I work for a fulfillment comapnay who processes orders for several clients.
Most of what I do is mergeing mailing lists to letters which get shiped with
items. However they want me to start sending e-mail to customers whos orders
are on backorder. I have developed a merge letter which i want to use and
have it working with e-mail merge. However I need to find a way to send these
e-mails so they do not come from my personal address. I thought of asking my
customer to set me up an account on their mail server but I dont believe
their exchange server is setup to allow connections over the internet. So is
there any way to "Spoof" the e-mail so it appears that its coming from my
customer and not our company.

Im shure there is a way to do this since i get 100's of spam e-mails from
places that im shure they didnt come from.
