VPS not sending indicator alerts from MT4

 

Hi,

Can anyone help to understand why my VPS's not sending emails with indicator alert placed onto MT4? I got 2 different VPS providers and both of them refuse to send email, properly configured in Option>Email settings. I got the same email SMTP settings on my laptop and it works fine. However MT4 loaded on VPS with exactly the same settings failing to send test emails. I have contacted VPS providers and they confirmed all ports for SMTP are open. 

Does anyone could help with this issue?

Thanks
