Bulk Mail SMTP

If you are using ReplacePart function, that should not happen because the new message body part replaces the old.

I suspect you are using functions to add new parts instead of replacing the old ones.

I tried to use the ReplacePart function, but the message comes with missing parts, like if I send a personalized link, this part need be id changed for each recipient, I send:
abilityweb.com.br/esppacoalpha/site ...
I receive:
abilityweb.com.br/esppacoalpha/site ...

I using HTML. So:
Before recipients loop:

$message= $this->corpo; $email_message->CreateQuotedPrintableHTMLPart($message,"",$text_part);
$email_message->AddHTMLPart($text_part);

In the loop
Here are many functions to change something for each recipient...
$corpo = str_replace('href="', 'href="'.ENDERECO_SITE.substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'],"/")).'/link.php?mlm_id='.$this->mlm_id.'&nvi_id='.$nvi_id.'&link=', $corpo);
...

$email_message->CreateQuotedPrintableHTMLPart($email_message->WrapText($message),"",$recipient_text_part);
$email_message->ReplacePart($text_part,$recipient_text_part);

So, I don't know what part i'm worng

Well those pages you mentioned are returning not found errors.

Anyway, you are sending HTML messages instead of text messages. HTML should be composed as multipart alternative messages, or else the messages may get filtered.

Anyway, that may not be your problem. I would need to see what is coming.

Thanks so much, I found the answer, is just because I'm using the WrapText activated.
Thanks for everything, it's working now!
