Hello,
from time to time I keep getting problems with some emails causing
signal 6. I've already reported those, but it seems not to be easy to
find the cause. From the logs, it seems to occur in sieve implementation.
I've checked the email envelopes tody by accident, probably this part of
my telnet session might help:

The first message causes signal 6, the second does not. Probably the
problem is killed by the two consecutive "NIL"s? I'm not an experienced
administrator, only managing my private computer, so I don't know the
meaning of every envelope field. But might these two "NIL"s cause the abort?
BTW, to download all messages from my IMAP account to my private dovecot
instance I had to delete the first message, since I couldn't download
any other messages from the IMAP folder otherwise.
Kind regards
Peter
