No emails going to customers except test mail

[onlinerxD]

Hi, i am using prestashop 1.7.4.4

I've been using smtp set up within this shop but on old domain, 

2 weeks ago, i moved this shop to new hosting and new domain, but within same company krystal.co.uk

Before everything was working fine, 

Now  Email function doesnt work at all except test mail,

I mean customer order confirmation, password recovery, 

 

SMTP configuration is fine, (this is my cpanel Email i mean domain email [email protected])

*also tried with gmail smtp yahoo smtp and outlook smtp same problem 

Mail alerts reinstalled, 

Tried with php mail, but doesnt work, 

I have all mail templates in /mail

Same mail templates are in mailalerts/mail

I spoke with hosting people, I ve been told that no ports are blocked, firewall oki, no blocked ip,  and they can see test mails going through but other mails no,  and I ve been told that must be prestashop faulty

 

 

I did try probably all solution from google, no positive results

 

I forgot mention that i cannot see any errors in logs and also for example when resending order confirmation email i got green message The message was successfully sent to the customer.

Same with password recovery, when i do recover password i also have info 

A confirmation email has been sent to your email address

 

Also when i go to Email settings in 

Advanced Parameters

I can only see emails sent from contact form
