Hi Sam,
I solved all occurences of dupplicate like tag names (privé and prive for example) and the importwizard was able to import my items without further error messages...
...I did however encouter 26 warnings about messages that could not be imported (these are in my opinion also errors). The following problems arised;
- Message skipped, too large d(date/time)
- Message skipped, MIME representation too large d(date/time)
In the log file some more information is logged, it seems that there's a max of 10485760(I guess) bits (roughly 10MB) of what can be imported per message, I checked my server settings and the only place where a limit can be entered is global MTA settings (I currently have about 100MB as a limit).
Any idea what is going on?
