Piler 1.3.9 / Sphinx 3.3.1

[BKH-Netz.de - Postfach]

Hello Janos,

on a completely new installation with Piler 1.3.9 / Sphinx 3.3.1 and with no 
imported mails i alway get this error:

ERROR: index 'delta1': reserved field name 'from'.
FATAL: failed to merge index 'delta1' into index 'dailydelta1': failed to open 
/var/piler/sphinx/dailydelta1.sph: No such file or directory

Is this „normal“ because there are no mails in sphinx?

On Sphinx 3.2.1 and lower this error never occured on a completely new 
installation.

Regards
