Hi folks,
I did a bit more digging in the coredump and found that the crash
happens when copying a file into any folder that is configured as
"unusre" using the "antispam_unsure" config variable. This was
originally my INBOX, but I just configured some random folder as
"unsure" as well, and the

That's inconclusive: I can copy stuff in and out of my Spam folder just
fine using mutt. I've never seen the crash for my user so far, which
suggests this is specific to
Hey Aki,

I just sent those over in a reply on my original mail. Also note that
dovecot-antispam seems to be involved somehow, as noted in that mail.

at least the antispam plugin is involved in these
imap sessions, and might the the one causing the crash. I'm running the
latest antispam version from Debian (2.0+20170109-1+b2, which also seems
to be the latest upstream).

Hi,

see them in the logs, I haven't had any users complain, so I haven't
looked closely until now. I was originally using an older version fro

I'm using dovecot 2.1.7 (from Debian stable) with sieve. I have default

This is a very old and obsolete version. This problem was fixed
almost two years ago:
Ah, cool. This is what Debian/stable ships, so I'll probably stick to
this version for a while. Good to hear it's already fixed, then I'll
just work around
Hi Stephan,
You asked this one on IRC a while back right?
Yup, that was me.
The copy-on-write scheme I describe above may solve this, as it

Cool! I've just tested this patch on 1.2 (current hg version), and the

now.
Are there any plans to include this in 1.2 still?

Well, fine.. http://hg.dovecot.org/dovecot-1.2/rev/367ce71922bf
Woohoo, thanks :-)
But I don't know when 1.2.14 release will come, if ever.
We'll see. For now I'm just running a patched version, but this saves me
the trouble of recompiling if 1.2.14 every gets released :-)

Hi Frank,
Is it possible to activate home directories auto creation when using

If you're using pam for authentication, you could perhaps use pam_mkhomedir?
This works for any PAM app.

P.S. any idea why rawlog doesn't work ? Where should to log-file be placed ?
Did you see http://wiki.dovecot.org/Debugging/Rawlog ?
It works by checking if dovecot.rawlog/ directory exists in the logged in
user's home directory, and writing the traffic to mmdd-HHMMSS-pid.in and
.out files.

Doh. Seems I skipped a few lines and misunderstood others. The

1) User logs in to imap from 192.168.0.1. What is foo's value?

remote_ip 192.168.0.0/24 {

This one is easy. It should be foo in any case :-)
Why? /24 is more specific than /16, but protocol imap
You are right, and I left out half of my thoughts. I think there should be
only a coarse grained concept of more specific rules - e.g. a protocol
section is more specific than general config, and a local or remote IP
restriction is more specific than a protocol section. I think that the

Hi Eugene,
But really, all this leads is that admin has to detect the dovecot
termination and simply go and restart it manually -- after some bad
thoughts.
During normal operation, on 99% of the hosts, the clock should never need to
leap backwards. So if that ever happens, it seems fine
Hi Scott,
One could always run the mailstore on LVM and then you could snapshot the
mount and then fsck it while still technically in use. It would probably slow
down the filesystem, but it is still live.
Uhm, and then you have a nice and fsck'd snapshot, but your live filesystem

I'm using the virtual plugin for a virtual inbox (with dovecot 1.2, r8980),

If so, I would drop SSL/TLS and sniff the connection, whether or not
Thunderbird checks the mailboxes at all.
If you want to sniff the connection, you can better use the rawlog utility,
which works with TLS as well. See the wiki page Rawlog for more info.

Hi Proskurin,
Seems to it is not possible in near future. It is heavy used production

I think you should still be able to pull this off with rawlog. It relies on
the mail_executable setting, which you should be able to set for some specific
user only using some userdb magic.
Hi all,
Look at the antispam or pipe plugins of Dovecot.
Or write a demon watching with something like inotify and act accordingly.

Normally to disable logins for a user we chmod their mail store to 0
