Dear Customers,
Due to recent security policy changes, outbound SMTP traffic over port 25 may be blocked on your server.
If your email service has stopped working over port 25, please complete the following steps:
- Configure a valid PTR (Reverse DNS) record for your server's IP address in your client area.
- Verify that your server is properly configured according to our Server Configuration Guidelines to Avoid Spam and Blacklists
- Once the PTR record has been configured, open a support ticket requesting that outbound port 25 be unblocked.
Our technical team will verify the PTR record and remove the port 25 restriction as soon as the verification is complete.
