Hi

If you restart your transport service do the mails in the queue leave? Are you routing mail through a smarthost?

Hi Khemarin,

If it is Smarthost, are you able to telnet your smarthost using 25 port number?

Also please check your Send Connector setting.

Just quick update.

it has problem with send connector. I just removed and recreate. it's working.

I tried all my ways to fix the problem. I even removed send connectors, restarted firewall and even restarted the Exchange itself, but nothing helped me.

Finally I disabled Ethernet card and re-enabled it on Exchange, and wowww, it was on the fly.
