Mail not sending

Hello

I am having trouble with emails being sent from mycart, no emails at all are going out. I have tried creating orders, creating a new user and the contact form, none of them are going out.

My host is 1and1.com and they do allow sendmail, I have another website that sends out all of its emails through sendmail with no issue.

I have also checked the errors logs and there is nothing in there about email.

Any ideas on where I can check to see what may be happening?

Thanks

Try setting it trough smtp if the mail doesnt work. Also try checking the server error logs maybe there's something there.
