Hi,
I have installed Odoo 8 on Windows server 2012. I configured incoming and outgoing mail, both returning 'successful' in connection tests. I have no problem receiving emails (POP and IMAP), but can't send any mails out, and I get no errors. The sent mail shows up in Archive in Messaging. I even created a catchall mailbox in my domain but nothing shows up there either.
I tested sending mail to myself (Administrator), to a user, and to a client, none worked. Is there any settings that I am missing?
