Re: [Dovecot] Fwd: official dev team position regarding multiple times requested feature (global sieve)

[mailing list subscriber]

sorry folks, please ignore me. my head is is spinning trying to get
hardlinks and default sieve script working at the same time, writing
to dovecot and cyrus at the same time. one is doing the hardlink part
good, and the other the sieve. both fail to get both features right at
the same time. the previous message was intended for the other imap
server :)

The page at http://cyrusimap.web.cmu.edu/mediawiki/index.php/Report_A_Bug
says: "If you are absolutely positive you have discovered a bug[...]".
This might be misleading since this is a feature request and not a
bug.

Leaving the technical details of the proper way to report this I'm
still curios if the developers are actually AWARE of these repeated
requests.

That's another problem with the poor IT guy trying to assemble bricks
from different vendors: when he finally is heard, the answer is "uhm,
the feature you requested fail beyond the scope of my brick. I'm
sorry, I can't do that", even when there is a proposed patch
available!

If you read carefully all my referenced links you'll find one that is
listing other imap servers that support it. From what I've tested, at
least one implementation has done this as a global pre-user execution
of a script (dovecot)

Unfortunately that feature only addresses PROVISIONING of data, which
is quite unuseful since cyrus mail admins do this with the auto-*
uoa.gr patches (that's another pain that devs refused to include for a
long time) - What it lacks is the ability to handle CHANGE (change of
default script, or alter existing user scripts).

[Dovecot] maildir_copy_with_hardlinks on v.2.0.19

[mailing list subscriber]

Hi,

I'm trying to get the so-called "single instance store" (I think cyrus
has got the name for the first time) with dovecot --version = 2.0.19
binary package installed from ubuntu 12.04 lts official repo.

I have checked that "maildir_copy_with_hardlinks" is enabled ("dovecot
-a|grep hard" shows "yes") then I have installed and enabled the lmtp
component of dovecot. The configuration "dovecot -n" is pasted here:
http://paste.lug.ro/131180

Also in the same paste is a strace against dovecot and childrent
showing evidence of the MTA delivering a single copy of the message
via LMTP with multiple RCPT TO: headers.

However when looking in the Maildir, I see the mail break down into
three separate files instead of expected hardlinked files ("stat" and
"ls" shows one single link count, inodes are different)

Given the above data, what (am I | dovecot is) doing wrong?

Please cc me if you need additional input when replying as I'm not
subscribed to the list (I'll watch the thread online only)
Many thanks in advance.

[Dovecot] doveadm quota get -u segmentation fault

[subscriber]

Hello!

I'm trying move to dovecot2 (centos 5.5, dovecot 2.0.8, dovecot
compiled/packaged via edited dovecot2.spec from fedora git).
Almost all fine, I can login via imap/pop3 and work with mail.

I get segfault error with "doveadm quota get -u user"

[Dovecot] xexec and dovecot 1.1

I did not write that module, but tonight I got a bit bored, so I gave it 
a quick try to port it to Dovecot 1.1. The attached patch provides a 
compile fix to make it compile without warnings for dovecot-1.1. I only 
tested whether the module is successfully loaded by Dovecot and not 
whether XEXEC still does what it is supposed to. It does not segfault on 
the xexec command, but that is all I tested. I got a backend command 
error and now it is bed time for me, but there is a good chance that  this
works if you bother to read the wiki page properly ;)  So, consider  this
to be more like an 'It  compiles! Ship it!' kind of fix. But,  anyways, it
should help you to get where you want.

Just apply inside the xexec directory using the usual patch -p1. Let me 
know what you find out.

Regards,

Stephan.


Thank you, Stephan, for your help. Patch applies without any problem and
compilation was successful. According maillog, Dovecot load it without
problems too:

[Dovecot] max connects per host?

I would personally use the operating systems firewall software for this.
Seems redundant that every piece of software accepting connections
should duplicate the functionality of a firewall.

/Johan

Yes. In some cases it could be good choice. But in _general_ it's not.
It's about functionality of a mail server, isn't so? And how your users
will know, what they reached limits and it's not case of broken
connection/firewall/network related problems and so on?

[Dovecot] xexec and dovecot 1.1

[subscriber]

I'll test very interesting plugin xexec. It seems very nice and can be
used in many things. It's compiled perfect with dovecot 1.0, but certanly
not with dovecot 1.1. It's stopped with next error:

In file included from cmd-xexec.c:30:
xexec.h:8: error: expected specifier-qualifier-list before 'array_t'
cmd-xexec.c: In function 'cmd_xexec':
cmd-xexec.c:134: error: 'array_t' undeclared (first use in this function)
cmd-xexec.c:134: error: (Each undeclared identifier is reported only once
cmd-xexec.c:134: error: for each function it appears in.)
cmd-xexec.c:134: error: expected ';' before 'union'


I found, that in dovecot 1.1 has been changed some of functions of array
init and so on. I'm not programmer :(, just a system admin., but first of
all have to check it and trying to resolve by myself.

According examples in ../../lib/array.h I removed array_t and this code is
seems ok:

xexec.h
struct xexec {
ARRAY_DEFINE(setups, struct xexec_setups *);
};

and also here:

cmd-xexec.c
ARRAY_DEFINE(command, char *);


After, errors cames with

cmd-xexec.c: In function 'cmd_xexec':
cmd-xexec.c:144: warning: passing argument 4 of 'client_read_args' from
incompatible
pointer type
cmd-xexec.c:159: warning: assignment from incompatible pointer type
cmd-xexec.c:180: warning: implicit declaration of function 'ARRAY_CREATE'
cmd-xexec.c:180: error: expected expression before 'char'


As I understand, it is because of (from changelog)

Replaced ARRAY_CREATE() macro with [ipt]_array_init() macros. The
macro has no side effects so it might as well be lowercased.

I have look at the array.h, but can't find appropriate function in list of
array_create,i_array_init,p_array_init,t_array_init.

Should I just forget about it, until someone adapts code for dovecot 1.1, or
maybe it no so complex, as looks?


Thank you.
