Hi there, i send about 4 million emails per day and i use PowerMTA plus desktop mailer, the best thing about the desktop mailer is that it does not bring any thing suspecious code with itself.
gmail / hotmail / yahoo marks emails from interspire as spam because large isps have marked emails from these softwares spam
i am expert in PowerMTA
What volume of emails you want to achieve per day? or adnan.ahmed227 @ for further discussion.Does this still work?
