Seem to have an awful lot of these in my xenforo server error logs.

Code:
#0 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php(344): Swift_Transport_AbstractSmtpTransport->assertResponseCode('', Array)
#1 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/EsmtpTransport.php(305): Swift_Transport_AbstractSmtpTransport->executeCommand('DATA
', Array, Array, false, NULL)
#2 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php(392): Swift_Transport_EsmtpTransport->executeCommand('DATA
', Array, Array)
#3 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php(499): Swift_Transport_AbstractSmtpTransport->doDataCommand(Array)
#4 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php(518): Swift_Transport_AbstractSmtpTransport->doMailTransaction(Object(Swift_Message), 'forum@airportci...', Array, Array)
#5 src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php(206): Swift_Transport_AbstractSmtpTransport->sendTo(Object(Swift_Message), 'forum@airportci...', Array, Array)
#6 src/XF/Mail/Mailer.php(312): Swift_Transport_AbstractSmtpTransport->send(Object(Swift_Message), Array)
#7 src/XF/Mail/Queue.php(148): XF\Mail\Mailer->send(Object(Swift_Message), Object(XF\Mail\SmtpTransport), Array)
#8 src/XF/Job/MailQueue.php(12): XF\Mail\Queue->run(8)
#9 src/XF/Job/Manager.php(260): XF\Job\MailQueue->run(8)
#10 src/XF/Job/Manager.php(202): XF\Job\Manager->runJobInternal(Array, 8)
#11 src/XF/Job/Manager.php(86): XF\Job\Manager->runJobEntry(Array, 8)
#12 job.php(43): XF\Job\Manager->runQueue(false, 8)
#13 {main}

Just wondered if anyone knew what might be causing this?
 
Similar error here. Anyone have a clue what the issue might be?

To confuse things even more, I checked with the user who's email address was listed in the error and he let me know that yes that is his email address and yes he is getting his emails from the forums. So even though something is causing this email error the email is still be delivered to the forum member.
