Hello dear eM Community,
I’m opening this thread because I’ve been having a bug for a few weeks now and I can’t figure out if the problem is with my email client or with the Mailcow instance.
I currently use MailCow with the eM Client for Windows. So far no problems, however I noticed that I sometimes lost some emails (invisible in the list and when searching)
After extensive testing and discussion with the eM Client support (I am a Pro customer) forced to admit that they are also lost but here are my conclusions:
- First of all I use S/MIME certificates to sign all my outgoing emails (this is an important point)
- I use the thread view (or conversation) feature in eM Client to group my emails together.
I have noticed in these conditions that when I start a thread (with one or more people) and reply in that thread, from the 2nd email sent from my Mailcow box and signed with S/MIME, the emails start disappearing randomly … (at each new message in the thread the email disappearing can change…)
But the emails are actually present on the server side (and on the client), because when I disable the Thread View function the emails reappear correctly.
My first reflex was to contact the eM Client support to inform them but during the tests with them I realized that this problem only occurred with MailCow. No problem with a Gmail box and S/MIME signature for example…
So I’m trying in a last hope to post a message here to see if any of you are able to reproduce this problem at least to confort me and push it to the eM Client Support.
Thank you a lot and have a great day
