[Dovecot] auth failure
by Tom Allison 11 Jun '04

11 Jun '04

well, with some help I've made a fair amount of progress on my box. It's working out much easier than I had anticipated and perhaps my notes will be useful some day. I have two questions... Here is where I am: cling:~# egrep -v "^($|\#)" /etc/dovecot.conf protocols = imap imaps login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 verbose_proctitle = yes default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pgsql /etc/dovecot-pgsql.conf auth_user = root auth_verbose = yes cling:~# egrep -v "^($|\#)" /etc/dovecot-pgsql.conf connect = dbname=dbmail user=dbmail_reader password=SECRET default_pass_scheme = PLAIN-MD5 password_query = SELECT passwd AS password FROM users WHERE userid = '%u' I've created working passwords using 'mkpasswd --hash=md5' and plugged the results into my database. I can login and everything looks pretty cool. Except, as near as I can tell, I'm sending plaintext authentication over the wire. My best guess is that my password gets munged into digest-md5 format before it goes over the wire. At this point I'm of the opinion that I'm reasonably secure. True so far? My guess is that the next step in security is to go for imaps and ssl configuration. But my debian installation doesn't appear to have the dovecot-openssl.cnf file referenced in the configuration.txt file. Is this missing from dovecot or am I looking at a debian problem?

[Dovecot] Corrupted index file
by Niilo Kajander 11 Jun '04

11 Jun '04

Hi, I've been wondering for a while if reiserfs is dovecot+maildir safe or not. I get this too often (and my imap session gets disconnected): Jun 9 08:42:32 sun imap(nk): Corrupted index file /home/nk/Maildir/.INBOX/.imap .index: UIDVALIDITY changed in uidlist This happens always when a new mail arrives in maildir. It's a Fedora Core 2 box running dovecot-0.99.10.4-4 (redhat) package. Could the reason for these corruptions be something else than reiserfs? I know there has been some problems with Fedora+dovecot but I haven't seen this one reported here. TIA, -- Niilo Kajander <nk(a)kajander.fi>

[Dovecot] bleah
by Tom Allison 11 Jun '04

11 Jun '04

Not to be a bitch, but I've asked several times about some basic questions or examples to clarify the essentials for configuration. What do some of the parameters mean? Expecially the ones that are mentioned only one in a paragraph and no where else in the documentation or wiki. (ie: login_process_per_use) And there have been a few others as well. that I won't bother to repeat. But I've been sitting on this list for a while yet and have found that when it comes to configuration, none of the emails posted have been answered or addressed. The closest I got was a suggestion to use views instead of tables in postgres. But technically nothing was ever said about dovecot itself. So I have to ask. Is the sketchy documentation in the source file, the web page, wiki, and limited reponse on the mailing list a matter of "I haven't gotten around to it yet" or a deliberate move to promote the commercial support potential for Procontrol? I've run into this kind of environment twice before (cyrus and razor) and in the case of cyrus they just didn't believe in doing the documentation but suggested I write it myself. That may be the case there as well ("I haven't gotten around to it yet". That's OK but cyrus has the difficulty of no one still not providing any answers to how anything was done, configured, functioned, or why. So documentation was kind of a reverse-engineering project in itself. In the case of razor it's a mix of no time and they would rather support the company than the project. I went back and re-read the emails that I had posted earlier and am pretty sure that they weren't too stupid (ie: how do I test an imap connection), difficult, or obscure (well, maybe one). I'm just trying to find more information on how to correctly configure this server such that I can retain the concept of keeping security in mind. I'm trolling through the archives and there doesn't seem to be much discussion from anyone else. So maybe I'm really stupid and can't do authentication schemes. I'm sure by this point I've really pissed a few people off and for that I mostly apologize. I'm a little bent here myself. It just that I didn't plan on having to set up sniffit to track my IMAP traffic in order to verify that things were actually working securely. I'm going to plug along and do it myself and probably get something to work. I have plain_text authentication working now, but was really hoping to actually get something secure. At this point I really don't expect an answer, but do hope that after 1.0 is released there will be time available to get some documentation in order. IMHO the level of documentation that is available on a software project is critical to it's use.

