The product is very useful. I tried connecting Thunderbird with the client’s server some time ago, and it took ages to realize that Thunderbird transferred authorization data as uncoded. At the same time, the user’s server waited for data in BASE64. As I see, I could solve that issue much faster with the aim of SMTP Proxy. Thank you for creating such a helping hand! Are you going to add any extra features to it later?

This looks like a great resource for troubleshooting SMTP issues. Does it also provide suggestions for fixing common errors? I'm thinking of errors like authentication failures, port mismatches, and SSL configuration issues.

@alexpetrov Thank you for your support! As for your question, you will see precisely what's wrong with your connection (authentication failures, port mismatches, and SSL configuration issues, as you mentioned), and that will point out where to fix the problem. As for the direct suggestions, unfortunately, we can't give specific tips since it's very individual depending on the solution for the SMTP connection you use, but knowing the exact errors for your SMTP provider's support, it will be easier to suggest to you what to do next. And if you need a reliable SMTP provider with a responsive support team, I can advise you of one. ;)

Alex and Valeriia, congrats on the launch! Your tool is a real time-saver! I’m setting up an SMTP connection to send emails via WordPress using the customer’s SMTP server. All day, I couldn’t realize why the emails weren’t sent. With the aim of SMTP Debug, I’ve discovered that the port I used in the settings was closed on the customer’s server’s side. That was a natural relief, helping me to move further with my task.
