep it inhouse. It seems most services have the clients change their outgoing mail server.
is this possible with sendmail, or am I on the wrong track? emailstationery.com or http://www.fabusend.com/
are some samples of what I'm trying to replicate
