Question

Can't send emails from my server.

  • Posted October 22, 2014

Hello, I’m on Ubuntu 12.04 X64 on 1GB Ram Droplet also I’ve Zpanel as CP. Some emails are failling to be delivered. I always get same messages for same sent email domains: “Undelivered Mail Returned to Sender” and “Delayed Mail (still being retried)” I made some pastebin for both messages. Here: http://pastebin.com/sv8bdpQg and http://pastebin.com/5AeCFNRj

I don’t know how to fix it.

This would be because your IP address does not have a PTR record assocated with it. This is odd, because the PTR should be the droplets name. I’d recommend that you adjust the PTR in the control panel (if possible), or contact support (if adjustment is not possible) requesting they create a PTR record for you.
