Since I have zero information on what version of our extension you are using or what version of Magento you are using it is next to impossible to even try to offer help.

You will need to do some debugging, that error message seems to trigger from vendor/zendframework/zend-mail/src/Transport/Sendmail.php line 290

Hello. I have a query. We have installed MagePal SMTP extension and it was working fine, now when we test it by sending a test email it shows the success message and Test Message has been transported. So I had maken other email template and I had tried custom email action. But not receiving the email. At that time success send message is shown in Magento Admin Page. If I had checked gmail, but mail was not come in. I am going to send my custom email. Server setting is follow.

Controller/EmailAction.php

  public function execute()
          {
              $data = $this->getRequest()->getParams(); 
              $this->customerRepository = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Customer\Api\CustomerRepositoryInterface');

              $this->transportBuilder = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\Mail\Template\TransportBuilder');

             $this->scopeConfig = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\App\Config\ScopeConfigInterface');

           $this->storeManager = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Store\Model\StoreManagerInterface');

        $this->inlineTranslation = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\Translate\Inline\StateInterface');    

        if ($data) {
            try {
                //get template by id
                $objectManager = \Magento\Framework\App\ObjectManager::getInstance()->create('Magento\Email\Model\Template');
                $template = $objectManager->load($data['template_id'])->toArray();

                // get order
                $collection = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Sales\Model\ResourceModel\Order\CollectionFactory')->create();
                $collection->getSelect()->where('main_table.entity_id ='.$data['order_id']);
                $order = $collection->load()->toArray()['items'][0];
                //get order_meisai
                $order_meisai = $this->getOrderProductInfo($this->_getProduct($data['order_id']));
                // get sender
                $collection = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\User\Model\ResourceModel\User\CollectionFactory')->create();
                $collection->getSelect()->where('main_table.user_id ='.$data['sender']);
                $user = $collection->load()->toArray()['items'][0];
                // get customer
                $customer = $this->customerRepository->getById($data['customer_id']);
                $templateParams = 
                    [
                        'customer_name' => $data['customer_name'],
                        'order_num' => $order['increment_id'],
                        'order_meisai' => $order_meisai,
                    ];

                $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
                $this->inlineTranslation->suspend();
                $transport = $this->transportBuilder
                    ->setTemplateIdentifier(
                        $template['orig_template_code']
                    )
                    ->setTemplateOptions(
                        [
                            'area' => \Magento\Framework\App\Area::AREA_ADMINHTML, 
                            'store' => $this->storeManager->getStore()->getId(),
                        ])
                    ->setTemplateVars($templateParams)
                    ->setFrom(
                        [
                            'name' => $user['username'], 
                            'email' => $user['email']
                        ])
                    ->addTo($customer->getEmail())
                    ->getTransport();
                $transport->sendMessage();
                $this->inlineTranslation->resume();
                $this->messageManager->addSuccess(__('Success send mail.'));
            } catch (\Exception $e) {
                $this->messageManager->addException($e, __('We can\'t send mail now.'));
                $this->_redirect('**************', ['order_id' => $data['order_id']]);
                return;
            }
        }
        $this->_redirect('*************', ['order_id' => $data['order_id']]);
    }

If I have run above code, then Success send mail message is shown but if I check gmail, the mail hasn't come in. Magento version is 2.4.5 and MagePal SMTP extension version is v2.9.0 .

Can you please advise on what can be the issue?
