Message Move and Copy doesn't work with subfolders

[tiamatloc]

If your inbox structure has INBOX\Archive or Test\Sub and you try moving or copying an email from INBOX->Archive or TEST->Sub it fails with the following error:

Fatal error: Uncaught Webklex\PHPIMAP\Exceptions\ResponseException: Command failed to process: Causes: - request failed - Empty response Error occurred in /var/www/html/assets/vendor/webklex/php-imap/src/Exceptions/ResponseException.php:53 Stack trace: #0 /var/www/html/assets/vendor/webklex/php-imap/src/Connection/Protocols/Response.php(318): Webklex\PHPIMAP\Exceptions\ResponseException::make() #1 /var/www/html/assets/vendor/webklex/php-imap/src/Connection/Protocols/Response.php(308): Webklex\PHPIMAP\Connection\Protocols\Response->validate() #2 /var/www/html/assets/vendor/webklex/php-imap/src/Client.php(669): Webklex\PHPIMAP\Connection\Protocols\Response->validatedData() #3 /var/www/html/assets/vendor/webklex/php-imap/src/Message.php(1108): Webklex\PHPIMAP\Client->openFolder() #4 /var/www/html/cron.inbox.php(148): Webklex\PHPIMAP\Message->move() #5 /var/www/html/cron.inbox.php(75): processMailbox() #6 {main} thrown in /var/www/html/assets/vendor/webklex/php-imap/src/Exceptions/ResponseException.php on line 53

If you try moving between top-level folders (e.g. INBOX to Test) it works as expected.

Note that you CAN read the folder structure of these subfolders (checked to make sure delimiter \ was correct) AND you can read messages in these subfolders (only tested getting From address and Subject line). It is just moving and copying to them that fails.

Hi @tiamatloc , thanks a lot for your report. I had a similar situation not so long ago - it turned out to be a read only folder (only folders inside the "INBOX" were writable).

If you are sure it's not "read only" but something else, please provide some code or even better a test case in order to replicate the behavior.

Best regards and happy coding,

Hi @Webklex,

It turns out that I'm an idiot! Even though I did use $client->getFolders(false) to dump a folder list and check the delimiter at the time my brain must have transposed / to \ (which is what it was before switching to your IMAP client). Writing up some code for you and dumping the folders before attempting to move showed that / is actually the delimiter and using that allows me to move the emails.

Sorry to waste your time!
