Emails not working despite using the correct config

Hey, so i use poste.io on a dedicated server to host my email, all ports work well, but passbolt wont connect to the SMTP server, but when i try to send a test email after checking multiple times that the password and username were correct, passbolt says this in the log :
“stream_socket_client(): Unable to connect to tcp://-----:465 (Connection timed out)”
(domain name redacted)
i dont think im missing anything since ive already tried with port 587, and i am using poste’s connection manual. Sorry if the answer is simple but i cant connect from anywhere else without smtp working.



Hello @Alexvarl,
It looks like you are trying to use smtp with TLS enabled, I believe you are using a self-signed certificate on the email server? If so, did you take a look at our documentation
?
