Receive email problem on new server, old server was no problem

[kingcheetah]

Hi,

 

For a while we sat with our 6 shops on server A. Here we had no problems with sending and receiving emails. Now we moved to another server (server A). Now we can no longer receive emails (with 6 shops). The shops are also working fine on server B.

 

If I send a test email, he indicated that it was sent but no email received. Same problem with contact form.

We tried both with php mail and with smtp but both functions, I receive no mail. We have old server A and when I send a test mail I receive him. Sendmail is already installed on Server B.

 

I looked for solutions on this forum but I see no issue with the same problem as me (or on php and smtp mail problems but this is not my problem) Who can help me?