[Dovecot] pgsql documentation

From dovecot-pgsql.conf # Examples: # connect = host=192.168.1.1 dbname=users # connect = host=sql.example.com dbname=virtual user=virtual There is a reference to identify the rest of the parameters via libpq in the postgres documentation. From postgres, libpq says the connection environment variables are: hostname:port:database:username:password http://www.postgresql.org/docs/7.4/static/libpq-pgpass.html Should the dovecot-pgsql.conf docs be changed from "dbname=users" to "database=users" ??

[Dovecot] "virgin" mail accounts
by Christian Balzer 11 Jun '04

11 Jun '04

Hello, I'm willing to swear that with the 0.99.10.4 Debian package in my rather extensive tests with mailbox format dovecot created not only any missing parental directories but also the INBOX file, but the later I can't prove/test now as I upgraded all respective boxes. However 0.99.10.5 will still create (if needed and possible) missing directories for mbox storage, just not an empty INBOX. But with maildir, it will not even do that, from a test with pop3 and imap login attempts to a freshly created account that had not received any mails yet: --- Jun 10 12:58:03 mb01 pop3-login: Login: test [203.216.5.92] Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8050ce0 (0) Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8084aa0 (1) Jun 10 12:58:49 mb01 imap-login: Login: ttest [203.216.5.92] Jun 10 12:58:50 mb01 last message repeated 3 times Jun 10 12:58:50 mb01 dovecot: child 9193 (imap) killed with signal 11 --- It died not very graceful in either case, esp. the later. Unless there are very RFC'ish and imperative reasons, I'd suggest that dovecot creates all missing bits if possible no matter what the storage method or pretends to have encountered an empty mbox file or maildir cur/new respectively. The rationale should be obvious, no frantic user calls about "My mail is not working" when the answer is "Duh, that's because you never ever received one yet". ;) Regards, Christian Balzer -- Christian Balzer Network/Systems Engineer NOC chibi(a)gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

[Dovecot] 2 problems
by Cor Bosman 10 Jun '04

10 Jun '04

Hi all, im testing dovecot as a replacement imap server and noticed 2 problems in 0.99.10.5. if you use dovecot/pop on an account who's quota is fully used, dovecot will ungracefully stop. This will only happen when the account is first accessed by dovecot (for instance, when offering IMAP to an existing userbase using dovecot, or when the index files have inadvertently been deleted). +OK dovecot ready. user scorpio +OK pass xxxxxxxx +OK Logged in. Connection closed by foreign host. The same goes for imap: * OK dovecot ready. . login "scorpio" "xxxxxxx" . OK Logged in. . select INBOX . NO Out of disk space This is a bit of a problem because one of the remedies of solving an out of disk space problem is deleting email, which you cant now. Cor

[Dovecot] mbox configuration

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view any thing other than inbox. I am still able to see message in inbox since I haven't change the location of inbox. Please help. Nina

[Dovecot] authentication configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've included the non-defaulted bits of my dovecot.conf file at the bottom of this email. As I understand my set-up it's using unix authentication methods (/etc/passwd via pam?). Considering disable_plaintext_auth and auth_mechanisms, what exactly is being passed? I was hoping to get auth_mechanism = digest-md5 but that's not working out very well right now. It seems I can only do plaintext authentication. I got stuck on the userdb/auth_passdb settings. Can someone give me an example of how to configure for md5-digest authentication? My current guess is: disable_plaintext_auth = yes auth = digest-md5 auth_mechanism = digest_md5 auth_passdb = /etc/mydigestfile How would I set this for pgsql? auth_passdb = /etc/dovecot-pgsql.conf ### non-default config settings. protocols = imap imaps disable_plaintext_auth = yes login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pam auth_user = root

[Dovecot] configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've noticed that there are some parameters mentioned in the docs that aren't identified therein (ie: login_process_per_use). Is there a more generic set of docs that can identify what each of the parameters and what they do, or at least something that will allow me a simple how to to avoid embarrasing situations. I supposed I should only settle for ssl based connections (imaps/pops) but I will be open to digest-md5 if I could. I'm also curious to see how I can use pgsql authentication with dovecot. I think this would be great to work with since I'm basing all my postfix settings around postgresql as well. But for now I'm not sure how to use postfix authentication with the file directories I'll need to use for the maildirs (and procmail!).

