Test Mail (PHP default) not sending, errors

[Grammy]

No one's getting any email, including me.  Trying to troubleshoot it this morning, and the mail type is PHP default. I don't have any of the SMTP fields filled in.  I thought I wasn't meant to, using PHP default?  The webmaster email address is connected to the domain hosting the forum (which is the only thing on that domain, root folder).  I see that the test mail is trying to send to my personal email address.  I had thought it would try to send a test mail to the webmaster email address.  Anyway, that failed with these errors:  1 general "unable to send mail" and 2 undefined:  Undefined index: message and Undefined index: subject

If you can spot the issue, I would sure appreciate some help.   

The block of code in Sources/ManageMail.php is:

Code Select Expand

// Send to the current user, no options.
$to = $user_info['email'];
$subject = $smcFunc['htmlspecialchars']($_POST['subject']);
$message = $smcFunc['htmlspecialchars']($_POST['message']);

$result = sendmail($to, $subject, $message, null, null, false, 0);
redirectexit($context['base_url'] . ';result=' . ($result ? 'success' : 'failure'));
}
All of my mods (not many, at that) are all hooks only, except for one which only modified ProfileModify.php and Profile.template.php.  None of the files in the backtrace have been edited.

Most common mail issues can be resolved by actually using SMTP. The PHP default is generally a bad idea, but it's default because it usually somewhat works without you having to set it up separately.

Undefined index: message and Undefined index: subject might indicate a larger problem though, I'd guess that means you were trying to send an email with no content.

Oh, I hope it's as simple as changing that.  I'll do that and report back.  Thank you!

@Aleksi "Lex" Kilpinen      All that, and all that was needed was making that switch, wow!  Thanks so much!
