Send mails from a Zoho mailaccount not in map Send

One of my mailaccounts is a Zoho mail-account and I have entered all settings in eM to send and receive mails with that account. All settings are correct. This is what happens when I send a mail:

  • after sending the map Send is visible in the map list (icon = paper plane)
  • eM is downloading all send emails (I can see the counter)
  • the list van send emails is visible in right window
  • after downloading all the send mails the map Send disappears
  • all send emails are only visible in an archived map Send (icon = file folder)

Mails are send correct. I am convinced that it is a eM issue:

  • a C-Panel mailaccount: no problem
  • the Zoho account in Apple Mail: no problem

I have compared all settings with my other mailacocunts: everything is the same.

Why is the Zoho account not shown in the same way as all my other mail-accounts?

How about this emclient? Not important enough?
