Doesn't send email at all after moving to new server

[KasperFP]

Hi all,

After I moved our shop (www.nordicnature.dk) to another server (from a Windows based to a Linux based server) I've had several problems. I've solved the most of them, but the last problem is one I really can't figure out how to solve.

The shop doesn't send emails anymore. Not when a new order is placed, not when I send a customer a message, not ever. :-(

I've turned on display_errors, but it never displays an error. It just seems like everything's working, except it's not.

I think I've tried all possible solutions I've found here on the forums, and also the one about changing the Swift files, but nothing helps - nada. If I create a small test file with a default PHPMail script, it works just fine, so I'm guessing it's the classes in prestashop which is wrong (all of a sudden).

Can anyone tell me what to look for? Any ideas is appreciated, because I'm all out of them.

EDIT: Seems like it sends mails just fine, it's the MailAlert module there's something wrong with.. hmm.. I'll check it our
