[Dovecot] problem with charset and encoding
by Héctor Moreno Blanco 15 Mar '13

15 Mar '13

Hello everyone, We are having some troubles since we updated dovecot from 2.0.10 to 2.1.6. With 2.0.10 with messages with this headers: Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Showed the special characters fine. However, with this new version, there are special characters that are not correctly showed. For example: "Su c=F3digo de activaci=F3n " must be "Su código de activación ", but in all email clients, even in webmail, is showed like the first way without decoding it. Maybe some configuration or libraries I missed? Could you please help us with this? Thank you very much in advanced. Kind regards, Héctor Moreno Blanco.

[Dovecot] Converting from Cyrus -> Dovecot sdbox
by lst_hoe02＠kwsoft.de 14 Mar '13

14 Mar '13

Hello we like to convert a IMAP server with Cyrus 2.2 to Dovecot 2.0.19 and sdbox mail format. From what i have read until now this is a two stage process with converting first from Cyrus to (Dovecot) maildir with for example cyrus2dovecot and than with dsync from maildir to sdbox. Is this correct or are there other possibilities to go in one step from Cyrus format to sdbox? Regards Andreas

[Dovecot] stats plugins causing dns lookup per connection
by Kelsey Cummings 14 Mar '13

14 Mar '13

I noticed our imap servers were generating a lot of A record lookups for their own IP's the other day and just got around to tracking down the source. Seems like they are all being caused by guid_128_generate() - perhaps the lookup could be cached at start up or it could just use make use of the hostname rather than spending the effort to get the IP via gethostbyname() calls. The function is used in a few other places too, so this might help more than just the stats plugin. nscd and/or host entries mitigate the total time spent on the lookup of course, but it seems unnecessary. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

[Dovecot] Sieve mark message as read
by Donny Brooks 13 Mar '13

13 Mar '13

I am trying to get the advanced functionality of managesieve working for our users. If this is not the proper place to ask this, please just say so. I have enabled sieve and it works just fine for basic moving messages to folders. However the problem comes in to play when a user selects something like "delete" or "mark as read" in the filter. It just simply does not do that function. I have installed the imapflags and imap4flags and added the needed parts to the dovecot config but it still does not seem to work. We are running Centos 6.3 with dovecot-2.0.9-2.el6_1.1.x86_64 and dovecot-pigeonhole-2.0.9-2.el6_1.1.x86_64 installed. What could I be missing to make this work? -- Donny B.

[Dovecot] Qmail-LDAP/Dovecot Cluster
by Jeff Hardy 13 Mar '13

13 Mar '13

Hello, I have worked with qmail-ldap and Dovecot for a number of years, and recently wrote up a piece going into great detail about all aspects of our environment. It currently supports a rather small installation of ~10K active users. If it should be of interest: http://fritz.potsdam.edu/projects/email It is intended primarily for system administrators or mail administrators interested in building mail infrastructure on top of open-source technologies, and is inspired by the likes of Life with qmail. Topics include storage, backup, directory integration, local and remote mail exchange, checkpassword SMTP-Auth and Dovecot login, RBLs, content-scanning and anti-spam, quarantine, webmail, etc. Full installation directions and configuration stanzas are provided for nearly every piece of the infrastructure. Comments/criticism welcome. Cheers. -Jeff -- Jeffrey M Hardy Network / Systems Administrator hardyjm(a)potsdam.edu

[Dovecot] mail_max_userip_connections
by Simon Brereton 13 Mar '13

13 Mar '13

Hi Sometimes, I hit mail_max_userip_connections limit. As far as I know I'm the only person that does, but I would like to find out why before someone else hits the limit. Is there a command available that can list the connections per IP? I'd like to find out which client is causing this. Or do you have a better suggestion? Should I just raise the limit (it's still at the default 10, which I never changed). What are the implications of this. Thanks. Simon

[Dovecot] Limiting size of stored emails
by Patrick Joy 13 Mar '13

13 Mar '13

Hi, Would appreciate some advice on this issue. I'm running dovecot version 1.0.10 on ubuntu 8.04 LTS. Recently a user created a draft email in their client (outlook) and added a 4GB attachment. The email was uploaded to the draft imap folder on the server. After this the client would then go into a endless synchronisation loop every time outlook was opened. For example in the most recent case 400GB of data was downloaded to the client when the user left outlook synchronising for 5 days. I know this may be a bug with the client or client os however I would like to know if there is a way to limit the size of individual emails that can be stored in the imap store to prevent users creating huge drafts. There is no reason they should need an email draft of this size as it can never be sent through SMTP. Thanks

[Dovecot] Documentation Clarification
by andreas＠cymail.eu 12 Mar '13

12 Mar '13

Can somebody please clarify the following in the documentation? I am actually looging at the 2.x docs: In the http://wiki2.dovecot.org/Authentication file there is a good effort to clarify between authentication mechanisms and password schemes. The authentication mechanisms are described in http://wiki2.dovecot.org/Authentication/Mechanisms. That is fine. But then looking at the http://wiki2.dovecot.org/Authentication/PasswordSchemes there is a section "Non-plaintext authentication mechanisms" which looks to me to be a repeat of what there is in the description of the authentication mechanisms. This section lists one more mechanism, LANMAN. Can somebody explain why this section is in this file? And which of the two is applicable. Thank you Andreas
