DNS Email Server not sending mail

I still haven't had any luck fixing the email from server issue. I changed the phpini file to /user/bin/sendmail

I now get this error message after sending an email using the contact us form on Xenforo.

Code:

Swift_TransportException: Email to webmaster@domain.com failed: Unsupported sendmail command flags [/usr/sbin/sendmail]. Must be one of "-bs" or "-t" but can include additional flags. src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/SendmailTransport.php:146

Any help would be appreciated

I have done each step in your link. I reverted the line I uncommented in php.ini. I still get this error:

Code:

}

I am at such a loss as to why this still doesn't work...

That was by bad for not restarting php. I have restarted php. Still no email sent though using the contact us link.

Thanks,

I followed all your steps. Still won't send email through contact us link. I scored 9out10 mail-tester.com site. I thought I remember reading that xenforo send emails out using php something... Any other ideas?

Ok I haven't been able to work on theses issues due to health reason. But I am back at it now. Here are my results. Spam Test Result

I have fixed my the spf record. I don't know whats wrong with the dkim record. I also don't know what is wrong with the mx record as I use google apps for this application which returns the correct mx record but not on this test... Any other helpful pointers will be appreciated.

I just did another test and here are the results: Spam Test Result

It says that I don't have an mx record for my
firegrilled.food-karts.com. Do I need to set that up in order for this to work correctly?

Thanks,
