[horde] Import of mbox failes

[Bastian Klein]

Hi @ all.

I started to migrate a sample mailbox to my new horde installation.
I have a 4 MB mbox file of a folder but cant import it.

System says:

"There was a problem with the file upload: The mailbox file was larger  
than the maximum allowed size (1073741824 bytes)"

First there was a 2 MB php upload limit i ran into. But now i changed  
php to 1 GB Upload Limit.
Horde seems to recognize this new limit but still doest not import my  
4mb mbox file.

message_size_limit = 30720000
mailbox_size_limit = 0
virtual_mailbox_limit = 0

Any ideas?

Thanks in advance,
Bastian
