SMTP - RustDeskPro

[it-boerner]

I can't enter an SMTP server in the RustDesk Console. I have the feeling that German servers or the servers from German providers are not accepted.

After saving, there is always the error that a timeout has occurred.

Where's your server hosted? Is port 25 open on it?

[it-boerner]

No, port 465 or 587 is used and SSL/TLS must be used.

[dinger1986]

Port 25 was an example, can you telnet or connect from whatever your server is to the Mail server?

You need to answer questions ask as well if you want help!

[it-boerner]

Do the ports in the Linux firewall also have to be open for the connection to the SMTP server?

Could this be the problem?

[dinger1986]

They shouldn't need to be incoming but you need to test from the commandline using telnet or similar. Chances are your VPS provider blocks smtp and you need to ask them to unblock

[it-boerner]

Thanks for the help, I will check accordingly

[dinger1986]

I was going to add smtp setup to the docs today and testing anyways

[rustdesk]

I tested Google smtp and AWS SES.

[dinger1986]

It's most likely the vps provider

[it-boerner]

Yes, it is the VPS provider (Hetzner) and ports 25 and 465 are blocked there by default.

[dinger1986]

Please close. I'll write up for FAQs today anyway

[dinger1986]

I'll check tonight 👍
