Prestashop doesn't send emails

[DARKF3D3]

I just noticed that my site doesn't send the email.

From backoffice if i send a test email in give this error:

Errore: controlla la tua configurazione

The SMTP connection failed to start [mail.nome-sito.it:25]: fsockopen returned Error Number 13 and Error String 'Permission denied'

 

The email setting are ok, i don't understand why it give this error? Any idea?

I found this post, which suggests that it could be an OS level error. Your host may have blocked port 25, or is not allowing your account to execute the fsockopen.

This error also means that the remote SMTP server requires authentication (username and password), and what it received was wrong.

 

I would suggest double checking the SMTP settings, and also check if the remote SMTP gateway supports SSL or TLS and try using port 587 or 465 instead of 25.
