Hi there,
I ran the update on my “old NS” today, since then I have not been able to call up any emails.
These were the updates of the last three weeks, since I was on vacation I only made them today.
SOGo reports that there is a linked mailbox.
My email program reports no authentication possible.
My log file reports some things but I cannot assign it:
