My guess is that port 25 outgoing is blocked, either at your own server or network, or at that of your ISP. Many ISPs block port 25 for home users; if you're on a business line or inside a data center this doesn't apply of course.

You can test from your server with telnet if you can make a connection e.g.

# telnet alt1.gmail-smtp-in.l.google.com 25
Trying 74.125.25.26...
Connected to alt1.gmail-smtp-in.l.google.com.
Escape character is '^]'.
220 mx.google.com ESMTP iu4si3960824pbc.430 - gsmtp

Or try Microsoft if it's gmail that you cannot reach;

telnet mx1.hotmail.com 25
Trying 65.54.188.110...
Connected to mx1.hotmail.com.
Escape character is '^]'.

Another thing you can do is a simple ping to be sure it's just the port 25 and not an network issue

ping alt1.gmail-smtp-in.l.google.com

I have seen this happen with CSF Firewall , it doesnt matter if you open port 25 in CSF in still blocks because when you use pre defined profiles from CSF and use the highprotection profile it only allows some programs only to use port 25
Please disable for test CSF and look if it helps
 
Hello all,

I am sorry to open an old thread but my problem is exact same.
The OP never told his solution.

I have disabled the firewall using command csf -x

I tired the commands "Arieh" advised but still I get this error (only ping works).

Code:

What can be the problem...? If firewall is disabled what else can block port 110 or 25 ?

Please advise.
 
Perhaps your provider/DC is blocking port 25 because of spam reasons? You could check with them to make sure it is actually something on your server and not your network.

# telnet alt1.gmail-smtp-in.l.google.com 25
Trying 74.125.68.26...

This is how it normal works.

Thanks you were right. The hosting company had it blocked.
