[Dovecot] dovecot 0.99 + apple mail.app
by sean finney 15 Mar '05

15 Mar '05

hello all, first off, a success story. after much testing and preperation, we've switched from uw-imap to dovecot. i am not kidding when i say that we have experienced an order of magnitude decrease in server load (previously load peaks were 40-60, now they are 3-4). so, suffice to say that the mail admins here are very happy :) one problem that has come up though is particular to apple's mail.app. when a client recieves a new message, they aren't notified that it's arrived, and often even when pressing "check for new mail" they don't see it come in. however, if they move from one mailbox to another, and then back, it shows up. it also shows up if thtey completely quit out of the program and start it back up. i'm going to try and get a packet dump of this to see if i can find out what's happening in the conversation, but figured in the meantime i'd put my feelers out to see if anyone else is having this problem. thanks, sean

[Dovecot] dovecot-stable mbox weirdness
by Matt Howard 14 Mar '05

14 Mar '05

I just tested dovecot-stable from 2005-03-08 and 03-12 and saw the following behavior. All of my mbox folders show is the first message's header. None of the files were truncated (whew, saves a restore). I had 0.99.12.1 installed before this, and just switched back to 0.99.14. Both 0.99.x versions work fine. I removed all of the index files to see if there was a hiccup there, with no effect. System is Slackware 10.0. My package was built with this: http://tinyurl.com/6l2vv

[Dovecot] aha! (was apple mail vs. v0.99)
by sean finney 14 Mar '05

14 Mar '05

it seems that when you say "check for new mail" in apple mail, it sends a NOOP to the imap server to get the response. in uw, the conversation is something like: 25 NOOP 25 OK NOOP completed 26 NOOP * 2796 EXISTS * 7 RECENT 26 OK NOOP completed however, with dovecot, if it has already notified the client that new mail has arrived, it will look something like: * 24 EXISTS * 2 RECENT 22 NOOP 22 OK NOOP completed. 23 NOOP 23 OK NOOP completed. (the counts are different because these are seperate accounts) so evidently, apple mail is too stupid to realize to read info from the server unless it asked for it... so now that i think i have a short-term fix (disabling notification for new mail server-side), i can breathe a sigh of relief. for a long-term fix, would it be possible to have the server always notify the client of new mail after a NOOP? thanks, sean

[Dovecot] Authentication error after authentication query (for Eudora 5.2 on Mac)
by Tim Alberts 14 Mar '05

14 Mar '05

Greetings all, I'm a new user of Dovecot and want to say thanks for the great software. I am having a problem at the moment. I run a heterogeneous network with windows and Mac clients logging into a Fedora Linux 2 box running sendmail and previously UW-IMAP, but now Dovecot. I am using strictly pop3, plain authentication with mbox format. Every computer in the network is working fine with this sytem, except 1. A mac running Eurdora mail 5.2. It gives me an Authentication error every time it tries to get mail. I telnet into the server and when I skip the AUTH process and just log in, the server works fine as follows: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ However, when I do the following session: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. auth cram_md5 -ERR Unsupported authentication mechanism. auth login -ERR Unsupported authentication mechanism. auth plain + user tdazey -ERR Authentication failed. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ I don't need any authentication except plain. However, when the client queries the settings, it fails the login. I tried this on multiple accounts with the same results. What do I do to fix this?

[Dovecot] Dovecot, pam and OpenLDAP
by Rune Hamnvik 14 Mar '05

14 Mar '05

Hello We have a Dovecot installation using only pop3 where auth data is stored in OpenLDAP and accessed using pam. With Fedora 2 everything has worked fine, but when we upgraded to Fedora 3 we started to get problems. After a while a lot of dovecot processes existed, and error messages was logged in maillog telling that the processes was too old. Then some error messages telling about memory leak was logged. Our /etc/pam.d/dovecot looks like this: #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth Any idea what is happening?

What problems exist with Thunderbird? Both my wife and I are using Thunderbird with no issues on both OSX and WindowsXP. (No issues that I'm noticing anyway).

I've always had to drop my IMAP connection and reconnect to recognize changes I've made on the server side. A kill -1 to dovecot will only reload the server process and the login auth processes...it won't kill your already established IMAP connection, which as far as I can tell, keeps using old settings. If you are having that many problems, delete all of your subscriptions files and dovecot caches and start from scratch. I've had to do it a few times to get things to work as expected.

[Dovecot] Restrict Imap access
by Sergiu Zaharia 14 Mar '05

14 Mar '05

Hello. I need to restrict access to IMAP ports to a few users, so that all users can use POP3 and just a few of them will be able to access IMAP. I use secure connections POP3s and IMAPs. Is it possible? Also... When I connect to the Dovecot server using Outlook (IMAPs) I get a Warning message,something like: "The server you are connectiing to uses a non verified protection certificate. A chain of certificates ...so on ( I can't translate :) ) Continue using the server? " How can I fix that warning? Thanks

Do you even see the mailbox list? Maybe kmail got somehow confused and recreating the IMAP account entirely would be easiest way to fix it.

[Dovecot] pop before smtp with 'exact' and 'exim4'
by Jools Smyth 13 Mar '05

13 Mar '05

Hello, I just thought I would write this in case its useful to anyone. I've used dovecot for a while, as its so easy to set up, its fast and it and just "works". I recently wanted to be able to send via my server after pop3s authentication. I'm also running debian (testing) which utilises exim4 by default. I found no information about how to do it with this combination of software so went about sorting it out myself. First I got exact : (a pop before smtp daemon) http://adju.st/dist/exact/ After compiling and installing i edited its /usr/local/etc/exact-servers.conf It doesn't support dovecot's log format out of the box, so i created a regular expression entry for it. <server dovecot> order username,address match (Login): (.*) \[(.*)\] </server> I then edited its main configuration, (/usr/local/etc/exact.conf) changing only the user its running on (default mail/mail) to Debian-exim/mail. (so that the state file it creates can be read fine by exim4) I also changed the mail log ownership so that group mail can read them, /usr/local/var/state/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 13 16:39 exact and /usr/local/var/run/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 12 21:54 exact Exact's exim documentation is not for the most recent version, so I had to locate the correct line to modify. I went into the exim4 configuration files. I use the debian split format configuration. In the file /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt there is a line near the bottom which reads accept hosts = +relay_from_hosts I changed this to accept hosts = +relay_from_hosts : net-lsearch;/usr/local/var/state/exact/rela y I then just set exact to and start/stop in /etc/init.d/exim4 thats all!
