Email option Not to use Anonymous Relays

[dlweldon]

Is there a possibility of changing the behavior of Event or the email tool itself to not use anonymous relays?

Our Security team does not want to white list desktops, and a lot of our customers don't use server.  Our server IPs have been whitelisted and a couple of desktops, but that's it. So looking to see if an enhancement can be considered for the Email tool and the Event set up.

Here is what we received from Alteryx Support:

Alteryx sends anonymous email, and there is no way to tie (or spoof) a separate IP address to the email to let the server know where it's coming from, or to make it "non-anonymous." The email tool is a very basic SMTP client that currently does not support SSL or authentication. As such if the SMTP server you are connecting to requires SSL or authentication to relay messages the tool will fail to send the intended message(s). If the server IP hasn't been blocked to send anonymous email, you can test in Designer on the server to see if you receive the same error. If it works on the server, you should be able to send emails from workflow scheduled on gallery. Since the IP of the machine itself is blocked from sending anonymous email, there is nothing we can do on our end to resolve the issue for each individual Alteryx user. IT will have to white-list any IP that wishes to send anonymous email. 

Thanks so much!!
