Hi Janos, we've a strange situation here, after import all user's email via imap, the sph_index table is not populated and so the search doesn't show results. I've to stop cron jobs and manually rerun a reindex -a to see results of search. After the reindex command I can see results for a search but all the email with attachments don't show attach in the preview, btw if I download the eml the attachments are there.
1.2.0-master build 919 Sphinx 2.2.10 thanks, Cristiano
