Emails that are like a conversation and are exchanged back and forth, with each participant adding their comments above or below existing text is called threading. It lets each participant read the complete conversation as parts are added.
That threading on my email servers was broken without my knowledge. I was responding to friends and customers as I usually do by adding my text and pushing reply.
Customers were telling me they were not hearing back from me, but there was no indication of undelivered email. No bounce, nothing. Most of my send / received email was working just fine.
I had trouble with my email about the first of December and I wrote the post before this one about my issues with POBOX.COM. I was assuming any issues were perhaps left-over from that fiasco.
But the occasional complaints continued. So I had a friend of mine (call him Mike) help me with some email troubleshooting. Mike was a non-customer who was having the problem of not seeing my email replies to him.
It took a while, but what I discovered was that my local email SMTP server was not sending any email that was a threaded or chained email. No error message, no undelivered mail, just not sending it on.
My ISP is named Site 5 and I have ranked on them before in this blog (do a search) Email has been a problem from day one. Not sending a threaded email is a total new-one on me.
I have switched my SMTP server to Amazon Cloud SES (Simple Email Service) and all is working fine with threaded and all email messages.
Site 5 works well enough for most things, but they are very much a disaster with managing email. The certificates on the email server I use at Site 5 are reported to be wrong and not trusted by Microsoft Outlook.
Site 5 also gave me a terrible time last year restoring my SSL certificate after they moved my websites from IXWebhosting. They seem to have no concept how business websites depend on SSL security for business.
To my customers who must think I can’t make a decent reply, I am sorry. From my side it looked like all was well. I was thinking you were just not replying back again.
It’s fixed now. Threads should not be a problem. We will move on from here. ~Dan
