RainLoop\Exceptions\ClientException::__construct(): Argument #2 ($oPrevious) must be of type ?Throwable, string given

[SergeyMosin]

Describe the bug
Unclear error message when email size (large attachment) exceeds max allowed by the mail server.

Most like the error is here:

snappymail/snappymail/v/0.0.0/app/libraries/RainLoop/Actions/Messages.php

Line 838 in e4316e6

throw new ClientException(Notifications::ClientViewError, 'Message size '. ($iMessageStreamSize * 1.33) . ' bigger then max ' . $oSmtpClient->maxSize());

Possible fix (the second parameter should be null) :

         throw new ClientException(Notifications::ClientViewError, null, 'Message size '. ($iMessageStreamSize * 1.33) . ' bigger then max ' . $oSmtpClient->maxSize());
