I have an domain account configured with Ipower.com. If I use an email client such as Evolution, the mails arrive as expected. However if I use Outlook 2007 (as everybody in this company) the mails only arrive if the destination belongs to the same domain. That means when the destination is a gmail address, for example, the test email falls into a sort of black hole... (I check the spam folder, and they aren't there)
This is just a simple ipower setup, nothing of Exchange or something like that.
What else can I do to isolate and fix this issue? This is driving me nuts because in other email client with the same exact configuration in the same machine, everything works well and I need to fix the thing in Outlook.
I enabled the Outlook logging feature (*) and the server says everything goes well, but not really.

Are both email clients using port 25? Maybe evolution is configured to use port 25 but has a box checked for "TLS/SSL Enabled" which is causing it to send over 587 (seen this in eudora).
Their documentation asks to use 587 as outgoing. This is a counter intuitive solution because your log shows the email going out fine, but its worth a shot.

The last line is an OK from SMTP server, that means it's done so the issue is not on your end! You should contact the domain provider.
