Using Office 365 with Plesk

[Tinus]

Hi all,

I'm using Office 365 as external mail provider. MX record points to Microsoft mail server. In Plesk, mail support is disabled for the domain. Sending mail from external works. Sending mail from server command line works.

But sending mail from PHP (Wordpress) fails.

What I'm missing? I found http://kb.odin.com/en/418, is there any other kb I need to read?

Thanks
Martin
