[Dovecot] fedora rpm for 2.0 beta?
I'm looking for a spec/rpm file suitable for fedora 11/12, for dovecot and pidgenhole sieve. Has anyone done this yet? Otherwise I will attempt to the dovecot 1.2 spec files for f11. -- Joakim Verona
[Dovecot] architecture to handle 1000 messages per second?
Can anyone describe an architecture which can handle 1000 IMAP or POP messages per second? Ideally, it would be hosted in the cloud and additional instances could be launched to handle additional load. Bob

How about delivering the messages to multiple different servers, then your app connects to all of the servers separately and downloads the mails? As to how to get them to different servers .. maybe it would simply work to add/remove MX DNS records as needed?

Hi Bob, Just to make sure I understand you: Some app is sending emails to ord...@example.com at the rate of 1000 per second, and another app is fetching email from ord...@example.com to process them?

[Dovecot] What auth ?
Hello people, First of all a Happy New Year and best wishes to you all. I've managed to setup dovecot v1.2.9 on a CentOS 5.4 system and I am now, trying to make it auth. I would prefer virtual users and only want to make the IMAP/ IMAPS part work. I don't need POP3 or anything else. The rest will be handled by another SMTP/POP3 application. Now, I almost managed to make dovecot auth a virtual user with his password. However, when it seems it has passed the auth stage (either via IMAP _or_ IMAPS), the command line kicks me out. Here's roughly what I did : 1. Created /etc/dovecot/users and /etc/dovecot/passwd 2. filled in a couple of usernames/passwords encrypted in MD5 format 3. Ran dovecot from command line (service dovecot start [after I created the service ofcourse]) 4. telneted to localhost via port 143 or 993 (with the help of openssl: openssl s_client -connect the.system.name:993) 5. typed : . login usern...@fqdn password Something worth noticing for step 5. If I do this logging-in with the u...@fqdn format, the systems kicks me out. I, then, check the latest on /var/log/dovecot/errors to find that the system does not complain about the auth. If I do the same logging-in but instead use u...@localhost (and not the fqdn), the system fails the authentication stage and does _not_ drop me into the shell. Go figure !! Anyway. My question, in essence, is this; Which type of auth should I use ? The manuals (that i've been sinking my head for the last couple of weeks) suggest I should use PAM. PAM, I cannot understand. At the moment, I _think_ I am using MD5. Any pointers here ? I've been reading the /doc/wiki directory for quite some time until it made no sense to me anymore (too much info makes me loose perspective). Any help would be greatly appreciated. TIA, spyros

Ideally, it would be hosted in the cloud and additional instances could be launched to handle additional load. Bob The Courier IMAP server is a fast, scalable, enterprise IMAP server that uses Maildirs. Many E-mail service providers use the Courier IMAP server to easy handle hundreds of thousands of mail accounts. With its built-in IMAP and POP3 aggregation proxy, the Courier IMAP server has practically infinite horizontal scalability. In a proxy configuration, a pool of Courier servers service initial IMAP and POP3 connections from clients. They wait to receive the client's log in request, look up the server that actually holds this mail account's mailbox, and establish a proxy connection to the server, all in a single, seamless process. Mail accounts can be moved between different servers, to achieve optimum resource usage. http://www.courier-mta.org/imap/
[Dovecot] Recalculate quota usage on demand
I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] Using Push IMAP to trigger POP3 download
Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be pushed a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to piggy back off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid!

For example, GNU Mailman is mailing list software which pipes each incoming list message to a Python script. That command can then perform the necessary processing. I don't know what you had in mind, but if the messages can be handled independently, it's easy to add new machines. Just duplicate the config on another box, and create an MX record for it. virtual_alias_domains - # Each address in example.com must be aliased to a local user. example.com IGNORED virtual_alias_maps - # The virtual address ord...@example.com is mapped to the local user # of the same name. ord...@example.com orders alias_maps - # And then the local user's mail is delivered to a script rather than to # a mailbox. orders |/path/to/your/script
[Dovecot] Deliver virtual user's mail to a specific namespace?
Hello:
I have virtual users set up for the various mailing lists that I
subscribe to. Everything has been working well in both Postfix and
Dovecot. Postfix is configured to deliver to a specific mbox file within
my mbox mail root. I can access retrieve and read email via Dovecot
without any issues.
Now I want to make my setup more robust and have these messages
delivered to a maildir namespace.
I have configured the LDA within the Postfix master.cf file:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f
${sender} -d ${recipient}
I have configured the 'dovecot' transport within Postfix in the
transport file:
t...@lists.schang.net dovecot:
In dovecot.conf I have set up the namespace as follows:
namespace private {
separator = /
prefix = Lists/
location = maildir:~/MailLists
subscriptions = yes
}
I'm having a hard time specifying the Lists/ namespace in my userdb
passwd-file:
test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test
I can't get the userdb_mail portion to work. For this user,
't...@lists.schang.net', how do I tell Dovecot/deliver to put the
message in the 'test' mailbox within the 'Lists/' namespace?
I'd appreciate any insight.
Thank you.
