Ok, I changed elogd such that only the first 1000 lines of inline attachments are
displayed, with a note of how many lines are truncated. By clicking on the attachment
name, one can still download the complete attachment. I guess the number of lines do
not have to be configurable, but if someone is not happy with the 1000 lines that could
be added.
