Gmail Draft message error: decodeMimeStr() Can not decode an empty string

[nssnl]

When looping (foreach) through all the returned id's of searchMailbox('ALL'), the loop breaks when getMailHeader tries to pull a draft gmail message.

Error: decodeMimeStr() Can not decode an empty string!

Makes sense, but how can I ignore draft gmail messages?

First of all: I've added support for parsing drafts with the above referenced commit. This change will be included in the next release.

With this change, you will be able to check each single email, if it's is a draft or not:

$mail = $mailbox->getMail($mailsIds[0]);

if($mail->isDraft) {
        echo "Mail is a draft!\n";
} else {
        echo "Mail is NOT a draft!\n";
}

Regarding your question, how you can ignore draft messages:
It seems like as there was once a search criteria to search for drafts only, but this isn't supported anymore.

In your code, you define your IMAP server and the optional mailbox folder like this:

$mailbox = new PhpImap\Mailbox(
	'{imap.gmail.com:993/imap/ssl}INBOX', // IMAP server and mailbox folder
	'some@gmail.com', // Username for the before configured mailbox
	'*********', // Password for the before configured username
	__DIR__, // Directory, where attachments will be saved (optional)
	'UTF-8' // Server encoding (optional)
);

So in this case, you'll open the mailbox folder INBOX. This folder is by the way the default folder, when you do not specify any.

searchMailbox() would now only search for emails in this folder. Since drafts are usually stored in the DRAFTS folder, you should never see any draft mail id's in this example.

If you're looping through all mailbox folders, you may want to exclude emails from the drafts folder by checking the folder name.

How does your code look like, that you get drafts as well?

Thank you for your extensive response. The commit would solve the issue with the draft e-mails, thank you! However, there appears to be a different but -related- issue as well.

The code I'm using for now is in line with example #4 of the Wiki:

$hoststring = '{imap.gmail.com:993/imap/ssl/novalidate-cert}[Gmail]/All Mail';
$username   = [username]
$password   = [password];
$attachdir  = NULL;
$mailbox = new PhpImap\Mailbox($hoststring, $username, $password, $attachdir);
$mailsIds = $mailbox->searchMailbox('ALL');
if(!$mailsIds) exit('Mailbox is empty');
foreach($mailsIds as $num) {
	echo $num;
	$head = $mailbox->getMailHeader($num);
}

Initially, I tested with the mailbox [Gmail]/All Mail and found out that it was the draft email that caused the error.

After that, I tested the same code with mailbox INBOX, and the script gave the same error. However, in this case I did not check which e-mail caused the error as I assumed it would be a draft e-mail (linked to an e-mail in the inbox). Based on your message I understand draft e-mail would not appear in the Inbox (even if linked to an inbox message).

Therefore I did some research by isolating e-mails in a separate folder (gmail label). I this case, it is indeed not an draft email that causes the error, but an e-mail with no subject and only an image in the body.

decodeMimeStr() Can not decode an empty string!.

The email is printed below. I redacted unrelevant info, but did not remove any lines. Also the Subject is empty.

Message continues with image code. After image code there is nothing

I'm happy to share the original e-mail in a private message if that helps.

I just tested your new commit by manually updating the files, and I don't have the above mentioned errors anymore: so the commit solves the issue with draft emails, but also the other example in my email!

Thanks for your help!

Great. Thanks for testing! :)

Yeah, I've just made sure, that decodeMimeStr() gets a string. Providing nothing doesn't make sense. ;)

As all issues mentioned in this issue have been solved, I'll close this issue. Feel free to add comments, if there is still anything else open. :)
