Hi I am having trouble with confirmation emails not arriving. It works locally in development with :

"Smtp": {
  "From": "noreply-DEV@devdomain.tld",
  "DeliveryMethod": "SpecifiedPickupDirectory",
  "PickupDirectoryLocation": "C:\\DEV\\Emails"
}

But on server with

"Smtp": {
  "From": "noreply-TEST@stagingdomain.tld",
  "DeliveryMethod": "Network",
  "Host": "192.168.101.233"
}

Nothing seems to happen. I am looking in back-office -> Settings -> log viewer but I can't see any errors or warnings. What should I look for if I suspect there is an smtp issue? I have checked that the confirmation email template is selected for the store and the path is correct.

Do you have an SMTP server setup on that IP? Where did you get those details? On most hosts i tend to use a service like Send Grid or similar to handle emails. There's a recent thread with people discussing Send grid like services with a free tier - try that.

I do not know the details of the smtp server implementation, only that these details work on other sites. I will reach out to the admin for the server and see if they can trace an attempt to connect/send.

Are other sites .net core? I have a vague recollection of some default changing. Try: "EnableSsl": "true"

Thanks I'll give it a go.
