Simply the best

I install this plugin on every website as it’s the only one with logs and fallback server. So I can have SendinBlue without their plugin (don’t use newsletters, only transactional emails) and in case it can’t be used for delivery, my own SMTP server is used. It works great. Only issue I have is problem with sending emails to non-existing addresses as this prevents sending email completely (would be nice to have the email delivered to website admin at least, even if Reply-To is wrong)
