THis has been going on for year and one thing that the EA9 never got right is SMTP. No decent logging to determine what that bucket error means. The Domore BRX has an excellent SMTP log to help determine the problems but you're left guessing with an EA9. Now thankfully I have my own email server. It's an old Merak (now icewarp) system that's as solid as a rock even after years. The EA9 has no problem with the biggies like Google and Microsoft but I can see it connects to my system then just disconnects. Without being able to see a log from the EA9 side to determine why it decided to disconnect, there's little that can be done to troubleshoot the problem. The CM5 did not improve either. Still no log. And exactly the same issue with connecting and disconnecting to my mail system. The Domore BRX works flawlessy. So why can't someone take a look at what the Domore is doing right and duplicate that for the EA9 and CM5?
