Mass Email says it's sending out, but no emails recieved?

[^SuiCyde^]

at first i thought it was an issue with the server, because through cpanel when trying to access webmail, we got an error saying localhost could not connect.......however we submitted a ticket to cpanel and had that issue fixed, and still it says that we are sending out the emails, but none of the members get an email from us, not even me (already checked all spam folders, even set up a new member account with fresh email to see if it was an issue with my email)

both my site and another, hiphopnetwork and globalemcee have this issue

any suggestions would be greatly appreciated.....

once again, it says all emails have been sent successfully but no emails recieved
