To preface, I’m using the Crossbox mail client hosted by MXroute. I was directed to Dovecot support when I made my inquiry to the former’s developers.
Apparently, when you write an email subject that is verbatim to another, previously sent email, the two become linked in a conversation thread.
I could have an email from 1996 titled “Groceries” and if I make one today titled “Groceries” my inbox would have them connected as one long thread. I’m getting email threads in the 100s because of this.
Crossbox people have told me it’s not something they have control over. They mentioned it being a Dovecot problem. Has anyone encountered this?
It would be tremendously inconvenient to ensure that every email I ever send from now on has a unique subject so to as not have them threaded together. Let me be clear, email threading and conversation views are extremely useful. I just want them to be…relevant to the chain of emails that are being looked at.
Is there a way to group threads by unique header information? It is becoming borderline unusable to sift through invoices.
