This is a fresh install of SBS 2008 with Exchange 2007. Owa works correctly internally and externally. I can send email from the internal server to external email addresses. I cannot sent external emails and receive them internally to the exchange server. I opened IE on the server and went to canyouseeme.org and tested port 25 with Success.
When I send an email from gmail or yahoo to the email addresses on this exchange server I dont get any bounce back messages, but I am not receiving the emails either.
What do you think could be the reason?
Thanks in advance for your help.
