Hello Guys,

I have VPS on contabo provider. I installed the VestaCP on Debian 9 and web server works perfectly, but not mail server :(

I can't send any mail from my eMail client (MailBird), but I can receive it. However, all works well on RoundCube and MXtoolbox. So, I done telnet test:
<CODE>220 mail.lukasz-developer.com ESMTP Exim 4.89 Sun, 20 Jan 2019 11:39:01 +0100
421 mail.lukasz-developer.com: SMTP command timeout - closing connection</CODE>

I quesed that the problem is causing by my network. I disabled all firewall, but without success. However, I am not sure; maybe my network provider block the 25 port in a deep way.

Any ideas?

Raise a ticket with Contabo... your SMTP ports may be blocked by the provider

I solved the problem. I changed the OS to CentOS 7 + CWP.
