when i am sending mail to admin Invalid sender data is coming

Answer 1

The problem comes from your setFrom method. Change $sender to below code or try to print $sender to check if you can get Name and email correctly.

public function execute(){
$post = $this->getRequest()->getPost();

try
{

    $this->_inlineTranslation->suspend();
    $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;

    $sender = [];
    $sender ['email'] = $post['email'];                           
    $sender['name'] = $post['NAME'];

    $sentToEmail = $this->_scopeConfig ->getValue('trans_email/ident_general/email',\Magento\Store\Model\ScopeInterface::SCOPE_STORE);

    $sentToName = $this->_scopeConfig ->getValue('trans_email/ident_general/name',\Magento\Store\Model\ScopeInterface::SCOPE_STORE);


    $transport = $this->_transportBuilder
    ->setTemplateIdentifier('customemail_email_template')
    ->setTemplateOptions(
        [
            'area' => 'frontend',
            'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
        ]
        )
        ->setTemplateVars([
            'name'  => $post['name'],
            'email'  => $post['email']
        ])
        ->setFrom($sender)
        ->addTo($sentToEmail,$sentToName)
        //->addTo('owner@example.com','owner')
        ->getTransport();

        $transport->sendMessage();

        $this->_inlineTranslation->resume();
        $this->messageManager->addSuccess('Email sent successfully');
        $this->_redirect('');

} catch(\Exception $e){
    $this->messageManager->addError($e->getMessage());
    $this->_logLoggerInterface->debug($e->getMessage());
    exit;
}}
