Database is better.
I just make this to see what tls versions that was used before I updated to the HMS with TLS 1.3.

Been running 5.6.8 for a long time now. Switched off TLS 1.0 and 1.1 last year.

I don't have enough traffic to justify large scripts

With the database my data is always updated and I can simply do a query from SQLyog

Someone like @palinka would wrap a webpage around it

"oMessage" is a reserved word. You CAN use it but eventually you will need it for something else :wink: Also, there is NO built in Shell object (WShell) in the script engine that hMailServer is using. You will have to declare it yourself. Check the scripting section of the forum, there are hundreds ...

OK. But these e-mails are spam or addressed to users that have been deleted. These emails must be deleted, and the sender must be informed about the delivery error.

Exactly. So... back to the OP's request to reject before downloading the message...
