prevent mail() email from showing up as phishing in outlook?

[toephu]

i'm in an internal organization sending out reminder emails and reports using PHP.. i have all the right encoding and a internal "from" email address. There is one url included in the email however it is an internal intranet site. Outlook still shows the warning message "this may be a phising message and is potentially unsafe..etc"

of course the user can click that and then add to safe list but I would like by default that the emails are safe that way the users don't mistake it for spam.

i use this to mail (with some other stuff above)

$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";
if (!mail($to,$subject,$message,$headers))
  echo "notification email failed to send";

 

 

any ideas? do i need to talk to my Exchange administrators and get them to add the from email to their safe list and this won't show up as phishing?

Do your headers have "From" set? Is your internal site an IP address?

yea, from is set like this

$headers = "From: Admin Blah <AdminBlah@company.com>\r\n";

and I had the admins create the email alias "AdminBlah" foward to my email.

 

yes the site is an IP addy: http://172.168.0.1/blahsite

 

anyway i will try the suggestions in the link above by radar

i added those:

 $header .= "Reply-To: Some One <someone@mydomain.com>\r\n";     $header .= "Return-Path: Some One <someone@mydomain.com>\r\n";     $header .= "From: Some One <mydomain@myhost.com>\r\n"; 

 

unfortunately it did not work..

outlook still flags it as phishing... oh well

at least it doesn't put in the junk email folder.
