We have a windows server 2000. Sometimes we receive 4.4.7 smtp errors. Last error was when trying to send an email to email@example.com. I noticed something weird is happening:If I ping the mail server from our server it goes to a 188.8.131.52 ip which does not corresponds to colglazier. So it looks like it is redirecting it to another site and therefore I receive the 4.4.7 error and can't send the email. Do you have any idea why this is happenning?
Thanks in advance!
