Newbie seeks help setting up mailer in Cronicle

[DavidMatthewson]

Hi
I'm new to Linux and have installed Cronicle on a Mint box and it works fine. But I can't get the emailer to work. I've got NodeMailer installed and set up the config in Cronicle to use our SMTP server, but get an error:
Error

Failed to send e-mail for job: jm8ume4zo0f: [email protected]: Error: connect ECONNREFUSED 127.0.0.1:25

This is correct. If I telnet to 127.0.0.1 25 on the Mint box I also get refused.

I suspect I need to set up a 'transport' for nodemailer but can't see how to do that?

All suggestions much appreciated -0 thanks.

Well, these problems do not involve Cronicle per se. You just need help setting up your SMTP server, it seems.

I've got NodeMailer installed

You've got "Nodemailer" installed? Um........... why are you installing Nodemailer? It comes with Cronicle automatically. There's nothing to install. It's just an NPM module that Cronicle installs for you. This is a very confusing statement.

... and set up the config in Cronicle to use our SMTP server...

Okay, from this statement it sounds like you already have an SMTP server? But then you go on to say...

If I telnet to 127.0.0.1 25 on the Mint box I also get refused

So the question becomes, where exactly is your SMTP server running? Is it on the same server where Cronicle is running?

If so, then telnet'ing to port 25 on localhost should definitely work. If it does not, then your SMTP server is not actually running. Check the logs, check systemctl status, etc. Also, you can use tools like netstat -tuln to show all socket listeners. Look for a listener on port 25.

If your SMTP server is not running on the same box as Cronicle, then you need to change the smtp_hostname configuration property to the IP address or hostname of the server that is actually running your SMTP server.

If you need help setting up an SMTP server, check out this guide.

Good luck!

Thanks for the prompt & helpful reply.

I probably did not explain myself very well, so pls accept my apologies... and yes, my issues are SMTP related and not Cronical per se.

1. I thought I had to install NodeMailer myself - I did not realise Cronicle did that for me! (Duh!)

2. We have a working SMTP server on the LAN and I was trying to get the Mint box which has Cronicle to use that.

3. I can Telnet from the Mint box to the SMTP box on 25 fine, so that is good.

4. In the Cronicle config I have set smtp_hostname to the IP of the remote SMTP server. [I also tried FQDN - same result.]

Later.... OK, I've got it working thanks.

I had not understood that I needed to edit the config.json file - once I did this and correctly added the FQDN of the is working as it should.
