My vps cant connect to exteal mail servers

Hello,

I've installed an vps with directadmin everthing is working properly but when i try to send an mail it cant connect to an exteal mail server.
Everytime it receives an timeout after an certain time

My log is full with these rows an mail mailqueue is getting filled for every mail i try to send
R=lookuphost T=remote_smtp defer (110): Connection timed out

I've already search for it but the solutions that i found wasnt working.
A couple of things i tried: reboot, disable firewall, recompile exim with custombuild but none worked.

When i use the following tests on my local machine i get an response directly
openssl s_client -starttls smtp -crlf -connect smtp.gmail.com:587
telnet smtp.gmail.com 587

With open ssl i dont see anything till the timeout pops up and with telnet i get 'Trying 2a00:1450:4013:c05::6d...' and then nothing happens

The inteet connection is working on my vps because i can ping to smtp.gmail.com

Danny
