Re: [Dovecot] force to recalculate quotadict

Hello, > 1. remove the quota in the DB, > 2. make same changes. hmm, i see. but unfortunately this is not a way i can do. it would be acceptable in private scope but not for bussinesscustomers. to make a change i would manipulate customers maildata which is not allowed this way. a simple command to update complete quota for the single user would be the best way. now i tried to connect per telnet and use command Getquotaroot, seems also to work. this should be scriptable... ok thanks, i will try something...

[Dovecot] Saving Sent Messages to Sent Folder
by Charles Marcus 08 Mar '10

08 Mar '10

Hi Timo, There was another thread (it has come up at least a few times in the past few years I've been lurking) on the postfix list about having some kind of automatic 'Save to Sent' option to avoid the users mail client from having to upload messages twice (obviously the only ones of concern are ones with large attachments) - once to send it, and once to save the copy in the sent folder. I know and understand that doing this is not generally the job of the MTA, but hopefully most people can at least admit that there would be a (potentially huge, in the case of any large company that deals with a lot of large attachments in their email) savings in bandwidth (and user frustration) if a way could be found to do this reliably and at little to no 'cost' in terms of CPU/Disk IO, so I have a question about how this might be done... Given: Postfix can be configured to use the Dovecot LDA for delivering mail incoming. My question is simply, why wouldn't it be possible to create a Dovecot LSA ('submission agent'), that could be defined in postfix's master.cf file, which could then be configured to a) pipe the message to postfix, and b) if message is successfully sent, save a copy to the users Sent folder? Obviously, there would be some caveats - ie, postfix and dovecot would both have to be running on the same box (or at a minimum on the same local network)... Anyway, this is just something that really bugs me (and has for many, many years) every time I send a message with a large attachment, and have to watch it slowly process the message sending it, then again to save it to the Sent folder, so Ijust wanted to get your take on if this is even remotely feasible... -- Best regards, Charles

[Dovecot] 2.0 beta 3 w/o libwrap?
by Scott Ellis 08 Mar '10

08 Mar '10

I'm trying to kickstart 2.0b3 on my NetBSD system (where 1.2.x works great!), and keep hitting: Fatal: service(tcpwrap) access(/software/dovecot-2.0beta3/libexec/dovecot/tcpwrap) failed: No such file or directory Indeed, that file doesn't exist...but I don't have nor want libwrap. It appears that doveconf includes tcpwrap... service tcpwrap { chroot = client_limit = 1 drop_priv_before_exec = no executable = tcpwrap extra_groups = group = privileged_group = process_limit = 0 process_min_avail = 0 protocol = service_count = 0 type = user = $default_internal_user vsz_limit = 4294967295 } ...but nothing else seems to. Running configure with --without-libwrap doesn't make any difference (configure doesn't find libwrap anyway). What am I missing here? How can I use dovecot 2.0 w/tcp wrappers? ScottE

Re: [Dovecot] Number of users for one Solr instance
by Lee 05 Mar '10

05 Mar '10

Hi, This is my first mail, fyi. I dont know internals of the plugin but it depends more on Solr than Dovecot. Also the activity level and "real-timeness" of the index is important. Assuming this as the search only machine and relatively moderate usage, a big box with lots of RAM and 4-way server may work in your case. Lee

[Dovecot] Number of users for one Solr instance
by Ernesto Revilla 05 Mar '10

05 Mar '10

Dear all. (I'm new to the list.) Our regional government is considering, due to our proposal, migrate from Courier to Dovecot. 70k mailboxes. One of the most attractive features for them is the usage of indexes, and especially Solr FTS plugin. Their question is: How many users (range of users) could support one Solr instance used as index and search backend? Are there any deployment examples? I think, it would be easy to split users into different Solr instances, but it's not that easy to reorganize them, as we have to reindex if one user is moved from one instance to another. Regards.

[Dovecot] plugin Again
by Alex Baule 04 Mar '10

04 Mar '10

Hello.... Someone know ho work the istream-concat ? I made a copy of istream-concat, and use to manipulate my encrypted body. But i got some questions about the stream->pos, stream->skip and position of the message and pointer to buffer. My messages have the W= with the email size decrypted, and it is a little lass that the email size crypto. For exemple: I have a email with 6000k in crypto and decrypto the size is 5985 k: The buffer from istream-concat is 4096, i read 4096 from get_stream_data, but the result of this read is minor , lets say 4080, but the next read must be from 4096. The "send to client" must be 4080, to send the correctly data decrypted. My Question is, what the variable used in istream-concat, to send the data to client ? I need to update the stream->pos with my data length ?? I dont know if i made understand my question.....

I totally agree with the one of you who mentioned the online documentation and the wiki. I know that it exists and i used it for setting up my mail server, but ... as i said, i am old fashioned and i can better work with books. It's just a personal preferrence. Well, i also know that many developers are still working on dovecot, especially Timo and that always new features, configuration options and so on are added, but ... it's the same with other applications in the community (e.g. postfix, apache, OpenLDAP, samba ....) and for all those applications books are available, and that was the reason, why i asked for a book. And to be honest. When i go thru the documentation part, most of the documents were not changed for at least 6 months. I am sure that between the writing and the publishing of a book new dovecot features will be introduced and not covered in the book. But everyone working with books knows that they can't be up to date, but they are a real good basis for me to start with the fundamentals and then add this information by new data from the web. And guys just to mention one big advantage of a book is, you can read it offline easily!! But there is one thing i want to mention at this point. Even if you agree with me about having a book or not. What i really like is the discussion about and the chance to do so, because dovecot is opensource. And for me this is in the end the result behind the idea of open source. Everyone has the chance to contribute, either by code, by suggestions, by comments ..... And that for me is more important than to have a book or not. Thank you all for your comments.
