Hi,
I cannot send an email to mail-tester.com. I have tried everything I know of and ran out of ideas.
To sum it up:-
1. I was able to send emails to mail-tester.com last week without a problem
2. Now, maillog displays (Connection timed out)
3. Port 25 is open - I can send emails to all domains
4. Ping + telnet: no reponse (but they work with other domains, e.g. yahoo, google, etc)
5. traceroute cannot pass the first line (192.168.0.1 (192.168.0.1) 0.058 ms 0.025 ms 0.022 ms)
6. Reset router + restarted Postfix + restarted VPS server: no luck still
7. IP address is not blocked - 100% NORMAL status on all testing sites
8. mail-tester suggests this: Your SMTP or web host is probably blocking your emails
9. But our webhost is not blocking anything (and they couldn't help)
Strangely though, emails to mail-tester.com do not bounce back at all.
Have you come across this issue before? What other step one could take in the way of diagnosing and hopefully resolving the issue? Is there something in SMTP or Postfix configuration that can be causing this?
Would appreciate a response!
