I raised memory_limit to 800M and now it works fine. I lowered the
post_max_size and upload_max_filesize to 20M. It still works fine.
Thanks for your help!
I did forward the 10MB attachment and I was wondering that this takes
about 120 seconds. But my max_execution_time and max_input_time are both
'60'. Strange that it works. To be sure I raised the times to 200 seconds...
Another point I see is that the forwarded message has a size (in Horde)
of 24023 KB. The first message had a size of 14035 kB. Any idea what is
When I download the forwarded attachement the file has a size of
10485612 bytes. The original was 10485760 bytes. The first attachement
(not forwarded in Horde) was still the correct size after downloading.
