Email PHP function or SMTP, to prevent email ending in spamboxes?

[Smile]

Recently a lot of our automatic send email using the PHP function ends up in the spam box of customers. We use the PHP function. 

Using the PHP function we get the spf=pass. But no DKIM is added. Would using the SMTP option be a better solution so DKIM is added possibly preventing the email to end up in spamboxes?

I've always used SMTP as was once told it was the better option .If it's true or not I don't really know ,but don't get any issues with emails

Did change it and DKIM is nicely working... But the name of the sender is now "info" Not very informative.... How could I change that? Before it was the name of the shop domain.
