Hello everyone, I used the 1and1 server to build prestashop, all functions are perfect, but the mail system cannot be used, I ca n’t even receive the test mail, but there is no error message,I used PHP's mail () and SMTP are not working.
I contacted the technical staff of 1and1, and they told me that PHP's mail () can be used normally. If I can't use it, it should be a problem of prestashop. Then, regarding the problem that SMTP cannot be used, they told me that prestashop does not meet the RFC standard
Can someone help me?
thank you very much
