So I subscribed to SMTP2GO doing their buy ten months and get two free and added it as a round robin relay, along with my MailChannels settings in SmarterMail, and after a few days of good delivery, cut over 100% to SMTP2GO. It has just worked! The dashboard is also a lot easier to use than MailChannels. Everything is showing up as it should, not bad for something that costs a fraction of the product I have been using. I'll have to see how this goes for more long term, but so far this is looking really good!
