Subject encoding is sometime not what's expected

[Naghal]

Describe the bug Sometimes, the subject is not what expected, As an example, I have an email in gmail web browser with subject Maj Vidéotron. When calling $message->getSubject(), I am getting the subject: MAJ =?utf-8?b?Vmlkw6lvdHJvbg==?=. It is the same subject no matter what decoder option is set in the decode.message.subject config. (utf-8, iconv and mimeheader)

To Reproduce Steps to reproduce the behavior: Connect to a mailbox then:

 $this->client->connect();
 $folder = $this->client->getFolder('INBOX');
$unseenMessages = $folder->query()->unseen()->get();

foreach($unseenEmails as $email) {
    dd($email->getSubject())
}

Expected behavior The subject returned by getSubject() should be Maj Vidéotron.

Screenshots raw subject header:

Desktop / Server (please complete the following information):

• OS: Ubuntu 20
  • PHP: 8.0.6
• laravel-imap 2.4.0
• php-imap 2.6.0

Hi @Naghal , many thanks for your report.

Please update your webklex/php-imap dependency to the latest release (>2.7.0). This will hopefully solve the problem. If not, please head over to the webklex/php-imap repository and create a new issue.

Best regards,
