blank email (error 500 in horde) with big attachments

[Xavier Brochard]

Hello

Using Kolab 2.2.2, with Horde.

I recently got problems with some emails. It looks like that when total 
attachments are too big (more than 6MB), imp can't display the email (error 
500). Trying to forward the email, ip let me send it, but then I got the 
same 500 error as before.

I've found nothing in the logs. Except with imapd.log: normal email display 
something in the log while problematic ones display nothing.

Any idea?

regards
