I recently installed exchange 2010 on my home server, pointed all my dns records to my exchange. i can send emails to my gmail account, my work exchange account, just fine and reply also, but recently i have noticed i have not been receiving to some of my recipients, i have the domain tingateitsolutions.com.au and have send to another .au domain, he got the email, replied, but i never got it. he then replied on his ipad, and it came through. Both the same settings, but i only go the reply from the ipad. i also signed up to cnet but didn't receive the confirmation email. so had to activate manually, got the ticket email from them, and the email that my account had been activated manually.
not sure what the issue is!
any ideas ? if you need any info i am happy to get it to you!
thnaks!
