Don't take this as doctrine, it's only what I've heard. But sendmail's 8.9
configuration to prevent unauthorized relaying requires that the sending
post office identify itself in the headers, I think. So, by trying to
remove their identification from the header you are trying to remove the
relaying security features that sendmail has been attempting to implement.
I would think that it would be less expensive to pay for an IP number at an
ISP with significant bandwidth and put your server there rather than paying
for them to host everything. All you have to do is find some place with an
available IP number to rent/sell/lease to you that has a permanent T1 or
better internet connection.

Hello,
I have a small web hosting company and I recently decided to give up
running a web/amil server out of my home (cable modem) and decided to go
with a 3rd party web hosting company and re-sell thei accounts under my own
name - a private label type thing.
My clients are supposed to be shielded from their presence - however after
I transfered my first domain there I found a problem with how they have
their email system set up. The reseller's domain appears in the email
headers.
(see example below - I've renamed the reseller domain and my domain)
Regards,
Mark

When I poked around a bit on my domain site I noticed they were using
procmail. I thought perhaps I could add something to the receipe which
would substitute my domain name for theirs? I have never used procmail but
think it's a possible solution. I need some help determining if it is in
fact a possible solution and if it is I'll need some help implementing it.
Here are the two files I found in my test domain...
/.procmailrc
RECIP=$1
MAILDIR=$HOME/testdomain-mail
INCLUDERC=.procmailrc
/testdomain-mail/.procmailrc
DOMAIN=(testdomain.org)
INCLUDERC=.rc.local.init
