Postfix can't send mails externally
I installed and configure on Ubuntu 16.04 droplet but it couldn’t send email externally.
I’ve tested this scenarios:
- Send an internal emails, it works.
- send an email from gmail or yahoo mail or other email service, it works too, so I receive the email in the appropriate mailbox.
The unique scenario that doesn’t work is when i try to send to an external email services such as google, yahoo, outlook or other site.
Looking into the Postfix logs I got the some different error messages:
a. Network is unreachable
b. Connetion timeout
Could you please help me? I already opened a ticket for looking into this issue (ports configuration and droplet exceptions) but I didn’t receive any feedback/new about the solution… so I’m considering change my VPS cloud provider.
Could you recommend me any other VPS Could server provider?
Thank you all your help.
