Pleks panel wordpress 587 port sorunu

port 465 yapıp dene

o da sorunlu hocam sadece 25 çalışıyor

TLS'yi SSL yapıp port 465 yap.

Pleks panelde webmail ve mail ssllerinde sıkıntı yok görünüyor fakat wordpress te 587 portu ile test maili göndermeye çalıştığımda şöyle bir hata alıyorum ( kullandığım plugin ; WP MAİL SMTP ) yardımcı olabilirseniz çok sevinirim. Plekste ücretsiz Lets Encrypt ssl kurulu ve 587 port ayarı mail ayarlarından açık durumda bir sıkıntı yok.
