Hi, i have a big email... i was sending a lot of emails to my registered users...and now my 'activation emails to registration' are now in SPAM folder... i need to fix that and quickly but i have no idea how...
I tried to add some headers but id didnt help and now i have:
$headers = array();
$headers[] = "MIME-Version: 1.0";
$headers[] = "Content-Type: text/plain;";
$headers[] = "From: domainname.com <email@domain.com>";
$headers[] = "Reply-To:
email@otherdomain.sk <email@otherdomain>\r\n";
What should i do to fix that? I googled a lot but i didnt find nothing usefull and i tried a lot ot things.

If someone would help me i would be incredible thankfull.
