Hi there,

I'm the email administrator for several domains, which each one has their own server in our datacenter, but its one the same subnet (187.18.2.64/26). The problem we are facing: 

- Send email from user@mydomain to @hotmail: my server says its delivered, but it never reach the hotmail user mailbox
- Send email from @hotmail to @mydomain: the email is received like normal
- Reply a previous email sent before from @hotmail, so, its a reply from @mydomain to @hotmail: well received

So, the problem is basically only send a new email from any of my servers to @hotmail, but the more awkward behavior is that we don't receive any error in the sender email.

Please, let me know if I can help with something to solve that problem.
I had an e-mail account with MyDomain.com, I terminated my account with them and set up a g mail account a over a year ago, just found out that when people receive e-mail from me the reply is to the old my domain address? I deleted the new g-mail and opened it again, still the same thing ! What am I doing wrong!  What can I do to correct this!
