I have installed exim4, but when send an email this error happens:

T=remote_smtp defer (-53): retry time not reached for any host
T=remote_smtp defer (110): Connection timed out
T=remote_smtp defer (101): Network is unreachable

I tried use telnet to test, and this error happens too:

telnet ANY_IP 25
Trying ANY_IP...
telnet: Unable to connect to remote host: Connection timed out

How i can solve this problem?

Hi @TomTicket

If you have a new account, then you need to create a ticket in Support via the control panel and have them un-block your SMTP.
This is to prevent DigitalOcean being used as a spam service.
