"500 line too long" error from Exchange

**dbrewster** · 27 Jul 2006, 02:38 PM

Howdies.

This may be an issue for my web host, but I thought I'd run it by here, too.

We started getting a lot of failures on email messages from ZC, usually on long orders of many items.

When I open the server email log in a code editor, I do see <div class="order-detail-area"> <table class="product-details" ... as a very long line, over 2000 characters.

This isn't a problem for a webmail server like Yahoo, but it's making our local Exchange 2003 server reject these orders.

Is there a way I can control line length generation in ZC email??

The error message is:

Code:

Thanks for your guidance!!! I wonder if this affects anyone else?

More information.

Before I upgraded to 1.3.0.x in late April, HTML multipart email had this header:

Code:

Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

After I upgraded, the HTML multipart email had this header:

Code:

Content-Type: text/html; charset = "iso-8859-1"
Content-Transfer-Encoding: 8bit

It appears that coincides with our problem. I would assume that is not generated by our web host, but occurred with the introduction of

Code:

X-Mailer: PHPMailer [version 1.73] via Zen Cart

Before that, it was

Code:

X-Mailer: Zen Cart Mailer

When I look at the email log (these are sendmail error emails rejected for numerous reasons) in a code editor (using PSPad), the email with "quoted-printable" has nicely formed limited line lengths.

The email with 8bit encoding has ghastly long 2000 character + line lengths for order product detail.

I will check in ZC and see where this might be configurable.

Thanks in advance for any expert guidance!!!!

I went and made this change in includes/classes/class.phpmailer.php:

Code:

  /**
     * Sets the Encoding of the message. Options for this are "8bit",
     * "7bit", "binary", "base64", and "quoted-printable".
     * @var string
     */
  var $Encoding          = "quoted-printable";

Is there any reason I should NOT make this change?

thanks in advance!! It seems to be working so far.
