SMTP error and external connection errors.

[modman]

I moved the site to a new server and since then the emails are not sent, the SMTP connection does not happen.

When I enter the support section I get a message that says there are problems with the connection to the outside.

Yet in the same environment there is a test php file to send emails that works perfectly, there is something in IP.Board....

The only thing that has changed there is your server. You are getting connection timed out, so the issue there is certainly in connecting with your smtp server. You mention you are using a test file. My assumption is you are not actually testing what we are doing. I would need more info on that. All I can tell you for sure at present is exactly what you see on your screenshot

Is there anything in particular I can check?

I can't figure it out and the emails haven't been sent for two days, I don't understand.

Now it gives a different error:

Removing SSL:// from the host and i receive this error:

The problem seems to be using PHPMailer, a technician today managed to update the code and get a custom PHP page working that he was using as a test to send emails via SMTP, this page had the same problem as IP.Board: Authentication error.

According to him there was something wrong with PHPMailer....

Just out of curiosity? Does IP.Board use PHPMailer to send emails via SMTP?
Thanks

We use our own SMTP code to send.

After many attempts I managed to solve the problem, basically a firewall was active that did not allow outgoing connections on the port for SMTPs.

Now 80% of emails arrive at their destination but 20% (in particular those related to the replies in tickets) are rejected by Google for this reason:

550-5.7.1 This message is not RFC 5322 compliant. There are multiple Message-ID headers.

In fact, opening the full content of the email in the error log, two message IDs appear:

Can someone explain to me why?

Nothing strange is set in the email settings, I also tried to use the simple sending in text format, without HTML, but the result does not change.

Thanks
