Sieve scripting

[Lefteris Tsintjelis via dovecot]

I want to monitor a special folder and execute a shell script each time 
I put an email to it. I would like to automate that way the process of 
SPAM reporting (SPAMCop). Is that possible with sieve?

Re: Potfix+Dovecot with dsync replication problem

[Aki Tuomi via dovecot]

Your problem is that you are running service doveadm as vmail, but you
are using real uids. You need to start doveadm server as root to be able
to switch into the correct target user.

dovecot 2.2.36 and wforce

[Tobi via dovecot]

Hi list

I'm trying to setup dovecot 2.2.36 on a Centos6 to communicate with a
wforce daemon on the remote side. wforce is latest released from git
repo. Daemon part is working and I can successfully send queries from
remote systems to wforce via curl

For dovecot I configured in /etc/dovecot/conf.d/95-wforce.conf

> auth_policy_server_url = http://REMOTE_IP:8084/
> auth_policy_hash_nonce = my_random
> auth_policy_server_api_header = Authorization: Basic 
> auth_policy_request_attributes = login=%{requested_username}
pwhash=%{hashed_password} remote=%{rip} device_id=%{client_id} protocol=%s

restarted dovecot without errors, but upon testing via imap I cannot see
just one single tcp paket leaving direction REMOTE_IP on port 8084. It
looks like auth policy in not involved at all.

Thanks for any idea

Doveadm sync, Error: read(remote) failed: EOF, Error: read(remote) failed: EOF

[Marc Roos via dovecot]

In the manual page this command is used for converting a mailbox

doveadm sync -u test mdbox:~/mdbox -x INBOX -x INBOX/*

Yet I am getting this error and the mdbox folder is not created.

dsync-local(test): (version not received)
doveadm(test): Fatal: execvp(mdbox:~/mdbox) failed: No such file or 
directory

[@ dovecot]# doveconf  | grep mail_locat
mail_location = 
mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d
ovecot/%u/index:LAYOUT=maildir++

Users are not having shell access so something like su test -c '' will 
also not work. 

What would be a work-around for this?

Could you provide output of 'doveconf -n'? Also, any auth policy interaction 
should be logged with auth_debug=yes.

Aki

Re: dovecot 2.2.36 and wforce

[Tobi via dovecot]

> Also, any auth policy interaction should be logged with auth_debug=yes

after I enabled that in 10-logging.conf and it did not show any more
loglines I realized that this is a very old box (loads of karma) which
likes to have all its config in /etc/dovecot/dovecot.conf :-)
So after setting the auth policy settings in dovecot.conf it works like
charm :-)

Cheers

LMTP and Sieve with

[Paul Muster via dovecot]

Hi there,

Dovecot's LMTP implementation and Pigeonhole Sieve already do support
the  format. RfC 5233, the Sieve subaddress
extension, also offers .

Could Docecot's LMTP and Pigeonhole be extended to that effect?

Thanks & greetings,

Paul

Frequent Out of Memory for service(config)

[Root Kev via dovecot]

Hello Group,

We have dovecot deployed as solely a Pop3 service that is used by our
applications to pass mail from one application to another internally.  We
have roughly 4 applications that connect to the Pop3 service every 2
seconds, to check for new messages and pop them for processing if they are
present.  Depending on the site, we have between 1024-2048MB of memory set
for default_vsz_limit.  In all systems we see the Out of memory alert
several times a day. We previously did not see this at all when running on
CentOS6, with less memory.

We have tried increasing the memory to the vsz_limit up to 2gb without
success.

We are running on CentOS 7 servers, running dovecot 2.3.6 (7eab80676) (from
the dovecot repo).

Can anyone advise any other settings that could be modified in order to
correct these out of memory issues?

Userdb userdb_mail=, error Mailbox list driver maildir++: maildir_name not supported by this driver

[Marc Roos via dovecot]

I have this default configuration [0], when use the userdb_mail to point 
to the mdbox location, the inbox subfolders show differently in a 
firebird client. So I decided to copy the whole default mail_location 
into the userdb_mail configuration [2]. But then I get errors [3]. 
Should I change the namespace configuration here, how? My default 
namespaces are inbox and 4archives

Are you intentionally mixing mbox and mdbox? You see that [0] has mbox, and [2] 
has mdbox.

Yes, see

It seems to work great but only within the same server. It I copy 
anything from a different server it simply does not work. Is there a way 
around this?
