[horde] Unable to attach files in Whups

Hi, Jan.

Fortunately, I was able to fix it. In some tests trying to attach files
of a few kilobytes, I noticed the files was uploaded without problems.
But with slightly bigger files that those used in these tests (although
always below "post_max_size"), the files were not attached.

Then I tried modifying also upload_max_filesize.
Then I've also configured post_max_size to the same size.

post_max_size = 20M        ; Default (on Debian): 8M
upload_max_filesize = 20M  ; Default (on Debian): 2M


Thank you to all for your replies.
