The following patches will limit maildir folders to 4000 messages on 
Dovecot 2.0.* and 2.1.*


The Specfile patch is against the Cityfan Redhat EL5 SRPM but is 
likely to work on most build platforms


Changing the message limit requires a recompile. It's brutal and ugly 
but it prevents users overloading FSes that can't cope with huge 
numbers of files (EG: GFS2)




Hi, sorry for the dumb question, but isn't there already in Dovecot a 
way to limit the number of messages?


Something like:

quota_rule = *:messages=4000

Or it's something different?

Not sure how this can be done.

Right now I'm running a free backup MX record service. People point 
their high MX records to my servers and if they go down we store the 
email. When they come back up it's delivered.



Hi, store how? In a queue with smtp server?

What I want to do is have a premium service that would allow them to 
view through IMAP the stored email. In order to do that I would have 
to deliver the email locally to a dovecot server - to a single account 
perhaps - and they can view/forward/delete etc.


But - when their server comes back online I'd like to gather up all 
the delivered email stored in Maildir format and run it back into smtp 
for delivery.


If you store the messages in a queue you can configure your smtp (your 
MX) server to send a copy of all message it receive also to another 
mailbox,  see always_bcc in posfix.

You are completely right, I simply don't like the idea to have one

Could have completely missed the point, but this way you get a shared 
pool of frontend machines (so might as well spam/av block on them), 
which then use a transport map to get the mail internally to the 
correct mailbox server.  You can obviously also use a similar sql 
query to ask Dovecot frontend servers to proxy connections to the 
correct backend server...




I already have a pool of frontend server (MX) that do AV/Spam filtering 
and a transport map to the internal machine, but I don't do any query, I 
verify the existence of the recipient via recipient address verification 
before queue with Postfix.


I think - for now - I will try authentication with multiple database 
with Dovecot, by now I only have 4 internal servers with MySQL, so 
performance I hope will not be a problem considering that Dovecot cache 
the results.


I can also implement a procedure that periodically extract only 
user/password from the internal DB and export them to the smtp auth db 
servers, but it's not in real time and may be I'll encounter some 
locking/performance problem during export/import.

[Dovecot] SASL auth and proxy

2010-09-29 Thread mail...@securitylabs.it 
 Hello, I'm finding a way to have a pool of smtp-auth servers in front 
of my actuals servers to permit relay to our customers. Now users sends 
emails connecting to the right IP via mail.domain.tld, with 
authentication. Every server has it's own user database in mysql.


I'd like to have a pool of server (with round robin, ideally with 
postfix + sasl + dovecot) that authenticate the users with the actuals 
servers and then pointing mail.domain.tld to this pool and not to one 
server.


My trouble is how to authenticate users.

Can I use:

http://wiki.dovecot.org/Authentication/MultipleDatabases

to tell Dovecot to authenticate with every MySQL database on the servers 
"behind"?


If yes, is there a better way to do this considering I'm already using 
some proxy machines (dovecot) for pop3/imap and so I already have a db 
with domain.tld -> IP of the server? I also have some machine without a 
MySQL DB for users (vpopmail + cdb), so the option with 
MultipleDatabases will be good only for some machines.


Something similar to the proxy mechanism that I already use for 
pop3/imsp will be good: the proxy connect to the machine behind that do 
the authentication, I only need a table with domain -> server IP (that I 
already have).


Thanks for any advice.

Hello, dunno what filesystem you are using. If it's ext3/4 I suggest you 
to mount it with noatime option.


Accessing a large Maildir folder with atime it's a pain. On an old

load to < 5 only remounting with noatime option.

Good news and bad news.

The good news is that I've been core dump free for about 24 hours. The

The bad news is that I'm now convinced that another problem I've been 
experiencing is real and not related to any of this since it's still 
persists.


Randomly for a few releases now myself and my coworkers have been 
seeing a weird bug where old mail marked as "read" suddenly becomes 
marked as "new" again when going into a folder. Sometimes it's as bad 
as the entire folder deciding it is all unread when in fact is was all 
read, other times it's randomly a few pieces of mail that constantly 
revert to unread status. I've watched this on my personal server as 
well as heard complaints from our user population.


I don't believe this is an NFS issue because my personal account is a 
standalone server with both a local index and maildir running 1.2.9. 
Also, I'm only ever connected from one place at a time. Just this 
morning when I got to work I logged in with Thunderbird and my 
"dovecot" mailing list folder suddenly had 3,000 new messages in it, 
all of which had been previous read. I marked the folder as read, then 
a little while later I went into the older and they all reverted to 
new again. I've also seen it where if I try deleting one of these 
messages marked as new, it disappears for a second, then magically 
reappears in my folder as new.


Unfortunately, I'm not seeing a single log message related to this. As 
you can tell, I watch the logs like a hawk, yet nothing ever appears 
to throw an error or any message whatsoever. All my test cases have 
been with Thunderbird 3.0, I'm not sure if other clients a

re seeing this.


Hello, same problem here. I use Thunderbird 3.0.1. The strange thing is 
that with the same version of TB on my PC at home I don't have this 
issue. The same TB on my work PC has this issue and only on one account 
(that has Dovecot as imap server) but I have other account (some with 
dovecot, other with courier-imap) where this does not happen, so I think 
is TB related.


Also here no NFS, ext3.

Yes. Return mail_plugins setting from your user_query. For example:

Did you migrate to Dovecot from another server? Sounds anyway like TB is configured to 
have "INBOX." namespace prefix or something like that. Or possibly it's caching 
wrong hierarchy separator and you need to recreate the account in TB.
  

With a different version of TB on another computer this does not happen, 
tomorrow I will try to recreate the account on the problematic TB.

Thanks, Igor
