Ok so I got back a reply.
In his first email he stated that he was very aware of this issue as he had to deal with it for several companies that had older large printers that sent out alert emails. He said that he used Gmail for a time and that worked but then they made some changes and it no longer works. He said in some secure location cases he just set up email servers at the locations just to handle the problem and at others he spent time searching for email server systems on the web that are free and do not use SSL for mail. He said he located a couple but that he cannot share the info as this might compromise systems that he already has running. I guess he assumes that sharing the info on the web might send a bunch of new people onto these servers and they might shut them down.
He then told me to give him a couple of hours and he would see if he could find something that could be shared. I got a reply back in an hour and he said he tested this out several times and it works. So here is the solution he came up with, the only limitation is that you can only do 1000 emails a month on the free plan
Go To:
https://www.smtp2go.com
Sign up for the free account using your regular email address as that is the one they will send you the login info to. This should also be the email account you want the alerts to come to. Once signed up check your inbox for the confirmation email and follow the steps.
If you get a message about enter a domain, just ignore it. He says it works fine without that info.
You will get a password for the account and an email smtp server address of mail.smtp2go.com using port 2525. You can use port 25 but he does not recommend it as he says that one is spammed to death. I did some checking and the reefkeeper does allow port 2525 so you should be fine.
The emails from the controller will be sent to the email address you signed up with.
So if you used
[email protected] that is where the alerts will be sent.
Please let me know how this worked out for you so I can let him know.
Good Luck
