RfcComplianceException: RFC 2822

#3 patch doesn't work with latest alpha5 update.

Thanks @mably for the re-roll.

Just happened to me.

@richard.walker.ardc yeah...but one might consider that to be a configuration error too? @TR could decide if they want the module to support such configurations, especially since in your case it's trivially resolved by selecting MimeMail as the sending class.

I am having this problem using a mix of MIMEMail, SMTP Authentication and Mail System modules. The SMTP module maintainers have looked into this issue for their module here -- https://www.drupal.org/project/smtp/issues/3308653 🐛 SMTP From address meta issue Fixed

In Mail System settings, I am using MIME Mail Mailer as the formatter and SMTP Mailer as the sender. This combination is changing the $mailer->Sender value from an address like this:

email@address.com

To this:

<email@address.com>

And thus causing the mail to not get sent with an "Invalid address (Sender)" error.

#28 describes my problem exactly, and #23 fixes it. I am using MIME Mail to format the email and SMTP Authentication Support to send it, as configured in the Mail System module.

I moved servers recently and the only variable that changed was that I moved from using PHP 7.4.33 as mod_php to using the exact same version as PHP-FPM.

I need patch #23 to be able to send mails to mail addresses @gmail.com .
Without patch #23 the SPF entry in our domain is not recognized by gmail and the mail is rejected from gmail.

So this patch should be commited as soon as possible.

Hi Team,

I tried patch #23 with 8.x-1.0-alpha5, and its working fine for me.

Thanks

I ran into this issue again yesterday and it's a bit sad that this is still a problem with stock mimemail.

If I can summarise the patches/MR we have in this issue:

• I've added a MR that tries to alliaviate the concerns in #6 by removing the extra < and > if we're about to call the core email sending.
• We've got a patch in #23 that simply stops adding the < and > wrapping around the return-path address. This seems to have widespread support and lots of people saying it works etc. However in #6 TR you outlined why you don't like this solution.

@TR it would be good to know what sort of approach you might be up for committing? And then we can push into getting that working properly.

Here's a patch for the merge request mentioned by @steven-jones in #33. It strikes me as the better approach given the comments by @TR in #6. I'll mark it as needs review to get the testbot involved.

Dear all,

Thank you for your efforts. Patch #23 worked for me, #34 did not.

Best regards,
Mariska

The easiest [return-]path forward is to remove the <> even though it's valid.

I wonder how those other contrib module senders would break without the <> or do they expect it?

I don't want to discount the strong plea in #10 #3257799-10: RfcComplianceException: RFC 2822 Return-Path → and explaination in TR in #3257799-6: RfcComplianceException: RFC 2822 Return-Path → and it really should be solved in core and/or Symfony. I encourage all who is reading this to read through TRs comments (a few times).

There seems to be a core issue that might resolve this that I plan to test out a bit and try to push forward here:
🐛 Setting the "Return-Path" header doesn't follow RFC 5321 Needs work

#3257799-23: RfcComplianceException: RFC 2822 Return-Path → is the reroll of #3 and my current favourite for RTBCing, but I will leave it not RTBC because it really needs to be addressed in core

New plan, stop setting the Return-Path header (and other from/sender headers). Let the sender decide that (which will need to decide how to get it on the envelope for sendmail).

I deprecated the MimeMailFormatHelper::mimeMailHeaders() public method (in case someone is using it because it's public API)

Thoughts?

Hiding the patch in #34 because it's a duplicate of the MR3

joelpittet → changed the visibility of the branch 3257799-rfccomplianceexception-rfc-2822-no-return-path to hidden.

joelpittet → changed the visibility of the branch 3257799-rfccomplianceexception-rfc-2822-no-return-path to active.

I shouldn't have removed the headers outright in my previous commit to MR14. Adding them back just no longer passing them through MimeMailFormatHelper::mimeMailHeaders()

Guys, I'm confused about which patch to apply and when this problem will be solved.
I get an error when using the Mime Mail formatter.

Symfony\Component\Mime\Exception\RfcComplianceException: Email "" does not comply with addr-spec of RFC 2822. in Symfony\Component\Mime\Address->__construct() (line 54 of /vendor/symfony/mime/Address.php).

@DD 85 it looks like you are missing an email from that error, so might be a different issue. We are using MR 14

I have tried many ways to successfully send an email using mime mail but ended up commenting out the line code in MimeMailFormatHelper class:

  if (!isset($headers['Return-Path']) || $headers['Return-Path'] == $default_from) {
    // $headers['Return-Path'] = '<' . static::mimeMailAddress($from, TRUE) . '>';
    // @see https://www.drupal.org/files/issues/2024-11-20/3488497-1-fix-error-email-not-comply-RFC-2822.patch
    // @see https://www.drupal.org/project/mimemail/issues/3257799
      }

With this everything works, except another hack that I had to implement in the same file, which allowed MimeMail to properly send out emails with Date heade set.

// Run all string headers through UnstructuredHeader() to convert non-ASCII
// characters to an RFC compliant string.
foreach ($headers as $field_name => $field_body) {
  // Drupal uses Symfony\Component\Mime\Header\Headers class, where not
  // all headers are expected/required to be strings (e.g. 'Date' header
  // is required to be DateTime object). Because of it, skip processing
  // header body if it is not string.
  if (!is_string($field_body)) {
    continue;
  }

  $headers[$field_name] = (new UnstructuredHeader($field_name, $field_body))->getBodyAsString();
}

https://www.drupal.org/project/mimemail/issues/3408278#comment-15358107 🐛 Mimemail runs all http headers through UnstructuredHeader() while it should not Active

I am providing this info here because the issue affects the same file. Maybe it helps someone.

Having the same issue, steps to reproduce:
Create a webform with fields name and email
Add emailhandler
from_name = name from the field
from email = site mail

Submit the form with: “foo, bar en baz”

At the moment I have if fixed in hook_mail_alter, but doesn't feel like a good solution.

/**
 * Implements hook_mail_alter().
 *
 * Add double quotes around name to allow comma.
 */
function hook_mail_alter(&$message) {
  $message['params']['from_name'] = json_encode($message['params']['from_name']);
  $message['headers']['From'] = json_encode($message['headers']['From']);
  $message['headers']['Reply-to'] = json_encode($message['headers']['Reply-to']);
  $message['from'] = json_encode($message['from']);
  $message['reply-to'] = json_encode($message['reply-to']);
}
