[Dovecot] Several issues with 1.0-stable
by Remy Zandwijk 03 Mar '05

03 Mar '05

All, We have Dovecot 1.0-stable deployed in our 3000 users environment as of last weekend. Up untill now, I have 3 issues: - When stopping Dovecot with: kill -TERM `cat /var/run/dovecot/master.pid`, the 'dovecot' process itself dies, the 'imap-login' processes die, but the 'imap' processes (there are a lot of them) don't die, but become a zombie. I think the way I stop Dovecot is the way to do it. The zombies can be killed by doing a 'pkill -9 imap', but that's not quite elegant. - Dovecot is running in a Solaris 9 environment. It turned out that Dovecot crashes when more then 256 filedescriptors are being used. This is rather normal, since Solaris only support 256 descriptors per 32-bit process. After starting Dovecot, I do a 'plimit -n 8192, 8192 `cat /var/run/dovecot/master.pid`, which allows Dovecot to have 8192 filedescriptors. Timo, is it possible to introduce a config file option to configure the number of descriptors? - Pine and Outlook users don't see the adresses or names of the people who sent them email. In my email yesterday, I said I remembered that tests with Dovecot 0.99 showed no problems. Today, I installed both Dovecot 0.99 and 1.0-stable on my test box. It turned out that 0.99 indeed works OK and that 1.0-stable is the problem. The user mailboxes are 'Maildir'; we do not use mbox format. I like to see this problem being fixed..... We have 2 namespaces in our setup: the default namespace and a namespace which location is set to ~/.Mailstorage. When not using a prefix in the email client setup, users can make new email folders in the default namespace and the 'Mailstorage' namespace. We want users only to create mail folders in the Mailstorage namespace, not in the default namespace. Questions: - Is it possible to force a prefix to clients? - If not, is it usefull to have an option in the namespace configuration that allows or disallows the creation of mail folder? If so: consider this as a feature request. Thank you for reading, best regards, Remy Zandwijk Free University of Amsterdam The Netherlands

[Dovecot] Newby Question
by Troy Bull 03 Mar '05

03 Mar '05

Hello I just setup my IMAP server and everything works great, except for 1 small detail. I am upgrading from uwashington's imap server, and in theirs I had to put a directory "mail" in for the imap folder (this is on the client). The problem I have is with dovecot this makes an extra level (I think). So on my server ~/mail is where the mail folder is located, but when the client puts in the "mail" for the imap server directory dovecot looks in and creates folders in ~/.mail/mail. This is a problem for me because I have many clients and I would have to go reconfigure each one. My question is this, is there a way to make dovecot look in ~/ so that when combined with the imap folder from the client it ends up in ~/mail? I hope that is clear enough, I was thinking maybe I need to set default_mail_env, but i have no idea to what? Thanks in advance Troy

[Dovecot] Trigger getmail via mail-client action?
by Gert Brinkmann 03 Mar '05

03 Mar '05

Hello, I want to use dovecot on my private debian/unstable-system to have the advantages of an IMAP-Server (Access to mails from different computers, Simply changing the mail client). I decided to use dovecot, because I very often have read (in the web) that it should be more simple to configure than other servers. Now I have the following question: I want to use getmail to retrieve mails from my provider's pop3-server. I do have a dial-up-connection that is not online permanently (I do not have a flat rate). I could start a script on ppp's ip-up that periodically invokes getmail and on ip-down to kill it again. But I would prefer to invoke getmail only when I really want it to be run. The ideal solution for me was to invoke getmail when the "Get Mail"-Button of the mail client is pressed. Is this possible? Perhaps there is something like a connection- or refresh-trigger in dovecot? Thank you, Gert

Re: [Dovecot] Too many open files, etc.

Martin, we're dealing with the same problem right now. We are using dovecot 1.0 stable and we migrated last weekend. 32-bit processes in Solaris 9 have 256 filedescriptors avail- able. This seems a bit to small. Using this command to get the number of file descriptors used by dovecot: ls -1 /proc/`cat /var/run/dovecot/master.pid`/fd | wc In our enviroment this is currently around 390. You can limit the number of file descriptors per process in Solaris 9. After starting Dovecot, we issued the command: plimit -n 8192,8192 `cat /var/run/dovecot/master.pid` This gives Dovecot 8192 filedescriptors. HTH, Remy

[Dovecot] Protect some mailbox to remove
by FireFly 25 Feb '05

25 Feb '05

I've installed dovecot 0.99.14 (maildir, postfix, RHEL3) and I would like to create , for every user, 4 mailbox (in skel): mail-sent, spam, virus-alert and sysadm. Procmail, parsing header mail, will move mails into a specific mailbox. Every users could move, delete, read these mails but they must not delete mailbox folder (such as INBOX mail). Thanks in advance, Francesco __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[Dovecot] APOP
by Steven Stern 25 Feb '05

25 Feb '05

I want to turn off POP3 and use POP3S in its place. So far, it's working well for Outlook and Thunderbird. But I'm running into problems with Agent: It supports APOP but not POP3S. Is there a way to have Dovecot support APOP authentication on a normal POP3 connection? I'm running 0.99.13 on Fedora Core 3. -- Steve

[Dovecot] A few words about NFS please?
by Jeff A. Earickson 25 Feb '05

25 Feb '05

Hi, Could you say a few words about Dovecot and POP/IMAP to an NFS mounted filesystem? I thought I saw on the dovecot webpage that NFS is "no way" with 0.99 and "maybe" with 1.x. I was looking for the FAQ and couldn't find it. My setup is like so: My mail server is a Solaris 9 system, running sendmail/procmail, and qpopper POP. Mail is stored in mbox format. The /var/mail filesystem is NFS exported to another Solaris 9 system that runs UW-IMAP. The user community also has login access to this second system, so there are also local email clients like Pine and emacs using the NFS /var/mail. So, POP and sendmail/procmail accesses /var/mail locally, while UW-IMAP accesses it via NFS. The user community has been warned to do either POP or IMAP, but not both. There are very few problems with this setup. I would like to use Dovecot for both POP and IMAP on the two machines. I know NFS is frowned upon, but this has worked for me. Comments and suggestions, please? Jeff Earickson Colby College
