Perhaps I have not looked hard enough but is it possible to get at the current users auth userdb "home" (or $HOME) variable from inside a sieve script? Example?

Error: Virtual mailbox loops, Dovecot version 2.2.10
by dan＠redchops.com 03 Apr '17

03 Apr '17

I'm trying to follow the guide at https://wiki.dovecot.org/Plugins/Virtual for the 'Conversation' style virtual mailbox, but with a small change. I'd like the virtual mailboxes to be 'top level', which I found while searching through this list is accomplishable by putting the dovecot-virtual file in the root of the namespace location. My issue is this works perfectly fine for the All Mail virtual mailbox, but the Threaded mailbox fails with the error above. I tried creating a RealMail namespace, but that doesn't solve the issue either. I feel like I must be overlooking something simple; I could get this setup working if the virtual mailboxes shared a namespace and were subfolders, but I don't like that setup much (I'm trying to get my companies GMail users on to our own webmail client, it's features like this that I need to replicate with dovecot or they'll never leave their POP3 setups). I've attached the output of dovecot -n, and my virtual mailboxes look like this: # cat Threaded/dovecot-virtual All inthread refs x-mailbox INBOX # cat all/dovecot-virtual RealMail RealMail/* -RealMail/Trash -RealMail/Trash/* -RealMail/Spam -RealMail/Spam/* all I'd appreciate any insight in to this issue. If I try to access the Threaded Inbox through IMAP, I get this error specifically: a select "Threaded Inbox" a NO [SERVERBUG] Virtual mailbox open failed because of mailbox All: Internal error occurred. Refer to server log for more information. [2017-04-03 00:24:28] The relevant line being: Apr 3 00:24:28 mail dovecot: imap(dan(a)redchops.com): Error: Virtual mailbox loops: No information before or after. Thanks, -Dan

As a wild ass guess, I think maybe the client is using used "STARTTLS" intead of "SSL", or some other SSL requirement disagreement. Joseph Tam <jtam.home(a)gmail.com>

Mail list empty on my mailserver
by Philippe Forums 03 Apr '17

03 Apr '17

Hello, After changing NAS, I meet a problem when I go on my e-mail box with my webmail. Either e-mails do not appear anymore, or they appear but are "empty". When I look in the directory of the e-mails of my mailserver, these e-mails are present. I tried to rename files "dovecot.index*" and to restart dovecot but nothing can be done. To make the seesaw of a NAS towards an other one, I copied all the directory of mailserver to an external storage, and made the copy the other way on my new NAS. This directory is a mount to a NAS. Having well to look, it would seem whether it is a date problem, because the copy did not keep the real dates of e-mails and they thus find themselves dated the day of the copy. I know not at all how to get back all my e-mails in my webmail. Thank's for your help. PS : I'm french, sorry for my english. -- ##################### Philippe - Forums

Is it stable for dovecot 2.2.27 to implement DRBD (or HAST) on block level for maildir data replication instead of using dsync plugin? Regards, George

Slow performance with large folders over the Internet
by Shawn Heisey 31 Mar '17

31 Mar '17

Dovecot package version is 1:1.2.15-7+deb6u1. It is in Debian 6.0.10, using the Debian package. The server is in my basement at home, and is exposed to the Internet so I can fully access my mail from anywhere. I use IMAP for reading mail. I have a number of folders in my mailbox that have thousands of messages in them, from mailing lists. When I'm at home, I have a LAN connection to the server. It goes through a Cisco firewall that limits the connection speed to 100Mb/s. In this situation, I can open a folder with 25000 messages in it, click on the next unread message that Thunderbird did not know about before, and within a second or two, the message will download, allowing me to view it and reply. When I'm at work, with highly variable network latency between Thunderbird and the server, doing exactly the same thing takes a LOT longer. I have seen it take as long as 15 minutes for a single message. If I open a folder with only a few messages in it, it is fast. The server is not overloaded -- I can log into it with ssh and use "mutt -f" to open a folder directly. Loading thousands of messages into mutt takes a while, but I have no difficulty using the ssh connection and running commandline programs. This suggests that the IMAP communication between the server and the client involves a large amount of back and forth communication when the message count in the folder is high, possibly something for every message in the folder. It happens quickly on a LAN but crawls on a connection with high latency. I can understand it taking a few seconds longer on a high-latency link, but it takes minutes. I do plan on building a new server and migrating to Dovecot 2.x, but I haven't had the time to work on that. Is this a known problem? If so, is it fixed in 2.x? Thanks, Shawn

Studying dovecot source code (searching for mail_deliver_hook_set)
by chaouche yacine 30 Mar '17

30 Mar '17

Hello dovecot, I would like to study how dovecot manages quota, especially how it deals with the maildirsize file if one chooses to implement quota according to the maildir++ specification. I made a number of assumptions : 1. mail is (always/sometimes) delivered with the dovecot-lda binary, which source code is in src/lda. 2. mail is sent with the mail_deliver function which is called from src/lda/main.c and is defined in src/lib-lda/mail-deliver.c 3. mail_deliver function calls the deliver_mail function (it seems to be pointer to a function) 4. according to src/lib-lda/mail-deliver.h, deliver_mail is set with the mail_deliver_hook_set function. Here's what the comment says /* Sets the deliver_mail hook and returns the previous hook, which the new_hook should call if it's non-NULL. */ deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook); The problem at this point is that I can't find where is this function called. A grep on the sources only reveals two results : -*- mode: grep; default-directory: "~/DOWNLOADS/APPS/dovecot-2.2.13/src/" -*- Grep started at Tue Mar 28 17:01:50 grep -nH -e 'mail_deliver_hook_set' -r . ./lib-lda/mail-deliver.c:428:deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook) ./lib-lda/mail-deliver.h:103:deliver_mail_func_t *mail_deliver_hook_set(deliver_mail_func_t *new_hook); Grep finished (matches found) at Tue Mar 28 17:01:50 According to the changelog this function has been introduced back in 2010. I don't know if it's really used ? * I am working on the 2.2.13 sources because that's what's installed on my server. * I couldn't find a developers mailling listed in http://www.dovecot.org/mailinglists.html so I'm just posting this here. -- Yassine.

Using SpamProbe via only sieve scripts
by Mark Constable 30 Mar '17

30 Mar '17

FWIW this took me days to get right, and still needs tinkering, but it might make for a good starting point for anyone else needing something similar (ie; I don't use or need the overhead of spamassassin or rspamd). https://gist.github.com/markc/eeeb66ce30ea805af62631656cf86c4d Any comments or corrections on that page would be appreciated.
