@Parallels, is it possible to tell us how the /etc/xinetd.d/ files are written to?
(smtp_psa / smtps_psa / submission_psa)I know they can be disabled via Plesk, which just renames them to *.psa (files containing . are not read by xinetd), but it seems that on some servers, no matter what I do, the changes are not written to file..
