We have a exchange 2003 mail server with a hanging smtp service about once a week, usually on a sunday or monday. The e-mails in our internet provider's batched smtp queue starts piling up, our mail server terminates all sessions with the provider's batched smtp server.
Everytime when the smtp service on the exchange server doesn't function and when I manually stop and restart the SMTP service I get an error message: Could not start the Simple Mail Transfer Protocol service on the local computer. Error 1053: The service did not respond to the start or control request in a timely fashion.
After a server reboot the sessions are reactivated and the e-mail batch is then picked up again.
There aren't any errors in the eventviewer about this event.
How can we fix this issue?
