Hello Everyone, i´m going to make it quick, ****************************************** Problem #1
We are receiving a lot of errors from the Queue of postfix, and emails are not going out, we are getting this error: host mx2.hotmail.com[65.54.188.72] said: 451 Couldn't open temporary file (in reply to DATA command) We have also seen that we have been marked as a blacklist in this is: http://www.uceprotect.net ********************************* Problem #2 Also, We are getting the same error when we are sending emails inside our network "without sending them through internet" with our outlook, we are getting the error: 451 Couldn't open temporary file when we try to send an Email Configuration Test, I understand the problem with the blacklist, but why is our outlook giving us that error when we send them inside our domain? Thanks a lot in advance.
