Ldap dict for shared mailboxes

[Kees van Vloten]

Hi everybody,

I am trying to construct a LDAP dict for shared mailboxes.

There is a lot of documentation available but nothing specific to this 
usecase. I could not find anything useful on Google nor in the 
mailinglist archives :-(


The best start point seems to be the doc on shared mailbox dictionaries 
(https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailboxes/#user-shared-mailboxes-shared-mailbox-listing), 
in particular the example for SQL dict. But obviously LDAP is different 
than SQL. The dictionaries page 
(https://doc.dovecot.org/configuration_manual/dict/) has  LDAP example 
but it looks like it does not contain all the bit and pieces I need.


Following the structure of the SQL example, I come to something like this:

map {
  pattern = shared/shared-boxes/user/$to/$from
  base_dn = ou=shared mailboxes,dc=example,dc=com
  filter = (&(objectClass=group)(mail=%{from})

  fields {
    from_user=$from
    to_user=$to
  }
}

The "to_user" / "$to" should be filled with the 'uid' or 'email' of a 
nested group lookup of the 'member' fields of the group.


What are the mechanics to get that done? Does anyone has an example or 
pointer to documentation or is a LDAP dict for shared-mailboxes not 
possible / supported? And in the latter case, suggestions about possible 
alternatives are welcome :-)


FYI. the LDAP implementation I am using is a recent Samba4 ad-dc.

- Kees.

Can you please elaborate a bit how you would like to ‘throttle’ the processes? 
Give it less CPU time?

That you can probably achieve by returning 
service/imap/executable="/usr/bin/nice -n 10 /usr/libexec/dovecot/imap"
from users for the throttled users.

What would be the best way to 'throttle' dovecot/imap processes of specific 
users?

What about fixing the health check passthrough?

Re: dovecot: 2.3.16 -> 2.3.17_1

[Goetz Schultz]

Hi,

I would assume that most people have only a cert signed by one ca? Would 
an appropriate method not be to single that ca-cert out into a singe file?


The mail reception is usually not involving dovecot on a level where 
random CA certs are required?


Thanks and regards

I'm building own packages with poudriere and "pkg info dovecot" says
it's 2.3.17_1

Given the fact that this version is dated 2021-10-28 I'm not sure, if
its part of the problem or the solution.


I'll do a complete reinstallation of the server, there are obviously
more problems. For example: I can ssh to both servers (and i can connect
from them to my server at home) but they refuse to talk to each other.
Same with telnet etc. No idea why, so I'll start over and recheck things.

I just tried on macOS 12.1 beta and getrlimit(RLIMIT_DATA) gives RLIM_INFINITY 
for both current and max (and so does my macOS 10.14 box).

On Monterey, using setrlimit() to reduce 'current' works for large numbers, but 
does return error for low numbers.  On my hardware at least, it starts to 
return error around 419 GB.

Re: [EXT] SOLVED: Re: Dovecot does not start on MacOS 12.01

[Aki Tuomi]

I think this is happening because MacOS no longer supports RLIMIT_DATA. We'll 
try to look into this. default_vsz_limit = 0 seems good enough workaround.

Ok... so for some reason the default_vsz_limit is too low for MacOS.

Can you try

default_vsz_limit = 2G?

We don't recommend setting it to 0.

Do you get exactly same error message with that config or something else?

The "service doveadm { drop_priv_before_exec=yes }" bit should go into
/usr/local/etc/dovecot/conf.d/10-master.conf.
Append the bit I have quoted into that file and then restart dovecot.

What command is it that you are running with doveadm?

The also run the following commands (as root):

sysctl -w kern.sugid_coredump=1
sysctl -w kern.corefile=/var/coredumps/%U.%N.core

mkdir /var/coredumps
chown -R 1777 /var/coredumps

The next time  you get that fatal error, you'll probably find a file in
/var/coredumps/

You can then obtain a backtrace from it:

gdb /usr/local/bin/doveadm /var/coredumps/FILENAME 
bt full 

Present the output, together with that from 'doveconf -n'.

Hi!

This issue is due to a bug in fts-xapian. The plugin does not call 
fts_mail_user_init, causing the crash.

Re: SOLVED: Re: Dovecot does not start on MacOS 12.01

[Aki Tuomi]

Hi!

That solution is bit overly broad way to solve this, I would instead recommend

service log {
  vsz_limit = 0
}

so that only service log is affected.
