I am the owner of www.techmaster.dk running osCommerce 234 bootstrap. Recently moved from my old server with PHP 5.2.4 to a new with PHP 5.5.9
Everything works fine but i have one problem that is driving me crazy. That is the Domainkey not working when sending mails from my shop. Domainkeys is set in DNS and works fine when sending mails from my normal mail system, also it worked fine with the shop before switching server.
I think the problem is with the PHP 5.5.9 mail() function or PHP configuration in my server. Anyone experienced this ? or having any idea how to fix ?
