similar to: Dovecot as a smart IMAP proxy

Hi all. Currently I am administering a mail cluster in which messages are stored on software RAID shared with NFS. There are several NFS servers, every one of them exports a part of all mail files for a specific frontend with postfix. We are thinking about replacing these storage hosts with one solution, maybe a storage array with appropriate disk space and I/O capacity. What are pros and cons

I'm trying to set up a large scale email system that supports 100,000+ IMAP accounts. We have an existing frontend web interface that does a lookup on a mysql db to figure out which IMAP server to connect to for each user. For the email infrastructure we have decided on Postfix and Cyrus. We have configured both to use mysql to get the virtual user information. Because of the way that the

Hello everyone, I have seen: http://wiki.dovecot.org/HowTo/ImapProxy. It doesn't seem to fit what I need. Unfortunately, I cannot use TLS. I have to use SSL. Also, I would rather not duplicate the certificates for the IMAP servers. Hence nginx doesn't seem to be a good choice either. I am hoping that since SSL has "Client Hello" which specifies the site requested the the

Hello all, I've configured a dovecot server in proxy mode. It seems to work well but. I've tested managesieve with squirrelmail and it's working correctly but I can't connect to cyrus sieve server : timsieved Does anybody here have configure a sieve proxy to do this ? Or is it a normal behavior and dovecot sieve proxy can't speak with cyrus sieve ? Thanks. --------------

Hi. I'm just having a look about aggregating several IMAP sources and a IMAP aggregator proxy would come very handy. I just read: http://www.cyrusimap.org/mediawiki/index.php/Cyrus_Murder_Design and found it very interesting. Anyone did something similar based on: http://tools.ietf.org/html/rfc3656 Thanx.

Hi, There was a discussion a few months ago about a plugin for encrypting email before it hit the disk on the server, and doing transparent decryption while serving data to the client, see: http://www.dovecot.org/list/dovecot/2009-July/041262.html We have a client/user who is interested in such a plugin, and I was wondering if there has been any progress on it yet. In our particular case,

I just committed a very early initial implementation of "imapc" storage backend to v2.1 hg: http://hg.dovecot.org/dovecot-2.1 You can't really do anything except open INBOX and read mails from it, so it's currently only intended for initial testing. It sucks in many ways right now, but I'll be improving it. The idea is that you could set for example: mail_location =

Hi I use dovecot as imap/pop proxy. Is it possible to filter the messages before they get delivered to the client? Thanks for any hint how to achieve this. Mike

Hello everyone. This email makes reference to mail servers and email, but please read the email. You will see that I have some questions about samba. :) I need some feedback and thoughts on a particular setup that "Management" is trying to go with. Some info first: Running Samba 2.2.8a as a PDC with OpenLDAP on the backend. Running a mail server running Postfix, Courier-IMAP,

Hi, I'm considering patching Dovecot to work as a transparent (and virus scanning) IMAP proxy. What is the appropriate feature to extend? (I've considered the following: IMAPC and reverse proxying, with IMAPC looking more promising since it actually parses IMAP communication). Can anyone who is familiar with the IMAPC code recommend what are the most appropriate locations in the

Hello list. I'm planning a new mail servers for our company's customers to replace the oldish Courier-IMAP based one, we already started to deploy some mail accounts on a dovecot-2.0 server as an early test. I'd like to implement the new system with dovecot-2 (I'll probably go straight to dovecot-2.1.x) and I'd like to get it right from the beginning so I'm here asking for

Good morning dovecot users I read in http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy that dovecot need ip address in host field and then "This field is required. Note that currently it's required to use an IP address since no DNS resolving is done.". I use a qmail cluster and Courier IMAP. In this system used the ldap field mailhost for proxy functionality

Hi, we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000 maildirs with ~500GB. Our goal is to do the migration without users have notice and with the shortest service downtime. The users use IMAP (with shared folders and ACL), POP3 and sieve filters. As a first choice, we tried the Dovecot's dsync tool. First tests were great, but we are not able to change the Cyrus auth

I have a proxy setup for pop/imap. The proxies are defined in login_trusted_networks = x.x.x.x and for the imap it works fine but for pop3 connections displays the ip address of proxy IP...

Hi, I will probably have to design an e-mail (and other components) infrastructure for a small ISP soon (WISP). I'm doing some research to determine which components would be best to offer e-mail services to their client and allow the staff to manage accounts easily. I usually use virtual machines a lot for isolation and easy backups and migration (when a hardware node is
