Emails not being sent out although vB says they went

[محروم.كوم]

Go Daddy migrated me to a new server early Saturday morning and ever since then* my activation emails and "Send email" from the admincp are not working. I went to Maintenance > Diagnostics > Email and did a test and it said that everything went fine.

What could have changed and how might I be able to fix it? I am using the default "internal PHP mail() funcion" in the admincp. Also* I am running 3.8.4 PL1 which was installed after the problem started but did not resolve the issue. I have not installed and hacks or add-ons since the problem started. Everything was fine. If I must say something to Go Daddy* what should I be asking them to check?


Meanwhile* I had to turn off the email activation feature* which I do not like to do. __DEFINE_LIKE_SHARE__
