Hi, thank you for your fast reply. Activated debug mode and did some testing with test adresses of my own domain. I find it very irritating, that the plugin says all went well, but now, when I check log, I find entries like <i>01-06-2023 18:24:18 – ERROR – 7.7.0 – 18,9 MB/1 GB – [cron] > SMTP Error: The following recipients failed: XXXXXXXXXX: [OR2] Too many mails received from cj0ujf08v within the last 5 minutes (84ab89a7-00a9-11ee-98a2-93d20420dc3f)</i>
This would mean, that all users have to check the log, because they can’t trust the success message in the plugin. But then, why is the log mode optional and not mandatory?
Still have the problem, because of missing “standard log mode” some weeks ago, I do not know, what happened and why some people did not receive my mail. And only way to find out, would be to do a real mailing and hope, that something is written in the newsletter log.
