I have encountered an odd issue with my contact forms- Recently, I've installed v7.2.1 of DNN on a new domain on my server. I have built in DNN for years, and I have NEVER had any problem setting up my SMTP settings and getting contact forms working.
But since I've installed this quarters new instance of DNN on my new portal, I have been getting an error message when testing contact forms. (even though when I test the SMTP settings it works properly, and the test works successfully).
The SMTP credentials I am using that is giving me this error, is working on hundreds of other websites built DNN (5.x, 6.x, 7.x). It's only been since I've installed v7.2.1 that I have gotten the following message.
Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.
I do not know if this is related to the newest instance of DNN, or just a cooicidence. It could have to do with my hosting provider (3essentaials).
Any tips or suggestions on this would be greatly appreciated.
