Welcome, confirmation, and some notification emails are sent with the internal PHP mail function to prevent too many connections to the server. Please make sure that the PHP mail() function works. The following script, copied to a php file and browsed to, might be used as a test.
<?php// config$domain = "example.com";$toaddr = "you@NOTexample.com";// end config$fromaddr = "mytest@$domain";$returnpath = "bounceme@$domain";// codeecho date("l, F jS g:ia T");echo "<br>testing mail() function..<br>sending mail.. ";if(mail($toaddr,'mailtest','mailtest',"From: \"Mytest\" <$fromaddr>\nReturn-path: <$returnpath>")) echo "mail seems to be sent ok<br>"; else "mail NOT sent ok!?<br>";?>
If the function is not working you will need to have your system administrator configure it.
Regards,
DW
