[Plugin: Configure SMTP] From field is incorrect

I wish the developer, or someone with the coding know-how, would address this issue. A seemingly minor fix would save users bundles of time by avoiding self-replies, forcing copy/past of actual site visitor’s email to address line, etc.

It’s up to whatever contact form plugin or custom code that you are using to override the “from” field for emails that it sends out. The Configure SMTP plugin doesn’t know anything about the contact form implementation that may be in use; it is simply a tool for configuring the SMTP server and making some capabilities available to other code/plugins.

Bear in mind that some mail servers will not accept for delivery any emails where the “From” email isn’t based on a domain they host, so doing what you request would cause issues for some people (possibly including yourself).
