--- Comment #16 from Martin Steigerwald <Martin at Lichtvoll.de> ---
I found a grave mistake in one of my crm114 spam filter rules, which may
explain these one-byte-sized files. I did some testing and it seems it doesn´t
cause that harm, but well, maybe it still does:
It may have been this grave misconfiguration causing all the havoc. If so,
please accept my apology!
I will take time to compare my crm114 rules with Sinclair, and with my old one
and think of safe ways to test with new filter rules.

I tried just this misconfigured filter rule a ton of time with Ctrl-J and
triggering via filter actions menu on two test mails. These are still there.
I thought they would be gone. Maybe Akonadi doesn´t accept the pipe result, if
the command returns an error code?
I don´t even see the rm to be called, but may be to quick to notice.
While thats no prove that the rule did not cause any havoc, I have an idea on
how to test crm114 filter rules for one-byte sized files (with crm 114 rules
enabled) safely:
1) create a pop3 test account
2) stuff a lots of mails to this mail account via a for loop and mail command.
3) retrieve mails only from that test account.
I think I will try this way.
I found another mistake with the mark as good rule: It should not be called on
manual filtering, only by being called from filter action menu or icon.
While this should not cause one-byte sized files, it might have contributed to
several filters being called quickly one after another and possible race
conditions relating that.
