Error: connect ECONNREFUSED 192.168.0.16:9990

[jethr0-1]

I am trying to run an SMTP server with the following options:
maildev --ip 192.168.0.16 --outgoing-port 9990 --outgoing-host 192.168.0.16

It seems to run fine at first. Sending emails through port 1025 appears in the web interface. But when trying to relay the emails it spits out the following error:

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: connect ECONNREFUSED 192.168.0.16:9990
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1107:14)

    at emitErrorAndCloseNT (internal/streams/destroy.js:59:3)
    at process._tickCallback (internal/process/next_tick.js:63:19)

And on the web interface it says "Relay failed: undefined"
Does anybody know the fix to this?

It's saying that the connection is refused (ECONNREFUSED). What do you have running on port 9990 to receive the relayed emails?

Nothing is running on port 9990 except the --outgoing-port option set in the command

[kgeis]

The outgoing host/port settings are to indicate the mail server that you are relaying to. It is expecting that you have a mail server running on 192.168.0.16:9990, and because there is nothing running, the connection is refused.

Ahh I see, thank you. I will try without the outgoing port

But now when I send an email to myself through my SMTP server it doesn't show up in my inbox. Have I missed an option or argument or something?

I'm not sure I can help, but can you rephrase that to be more clear? Does "my SMTP server" mean your instance of MailDev or another email server? Is "my inbox" in MailDev or on another server?

Can you relay without a MailDev error when you set the other server as the outgoing?

Sorry, there is no other server, I only have MailDev. I found out what the problem could be:
Apparently, my ISP blocks port 25 on all residential networks, meaning that it's impossible to run an SMTP server from home. I'm going to call them and inquire about getting it unblocked today
