Good evening, My SMTP server doesn't work correctly with Thunderbird. I can without problems send messages from my j.klesyk@coursflorent.fr account that works with outlook and OWL add-on. But since I've installed THE OWL: gmail and another account have stopped to send mails. I can still RECEIVE without problems mails to all my accounts. But SENDING works only through OWL. I join to this message the image of my SMTP servers. Thank you very much for your help. Sincerely, J. Klesyk
