already made this attempt, most always get the same reasons.
Hello Mario,
My name is Michael and I work with the Windows Live Hotmail Sender
Support Team.
The messages from your IP's (xxxxxxxxxxxxxxxx/26) are being filtered by
Windows Live Hotmail as the majority of email sent by your IP space has
been judged to be spam by our internal filtering systems. One possible
explanation for this is the automatic forwarding of unfiltered inbound
messages, including spam messages, to Windows Live Hotmail/MSN
addresses.
Please confirm that your emails comply with Windows Live Hotmail's
technical standards. This information can be found at
http://postmaster.live.com/Guidelines.aspx<http://postmaster.live.com/Guidelines.aspx>=20
For more detailed information about best sending practices to Windows
Live Hotmail users, please review the following white paper:
