Postfix never sends mail *from* TCP 25 or TCP 587. These are receive ports. Outbound connections occur on high ports. You're not properly describing your use case, actually not at all. Would you please? Is this Postfix running on your desktop/laptop workstation and accepting mail from your MUA, or is it runing on a 'dedicated' MX MTA host? It's unclear how you are trying to use Postfix. Provide full 'postconf -n' output, never main.cf snippets. This was in your list welcome message. If you'd posted that we already have an answer for you. -- Stan
