not receiving confirmation or autoresponder emails

I’m no longer receiving confirmation or autoresponder emails to any of the addresses I have in email settings. I thought it was a problem with the fact that it was a gmail account, but I don’t receive to any of my email accounts, such as [email protected]. And I have set up SMTP according to my hosts instructions as well.

I renewed my support license and submitted a ticket but haven’t heard any reply. It’s been almost a week now. I feel like that was $25 misspent. I really need to get this working again for my client. Please help.
