So I have my own mailserver and everything works as it should. I have my mailaccounts set up, can send and receive mails with outlook or any other email program and I was able to send mails through wordpress and WP Mail. Yesterday I saw that sending mails stopped 1 month ago, even though I didn’t temper with any settings. I tried re-establishing the connection and checked the settings but I can not find anything suspicious. When sending the testmail I just receive the message that the Mail couldn’t be sent because the smtp-server refused the connection (111).
So it worked 1 month ago and stopped.. I have setup SSL (465) and TLS (587) for my server and do not see anything regarding erros in my mail.log. Anybody can help?
I tried reading through the phpmailer troubleshoot guide.. but the error (111) was not listed.
Anyone has an idea on how to solve this?
