...list. It looks like the code is almost working, but it's still giving failures once in a while. Below are anyway a few benchmarks for you to see how it's progressing. I haven't yet done all the optimizations I've planned, but looks like it already gives 25-30% better performance in cydir tests. The cydir benchmarks are the most important ones because cydir relies completely on index files, so the benchmarks are practically index benchmarks. And the 25-30% is mostly about CPU usage I think, reduced dovecot.index file rewrites will help with disk I/O as well. The new index code shou...

Hello, >From what I have read on the dovecot site, it's possible to create a plugin for a custom data store format. We have emails in a custom format in a database and would like to create a plugin for accessing these emails through dovecot. Is there any supporting documentation from creating a plugin like this? Are there any samples? TIA, Gary

I thought I'd try benchmarking with dbmail (v2.2.4) to see how much slower a SQL backend could actually be. Skip to bottom for the conclusions. Originally I ran the tests with the databases being in XFS filesystem. MySQL's performance was horrible. It went 3-7x faster with ext3. MySQL 5.0.30 backend (innodb): ./imaptest clients=1 - append=100 seed=1 secs=30 msgs=1000000 logout=0

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed mem...

Also I would be interested to know the applicability against mailbox formats: mbox / maildir / sdbox / mdbox / cydir. Also I would be interested to know which data gets moved to the alternate storage, and which data stays in the main storage: message-data / control-data / index-data / combined-control-and-index-data. Also I would be interested to know how data can be moved to alternate storage. Seems to be t...

Hello, I'm a software programmer and I work for a software corporation. We worked on dovecot for a while. We want to add some new functions to dovecot. For example, the mail stored on Mail-Server is plaintext, so we want to make it encrypted. As the documentation was not too much, and read the source code was too difficult for em. Would you give me some advice if I make this specialty as a

Hi! I'm starting to read and play with dovecot since a month ago. But my mailboxes' format is hashdir, which has been implemented here by my team. Here: http://wiki.dovecot.org/MailboxFormat I've noticed that "Adding support for new formats for Dovecot isn't very difficult, although it can be time consuming. Dovecot exposes a nice and simple API which needs to be

Hi I intend to write a new virtual backend for dovecot. Are there any hacking docs describing how the code is organized, eventually also important structs and how to hook myself into the system, or do I have to go the classical way? Thanks --Flavius
