Hello, I want to use our Exchange server (in the same LAN) for sending emails.
I setup a new Sending Profile and then try to send a test e-mail.
I have captured the SMTP conversation in Wireshark and it seems like the client (the machine running the GoPhish service) closes the connection by sending a QUIT command (see below - IP addresses and hostnames redacted).

This happens 10 times and then stops (perhaps related to the max connection attempts?)
Any ideas appreciated.
Thanks in advance
