[feature-request] More useful error messages when sending mail fails
When sending an email fails a general "Problem sending mail" (or something like that) is shown. As the user it's pretty hard to guess what should be done in order to get the mail sent.
Just recently I got into this situation. I found this answer and set the logging on. That revealed the problems.
The first one was that the server certificate wasn't accepted (perhaps the root certificate isn't in the accepted list or something). I got rid of that by accepting untrusted certificates in the settings.
The second problem was that the server refused the sender address. It turned out that I had it incorrectly typed in the settings. So I fixed that too. After this mail was sent successfully.
Both of these errors were such that proper error messages could lead the user directly to the problem. Now I had to dig these out from the logs which is something a general user shouldn't need to do.
So I propose that more useful error messages are added to the email application. The two examples I gave above are just examples. I guess the developers can come up with more.
