Hi, I'm having a problem sending email.
Strange letters are coming out in the middle of words, like C1, A1, A3...

When analyzing, I realized that it does this after a specific amount of characters.

I already converted to utf-8 and iso-8859-1 but without success

What you're seeing is called quoted-printable encoding, and on the whole it should not be necessary on modern mail servers which allow 8-bit character sets in message bodies, and so don't usually need encoding. Issues can be caused by the PHP mail() function adding extra line breaks in unexpected places, and the best way to solve that is to avoid it by using SMTP to localhost instead, which you should be able to do by adding a call to $mail->isSMTP() in your script.

Beyond that I'd need to see your script and the output you get with $mail->SMTPDebug = 2;.

this is the result of $mail->SMTPDebug = 2;

Log Email

this is how the sending of the email is configured

does this problem have anything to do with XAMPP or Apache configuration?

The key mistake I see there is setting the content transfer encoding in a custom header. PHPMailer will set that correctly for you, and by setting yourself it's likely to cause a conflict, resulting in the kind of confusion you're getting. I suggest you delete that line.

sorry what line would be the transfer encoding?

This one specifically:

$mail->addCustomHeader('Content-Transfer-encoding: 8bit \r\n');

I also noticed that all your other custom headers have line breaks in, but they are formatted incorrectly - \r\n will not work in single-quoted strings, and you should not be adding line breaks anyway as it they will either be ignored, fail, or produce corrupt messages, so don't do that. For the purposes of the specific issue you described, I suggest you comment them all out for now, add them back when your issue is resolved.

it worked with these settings, thank you very much!

I removed the line:
$mail->addCustomHeader('Content-Transfer-encoding: 8bit \r\n');

and removed all the \r\n from the header

That's good to hear. Generally speaking, PHPMailer tries to make things easier for you - if you find yourself doing fiddly things like adding line breaks or adding transfer encodings manually, you're probably doing more work than necessary!

@Synchro I'm having the same problem again, but now the issue occurs when I attach a certificate to the email. When I remove the certificate, the problem doesn't happen. Have you seen anything similar with the certificate?

Another detail is that in the variable "$aviso" there is a text. If I remove half of the text, it works, but with the entire text it doesn't work correctly.

This is the remaining part of the code.
Notice the red square, that's where I send the certificate.

Why are you manually setting the encoding to 7-bit when you have 8-bit content? That's not going to work, so I suggest you delete that line and let PHPMailer set the encoding for you.

bcs018 commented Feb 2, 2024

I've already done that, removed the 7bits, set it to 8bits, and left it empty. The issue is that when I don't set the encoding to 7bits, it gives an error of invalid signature.
As mentioned in a previous topic here about signatures, where there was an issue with an invalid signature, the fix was to set the encoding to 7bits.

Apparently the issue lies with the signature itself; when removing the signature $mail->sign(), everything works perfectly.

That's odd. I wonder if the signing process has trouble with UTF-8?

log

@Synchro In this test I performed, the email was sent without a signature, and if you observe in the log, it contains strange characters, yet the email is received normally. However, when the signature is added, these characters are included in the email.

Synchro commented Feb 2, 2024

The "strange characters" are normal quoted-printable encoding, which you can see is the designated encoding in the content-transfer-encoding header. Can you show how it looks with a signature?

@Synchro Do you want me to capture the output of $mail->SMTPDebug = 2; with the signature?

It's happening to me too, I don't know what to do anymore. Have any of you solved the problem?

@Synchro Do you want me to capture the output of $mail->SMTPDebug = 2; with the signature?

Yes. I'm guessing that something is messing up the MIME structure when signing a message, but I need an example of it failing to see what it's doing.

@Synchro I thought it was better to put it as an image because text gets disfigured.

This first one is an example with a signature:
log com ass 1
log com ass 2

This one is without a signature:

log sem ass

@Synchro I managed to find out where the problem was, instead of using $mail->Body to write the message, use $mail->msgHTML().
It worked out perfectly, thank you for your attention.

That's odd, but I'm glad it's working for you! msgHTML() is only a convenience wrapper – if you look at its code you'll see it does some minor rearranging of content to import images, but then it just sets Body and AltBody.

In the images, you can see that the signed one has a content transfer encoding of 8-bit, but the message itself contains quoted-printable-encoded content. The unsigned one has the same content, but the transfer encoding is correct (so you see properly decoded content when you receive the message). That's probably the underlying cause of what you're seeing, but I've not looked into how that can happen.
