imap ---- LIST "" * The returned mailbox does not display quotes
by lty 21 Mar '19

21 Mar '19

dovecot version v2.2.29 v2.2.36 v2.3.5 LIST "" * The returned mailbox does not display quotes dovecot version v2.1.17 LIST "" * The returned mailbox shows quotation marks Why is the quotation mark removed in the new version? Is there any configuration option in the new version to add quotes? Because I see a lot of big public mailboxes with quotation marks.

Dovecot crashing when attempting to search in virtual folder with fts_squat activated
by benjamin＠godbersen.info 20 Mar '19

20 Mar '19

Hi everyone, I am running into a problem when trying to use fts_squat in a virtual folder. Without fts_squat plugin the search (from, subject...) works in all folders. With activated fts the search on the inbox folders works expectedly well but any attempt to search anything in any virtual folder leads to the following error. Similarly when attempting "doveadm fts lookup". I also noticed that no search index for the virtual folders gets build - is this expected behaviour?

Dovecot Wiki: Please disable edit on double click
by Michael Goth 20 Mar '19

Hi Aki, could you maybe disable the 'edit on doubleclick' feature on wiki2.dovecot.org? Everytime I try to select a word by double clicking on it, I end up in editing mode. It's just a minor thing, but maybe I'm not the only one who's annoyed by this ;) Thanks! Michael

Checkpassword.
by Niamh Holding 20 Mar '19

20 Mar '19

Hello, I've run into the issue detailed at https://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security Understandably I don't have the skills to modify checkpassword so if I do the suggested will it work? If you can't change the script, you can make Dovecot's checkpassword-reply binary setuid or setgid (e.g. chgrp dovecot /usr/libexec/dovecot/checkpassword-reply; chmod g+s /usr/libexec/dovecot/checkpassword-reply) -- Best regards, Niamh mailto:niamh@fullbore.co.uk

4sec latency when using director
by Erik de Waard 19 Mar '19

19 Mar '19

Hi, I've been running dovecot for many years, but now i've hit a strange problem. when retrieving imap there is sometimes in 1 of 4 imap requests a 4sec latency. * notes: - connected directly to the backends this latency disappears - removing a director from the loadbalancer(lvs) so i'm the only connected to the director this latency disappears too I would appreciate some feedback of where to look because i tried various options. (client_limit,process_limit) perhaps its just as simple as to add more directors but any feedback would be welcome. Thank you.

Way to remove FTS indexes
by Peter Mogensen 19 Mar '19

19 Mar '19

Hi, I was wondering if there was anyway to remove FTS indexes in other to have them rebuild on the next BODY search? All the doveadm commands I can find seem to result in fully build indexes. (which is nice if that's what you want). /Peter

Re: Upgrade from 2.1.17 2.2.36

I use the MAC Foxmail client, v2.2.36 can't receive mail, but v2.1.17 can receive mail. I grabbed the network package and found that Foxmail was not processing the next step after sending the D LIST "" * command. I suspect that because of the time of return, Foxmail is not recognized, so I want to remove this time. 在 2019-03-18 18:03，Aki Tuomi 写道： > On 18.3.2019 12.00, lty via dovecot wrote: > >> v2.1.1 >> >> v2.2.36 >> >> The screenshot is the result returned by imap. >> >> I don't want to want dovecot to return time, can I close it? > > Why do you want this? > > Aki

AD ldap, filter to exclude various kinds of expired, disabled etc etc users
by mj 19 Mar '19

19 Mar '19

Hi, I was revising our AD ldap user_filter and pass_filter to exclude more types of expired / disabled accounts. I started adding things like: > (&(objectclass=person)(sAMAccountName=%n)(!useraccountcontrol=514)(!(useraccountcontrol=546))(!(useraccountcontrol=66050))(!(useraccountcontrol=8388608))) but then I thought, why not simply do: > (&(objectclass=person)(sAMAccountName=%n)(userAccountControl=512)) as 512 would your regular active user accounts only, excluding all other account types. Looking here (https://support.microsoft.com/en-gb/help/305144/how-to-use-useraccountcontr…) there are some many different userAccountControl to check, that it might be smarter to only allow userAccountControl=512, or....? Any ideas on this..? (or examples of how you do it?) MJ
