I am having issues with phpmail and smtp mail. I have whmcs and ip.board installed on my server and they wont send mail using phpmail or smtp. I also use wordpress which seems to work ok. One WHMCS when using phpmail i get this error Email Sending Failed - Could not instantiate mail function. When using smtp i get this error Email Sending Failed - SMTP Error: The following recipients failed: XXXX@XXXX.com I edited the email the X's aren't part of the error I have tried contacted support many.... MANY times but is worthless. I would like to know if anyone.. ANYONE else has had this issue before i just go back over to cpanel. Im sure this is a simple issue with perhaps installation or something, i just cant get support to even try anything other than say o well. Please anyone that can help with this.
