Hello folks I hope you all are doing great I just have a couple of questions, might sound like a silly question for everybody who knows about it, but honestly I don't know. Right now I'm working in a personal project and I need to know the answer of the questions below. 1. It is strictly necessary to install PowerMTA on Interspire or could be installed directly on VestaCP or ISPConfig 3.1 ? 2. Will PowerMTA (SMTP) works with SOCK5 proxies with 25 port blocked ? Thanks in advance for your help.