[Dovecot] pgsql configuration
by Tom Allison 10 Jun '04

10 Jun '04

from the pgsql configuration file: # Query to retrieve the password. # # The query should return one row, one column. If more than one row or column # is returned, authentication will automatically fail. # # Available substitutions: # %u = entire userid # %n = user part of user@domain # %d = domain part of user@domain # # Query to retrieve the user information. # # The query must return only one row. The columns to return are: # home - Home directory # mail - MAIL environment # system_user - System user name (for getting user's groups from /etc/group) # uid - System UID # gid - System GID # # Either home or mail is required. uid and gid are required. If more than one # row is returned or there's missing fields, login will automatically fail. # I'm a bit slow here, so if someone could just nod if I'm in the right direction: I want to support IMAP for at least two domains. Therefore I have to use the authentication string of: SELECT password FROM users WHERE userid = '%u' and the user must enter their entire email address for their login name. (I can do this!) I want some portion of these domains and users to be consistent with existing accounts in my /etc/passwd database. I don't expect to use passwd information for the username and password, but I want the information returned for joe(a)domain2.com to be for the user:joe in my passwd file and have his email in /home/joe/Maildir. Similarly, I want others (either fred(a)domain2.com or jane(a)domain1.com) to be (ideally) all driven under a non-local account name and login. For this second one, I'm thinking I need to do something like this in the user information query (this is mostly a guess): for joe(a)domain2.com (/etc/passwd) :: jane(a)domain1.com (no passwd) home - /home/joe --or-- can I use ~/ :: /var/spool/imap/%d/%n ?? mail - maildir:~/Maildir :: maildir:/var/spool/imap/%d/%n ?? system_user - joe :: (a guess -- adduser dovecot-imap to passwd maybe) uid - joes uid (1002) :: dovecot-imap uid (510) gid - joes gid (1001) :: dovecot-imap gid (510) with seperate group This is where I get fuzzy. If someone could help me figure out where I went wrong I would appreciate it. If I did this correctly, then in theory I could pass email delivery to procmail and have one set of rules (/etc/procmail) do some additional filtering for all the email under my domain1.com (spam filtering mostly) and perform a final delivery to maildirs in /var/spool/imap/doamin1.com/jane/ Or am I sleep deprived?

[Dovecot] dovecot newbie question about "invalid key" problem
by Joakim Verona 10 Jun '04

10 Jun '04

Hello list, I've trying to migrate a small uw-imap server to dovecot. It works somewhat, and speed seems greatly improved, so thats great. However, I get an "invalid key/Internal Error" problem when connectiong to my INBOX with thunderbird. According to google this is a well known problem with mozilla mailers. Dovecot is not lenient with this bug in thunderbird. Is there some workaround for this? I noticed that its possible to turn on some client bug workarounds for outlook. Does the same go for mozilla? I tried one described remedy, which was to delete the account information and re-register the account. This didnt help. The problem seems to be only with INBOX, which I have mapped to /var/spool/mail/<username>, not my other imap mailboxes. Im running gnus as well and the problem doesnt seem to occur there. My configuration: Redhat 9 dovecot 0.99.10.5 (from DAG repository RPM:s) Another question: Would it be possible to run uw-imap on one port, and dovecot on another? Or would that corrupt the mailstores? Regards, /Joakim

[Dovecot] Feature request?
by Stephen K. Gielda 10 Jun '04

10 Jun '04

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop access is denied. Is this something that can be considered for a future feature addition? Would anyone else also find this useful? /steve

