Does anyone have the same problem for that? Please suggest how to solve this problem. Thank you and have a great day.

Hi Chadsel Chen,
Your logs are saying that connections are prematurely lost with other SMTP servers and it seems to make some trouble in queue management.
Maybe there is another problem but :
It could be peering problems with these servers but it can also be a problem with firewall SMTP protocol scanning. Firewall appliances such as Cisco PIX/ASA are closing connection when there are unauthorized commands sent.
Recently we got some problems with SMTP servers sending EHLO command while firewall was only allowing the 'HELO' syntax. The firewall action is to close the TCP connection or not send any response.
If you have such a firewall, try to disable at least temporarily SMTP protocol scanning.
Regards,
pat.
