I scheduled a campaign with 6 of my PMTA servers but my scheduled campaign gets system paused, and give this error: SMTP failed: Expected response code 250 but got code "530", with message "530 5.7.0 authentication required in "MAIL from:<[email protected]>". I have to resume it every time it gets paused. Please, help me with it, and advice me about, why is this happening? This is very frustrating..
