Hello meregha, I actually gave it up after trying every possible thing I could think of; everything was positive!! When I saw your post, I tried it and it worked. I cannot explain it but it looks like leaving it for a while might resolve the issue.

Really sorry for the delayed response -extraordinary circumstances (: Firewalling? I did disable the firewall without success. The strange thing is that it used to work,; emails were sent to test-mailer.com without a problem. This problem appeared out of the blue. The webhost Support team...

Thank you, mow. I tried both mail-tester.com and a gmail address that works. These are the results. mail-tester.com # tcpdump -v port 25 tcpdump: listening on venet0, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes 04:13:00.417337 IP (tos 0x0, ttl 64, id 5443, offset 0, flags...

Apologies for the late response (health reasons). The service provider insists they haven't blocked us. I believe them and there is no reason for them to do so when we can email all others. We have tried every thing we can think of without success. - disabled firewalld - uninstalled...

Is there a diagnostic utility that would yield the exact cause of "connection timed out", for example: firewall / IPTables / Postfix? In our case it looks like "server-related", our server, not the destination's, because "traceroute" doesn't even pass (192.168.0.1 (192.168.0.1), the rest are...

not even a hint or a thought or a simple direction -:)

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...
