XF 2.0 Email send error


New member
Hello, I have a problem, I can not send emails on the web. I'm displaying a error more screenshots, do not you know where the problem might be? If the problem has been solved in the past I apologize, but I did not find a way to solve it.

Email transport method:


[*]Swift_TransportException: Email to thetopcz@northmania.cz failed: Unable to send mail.

Shared host? Contact them to make sure that outbound port 465 is open.
VPS/Dedicated server? Check to make sure that your firewall is allowing outbound connections on port 465.

Be sure that you are using the correct SSL/TLS and the appropriate port settings (your SMTP provider should be able to tell you what to use).
Same here, cant fixe it. After registration some users I have to unlocke manual... I am checking every some days userlist for "unlocked" Users. Thats quite anoying. :cautious:
