Hello,
I got problem with spamfilters in MS mail services. People doesn't receive any of my emails from MYDOMAIN.COM.
Only when someone add [email protected] to contacts or to whitelist he'll get an email.
This is my email header:

Hello JMikita,
It is not clear whether you use Outlook or not. It looks like the issue is related to MS services (not only Outlook). That's why I'd recommend asking such questions on the
Outlook IT Pro Discussions  or
Community forums instead. The current forum is for Outlook developers.
I have found a forum thread which describes a similar issue -
Internal Mail going to junk folder. There are various reasons why emails are treated as a spam. The
Why Is My Email Going to The Spam Folder? How To Improve Email Delivery article describes common rules for reducing the chance of email being filtered.
Actually, the problem may depend on Outlook itself too. Outlook performs its own evaluation and determine whether to move or not the incoming email to the Junk Email folder. Note, you can edit the settings on your own. Please see the "Junk " drop
down menu located on the Home tab, it contains the "Junk E-mail option" menu item:
The process of filtering Outlook e-mails is described in the
Description of the improvements and the additions to the Outlook 2003 Junk E-Mail Filter features after you apply Office 2003 SP1 . An old version of Outlook is described, but general rules remain the same.
Also please take a look at the
Understanding Anti-Spam and Antivirus Functionality and
IMF and the Junk E-mail folder in Outlook articles.