[Dovecot] Help: RH9 upgrade (mbox)
by Guy Davis 09 Jun '04

09 Jun '04

I just upgraded my RH9 server with UW-IMAP to Fedora Core 2 and after a short try with Cyrus, I'm hoping to get Dovecot configured. My problem is getting Dovecot to recognize my old mbox mail folders. It correctly shows the INBOX contents from the /var/spool/mail/davis mbox. However, I also had a bunch of mboxes such as: /home/davis/Mail/Sent /home/davis/Mail/Lists/list1 Reading the documentation, Dovecot indicates it will recognize mbox files within the ~/mail directory. So I moved my mail over giving: /home/davis/mail/Sent /home/davis/mail/Lists/list1 Unfortunately, after restarting Dovecot and restarting my IMAP client (Mozilla), I don't see anything other than my Inbox. If I create a file (/home/davis/mail/.subscriptions) with 'Sent' in it, and restart things then I can see Inbox and Sent. This would let me have a single directory with multiple mbox files in it. However, I'm not able to get Dovecot to recurse and let me see mboxes in subfolders such as: /home/davis/mail/Lists/list1 As well, when I first connect to Dovecot via Mozilla, I get an error saying: 'The current command did not succeed. The mail server replied "Invalid mask"'. What does this mean and how do I correct it? Any help would be greatly appreciated. Thanks, Guy

I'm trying to set up dovecot to use /home/username as IMAP root, but it keeps creating /home/username/mail. I need /home/username in order to migrate with the least changes from uw-imap, just by copying .mailboxlist without the INBOX line in it into .subscriptions I tried each of these, one at a time: default_mail_env = mbox:~/:INBOX=/var/mail/%u default_mail_env = mbox:%h/:INBOX=/var/mail/%u default_mail_env = mbox:/home/%u/:INBOX=/var/mail/%u In each case, dovecot was stubornly creating /home/username/mail Please CC me, I'm not on the mailing list.

[Dovecot] mta/mda config
by Jure Pecar 04 Jun '04

04 Jun '04

Hi all, I'm at the stage of planning our new mail system and am evaluating dovecot for it. For large mailstore setups, it makes sense to split maildirs across many directories. I see that setting default_mail_env to something like maildir:/var/imap/domain/%1d/%d/%1u/user/%u/ would create almost identical on-disk layout as multidomain cyrus setup. Now, as dovecot does not have its own mda or lmtp daemon, how does one configure mta (eg. postfix) to deliver mail in such maildirs? Related question ... any cyrus to dovecot migration tales? :) -- Jure Pečar

[Dovecot] Advice on converting from Mbox to Maildir?
by Villalovos, John L 04 Jun '04

04 Jun '04

Does anyone have advice or pointers on good documentation on how to convert a system from using the Mbox format to using Maildir? I recently upgraded to Fedora Core 2 from Fedora Core 1 and discovered that UW-IMAP was gone. So I switched over to using Dovecot. So far so good. But I would like to convert my system to start using the Maildir format. How easy is this to accomplish? Can I keep my Inbox /var/spool/mail/user_name as an mbox format and have my other folders as Maildir? What would I have to change for Sendmail to make it use Maildir for the Inbox? Can procmail support Maildir? Any pointers or help would be much appreciated? John

I am using dovecot-0.99.10.5-1 which was on the development tree of Fedora. Though I would think the one that came stock with Fedora 2 should work as well. I have no reason to think it won't. One note. I don't use POP that much. I have one person who uses it and they haven't complained. > So if all the mail is moved to Maildir (thus eliminating the typical > mailspool), and somebody pop's onto the server, Dovecot will use the > Maildir/Inbox for the pop? Yes it will. If you read the mail-storages.txt documentation file it talks about it. I would read the section on "Detecting what to use". I did NOT set the default_mail_env variable in my /etc/dovecot.conf and it figured it out automagically :) Good luck, John

[Dovecot] 0.99.10.5 imap flag update issues

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a move. And, while I am at it, (3) I see a regular log entry from a MS Outlook 2000 SP 3 Jun 3 10:26:23 bounce imap-login: SSL_read() syscall failed: EOF [130.83.XXX.XXX] The setup here: OS NetBSD 2.0beta, MTA sendmail 8.12.11, LDA maildrop 1.3.9, dovecot 0.99.10.5, OpenSSL 0.9.7d Any ideas? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281 / \ Respect for open standards

[Dovecot] Getting POP3 up and running
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! Now that I happily smiling have Squirrelmail working on the new setup (Fedora Core 2), the next hurdle seems to be getting POP3 to work. According to my understanding of the documentation I changed the protocols line in dovecot.conf to: #protocols = imap imaps pop3 pop3s then restarted dovecot, but still can't connect to pop3 (not even after rebooting the whole system). Doing an nmap on my server does not show port 110 as open. Any clues as to what I may be overlooking? Thanks for your support, Antonio There is a world of difference between searching for happiness and choosing to be happy!

