Since downgrading of postfix fixed that issue, from my point of view,
the culprit is at least triggered by a change in postfix. The actual
bug might me somewhere else, e.g. in procmail, yes.

Unless postfix calls procmail with a different user in 3.1.9 and
3.1.12, we IMHO definitely can say that it's not a "no write
permission" issue.
Since mails to other mailboxes in the same directory were delivered,
we can clearly say that "Nonexistent subdirectory" is not the cause
either.
Regarding "disk full": I just checked the monitoring and mount points:
* Both, /var/mail and /home/abe/Mail are on the root partition (it's a
VM) and according to my monitoring, the root partition was around
65% full on 29th of April when I reported this. See the attached
screenshot.
* AFAIK procmail just appends new mails to an mbox-format mail folder,
so the size of the folder should actually not matter, just the size
of the appended mail.
Anyway, quite a lot might have happenend since I reported the issue
and the RRD-based monitoring logs from back then are not that fine
granulate anymore, so that I will try to upgrade again and see if the
issue arrises again. In that case, I happily offer more precise
debugging information than I still have from end of April.
Regards, Axel
