Can't connect to server " Timed Out"

[trojanspike]

Hello,
this is NOT Sentora related, I just wanted some advice and being a active forum I decided to post here.

On my VPS I can't send emails to one server (lusodigital.net 83.96.162.35), I mean, it is just that server that I found at the moment.

Troubleshooting the issue I found it was not related to the email, I can't even ping the server neither the IP.

I contacted lusodigital.net and they told me ping commands are blocked (anyways I can ping from my office computer...), they said it is likely a routing issue and it is not their responsibility.

Anyone has some insight on how to troubleshoot this? I would really like to understand what is wrong.

Here are some testing i've done:

• Ping from my VPS = timeout
  
  
• Ping from other places = 100% OK
  
• Send mail from VPS (sentora-postfix) I receive: (connect to lusodigital.net[83.96.162.35]:25: Connection timed out)
  
  
• Send mail (gmail) works 100% OK
  

Thank you!!!
