Email configuration: invalid welcome response

Hello

I trying to test my email send feature so I set up email on local instance. I tried testing with OTB notification "Blog Confirm Subscription".

I don't see emails in my inbox and found an error in monitoring. Also I tried another smtp server with same result.

UnknownException: Email failed to send (To: ***@gmail.com) (Subject: Blog: Name: Subscription Confirmation) Message log: { 15:18:22.586 }---- aspNetEmail 3.7.0.10 [20 июля 2018 г.] -----
