PROBLEMS SENDING MAIL TO: Mailer Error: The following From a

[Michael L]

When a new user tries to register or if the admin clicks 'Reset Password' the email does not go out, and the following message is displayed:

PROBLEMS SENDING MAIL TO:
Mailer Error: The following From address failed: <here it showed the $g_return_path_email value>

I do not see this particular phpMailer error message reported in many places on the web.

I'm running XP
Apache/2.0.52
PHP/4.3.10

$g_phpMailer_method = 2;
$g_smtp_host = '...a valud host ... ';
$g_smtp_username = '... a valid user on the host ... ';
$g_smtp_password = '... a valid password for the user .. ';

I tried with and without this line
$g_check_mx_record = OFF;

Any help much appreciated, thanks!

Let me add that I am behind a router. I don't know if that is related to this problem or not.

Did you try setting the return path email to an empty string?

Setting the return path email to an empty string results in the same error, except that the email address reverts to the the $g_from_email value instead of the $g_return_path_email

Mailer Error: The following From address failed: <<$g_from_email>>

If I set $g_from_email blank, the message shows no email address there:
