I am trying to receive an email message with a .txt attachment. The email is received and the body of the email displays the data from the .txt file but I really need the attachment adding not being in the body of the email.
I have an issue also as I am using the Siemens IOT2050 and its limited to Nodered v12.22.5
I am certain you realises this but for anyone following along: The better option is to move to a device that gets support / gets updates. The Revolution PI is once such industrial option. They are fast, reasonably priced and receive regular updates. You can even just update Node/Node-RED yourself.
Node V12 is End Of Life and which could end up being a significant security risk. If not security, certainly a compliance issue. Installing old versions of software is also risky since they were likely updated to patch CVEs or other security issues.
