Hi all,

I've got a citadel email server running on my raspberry pi along with Node-Red running Pi OS Lite.

Node-Red v3.0.0  
Node.js v18.6.0

Every time I try to read email from the local Citadel server via pop3 or imap node-red hard crashes with this error:

```auto

nodered.service: Failed with result 'exit-code'.
nodered.service: Consumed 12.748s CPU time.

```

I've tested this on my Windows PC connecting to the mail server on my raspberry pi and it works fine. My pc is running Node-Red v2.1.4 and node.js v16.15.1

Does anyone have any idea how I could solve this bug, or is it impossible to run an email server and Node-Red on the same machine?

Thanks,  
Toby

What version of node-red-node-email-variable are you using? The current is 1.0.6

I see you are using node.js 18 which, unless I have missed an announcement, is not yet recommended, though I suspect that is not the issue. [Supported Node versions : Node-RED](https://nodered.org/docs/faq/node-versions)

I'm using the latest version of node-red-node-email-variable. I changed to that for troubleshooting purposes in case it was the node-red-email palette which had the same issue. To be clear it occurs in both:

node-red-node-email-variable v 1.0.6  
node-red-email v1.15.1

I'll downgrade node.js anyway just in case it's that.

Either way it would be worth submitting an issue about it, unless someone sees it here and announces a fix. Soon nodejs 18 will be supported, I expect, so the developers will want to know about any issues with that.

Thanks! it did end up being a nodejs version issue, but I'll submit it to github anyway.
