Okay. ..I've looked at a lot of reselling opportunities and really like what I see with DonHost.
I know some people have had bad luck with them; but it seems to be from their lack of limiting plans.
The only thing I don't like about the DonHost plan is that they don't offer SMTP and have no plans to in the near future.

Does anyone know of any other reselling opportunities that share a similar pricing structure as DonHost; but will allow my clients to send mail from their domain?

i have expereince with few

host2own.com
cphosting.com
hostroute.com

they offer smtp but can not say they offer unlimited things

i have very bad experience with unlimited things :angry:
