Problem with the pmta script, I can't send emails?

Question

Email Marketing

Good afternoon! I am doing email marketing using the interspire program, the problem is that I installed the addon program powerMTA (Multiple Virtual PMTA) on the server,
this is a daemonized script.
The fact is that if powermta is disabled, then letters from the server leave, if it is connected, then it seems to be trying to send them, but in fact they are not reaching and I don’t even get into spam, what could be the problem?
