Thank you, excellent DKIM plug-in
Needs a little prior knowledge about what you are trying to achieve. That said, it's a brilliant plug-in and not only does it DKIM sign, it's creates and signs using a 2048 bit key pair. The interface is quietly elegant and has a beautiful simplicity to it. Thank you so much. I've just installed on WordPress 6.9 and it's working a treat.

Awesome tool for getting formmail working
I've been struggling for weeks trying to get my sites formmail to send and be received in the inbox and not go straight to spam. I've tried multiple plugins all promising to fix this problem but it was this plugin which did the job. Not only does it show you the state of each test (DKIM/SPF) but it shows you the server responses and allows the creation of new DKIM keys and the actual TXT details to be added to DNS. It did take a few hours of playing but then it just worked and emails being sent from my website are now arriving in the correct email inbox with the correct headers.

Very helpful plugin that adds a key feature to WP
Great plugin that allows signing emails sent by your website (e.g. contact forms) and also assists in the configuration of SPF/DKIM/DMARC (even though much simplified with the plugin, the overall topic is not dead simple and will require you delving a bit into it) to make sure they are delivered to major email providers (otherwise emails may simply never reach the recipient, not even in the spam folder).Backend operations are performed locally on your Wordpress instance, which is great privacy-wise.

the KISS way of WP email authentication
Finally a really simple way to use DKIM on my site's emails. Took me a moment to understand that I had to create my own DKIM selector in the plugin and add it to my DNS records (where I already had a "default" DKIM configured for every mail going through my SMTP server); once that was done the rest worked automagically. Sure, the other option would have been to export my private "default" DKIM key and import it into the plugin. My only remaining gripe is that this plugin somehow does not yet play well with ContactForm 7.
