Dear community,

I have recently installed PassBolt (v5.7.2) (PHP version 8.4.16) on my Hostinger server (Debian VPS) and configured it on SSL under my domain.

I am using MailFence for my email server, I have taken all the parameters from the website to configure it but I have no tentative connections received in it (in MailFence logs). I receive a message “SMTP Timeout” in PassBolt, while using the test emails.

I have opened the port 465 on my server and it is reachable on port 465.

Mails can be sent to Mailfence from the servers also.

Thanks for your help,

Best regards,

Walcure

G’day Walcure.

Port 465 is SMTPS (implicit TLS)
Telnet is connecting in plaintext, so “connected then closed” is normal.

ssl://smtp… + port 465 and don’t enable STARTTLS (tls must be No).

Implicit TLS

And if you get stuck I have a whole thing on rolling TLS certs on my demo repo

Let me know if this sorts you out.
