No, this is worrying me. It happens to all users. logging in :
[root at imap ~]# cyrus mupdatetest mupdate

S: A01 OK "Authenticated"
Authenticated.
Security strength factor: 56
A1 FIND "user.piessens.Personal"
A1 MAILBOX {22+}
user.piessens.Personal {28+}
mailserv.icsense.com!default {19+}
piessens	lrswipcda
A1 OK "Search completed"
A3 FIND "user.piessens.Personal.Test3"
A3 MAILBOX {28+}
user.piessens.Personal.Test3 {27+}
imapfe1.icsense.com!default {19+}
piessens	lrswipcda
A3 OK "Search completed"

This was due to my mail client trying to autocorrect the spelling. This is not real in my set-up

In a standard murder this option should ONLY be set on backends. DO NOT SET on frontends or things won’t work properly.

It looks like this was the root cause. i need to test this further, but omitting these settings seems to have fixed the issue
A2 FIND "user.piessens.Personal.Test6"
A2 MAILBOX {28+}
user.piessens.Personal.Test6 {28+}
mailserv.icsense.com!default {19+}
piessens	lrswipcda
A2 OK "Search completed"

Thanks a lot for the fast response.