My suggestion would be to use Dovecot as your POP and IMAP server. And convert everything to use Maildir unless there is some special reason you want to keep mbox format for.

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Fairly easy on the small system I had.

Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that.

[Dovecot] Serve list archives by dovecot IMAP
by Kenneth Porter 02 Jun '04

02 Jun '04

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora
by David Keegel 02 Jun '04

02 Jun '04

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols. That is a lot easier for me than getting source, patching it, re-compiling and re-installing. We are using Fedora Core 1 (fedora-release-1-3 i386 rpm) Dovecot 0.99.10 (dovecot-0.99.10-4 i386 rpm) OpenSSL 0.9.7a (openssl-0.9.7a-33.10 i386 rpm) ___________________________________________________________________________ David Keegel <djk(a)cybersource.com.au> http://www.cyber.com.au/users/djk/ Cybersource P/L: Linux/Unix Systems Administration Consulting/Contracting

[Dovecot] Postfix SASL AUTH from Dovecot
by Timo Sirainen 02 Jun '04

02 Jun '04

Again today got annoyed at Cyrus SASL. Upgrading it to newer version had broken PAM support. Trying to login as "user@domain" resulted it only asking for "user" from PAM. Well, got it patched and working again, but I'd rather not go through it all the time.. So I finally did what I had been thinking about a year or so, change Postfix to use dovecot-auth directly. This required cleaning dovecot-auth quite a lot, but it seems to be working now. Actually I finally implemented support for initial SASL response as well. POP3's AUTH command had required support for it, strange that no-one ever complained about it not working. If you want to try it, you need very latest CVS version of Dovecot and this patch for Postfix: http://dovecot.org/patches/postfix-dovecot-auth.patch dovecot-auth can be run on it's own (configuration in environment variables), or you can use extra_sockets auth setting which is a ':' separated list of UNIX sockets where to listen in. You'd probably want to set it to /var/spool/postfix/etc/dovecot-auth, the location is hardcoded to /etc/dovecot-auth in the patch for now (smtpd is chrooted). The only real problem is that Dovecot creates the dovecot-auth socket using 0660 root:root modes, so you have to manually chmod it to 0666 or fix owner/group. I guess that needs some more thinking.. Probably each socket should have separate settings for it, but how to do it easily in configuration? .. The patch has also hardcoded dovecot path in Makefile.in, you'll need to change that.

The test for the linux sendfile() function uses ac_compile, no ac_link.

Hi all, Out IMAP client (Outlook and others) use login name like joedirt(a)domainname.com I need dovecot to convert it to joedirt-domainname_com since that is the local login name.

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

[Dovecot] Small change to make dovecot pop3 uw-imap migration friendly
by Oleg I. Vdovikin 01 Jun '04

01 Jun '04

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've made the following change in the code --- dovecot-0.99.10.4.orig/src/pop3/commands.c 2003-05-28 15:17:15.000000000 +0400 +++ dovecot-0.99.10.4/src/pop3/commands.c 2004-05-27 14:06:48.000000000 +0400 @@ -374,7 +374,7 @@ while ((mail = client->mailbox->fetch_next(ctx)) != NULL) { client_send_line(client, message == 0 ? - "%u %u.%u" : "+OK %u %u.%u", + "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, client->uidvalidity, mail->uid); found = TRUE; } and got everything just like in the old uw-imap pop3. I'm current running RH9, but thinking of FC2 which uses dovecot. So, I've rebuild the FC2 rpm for RH9 including this patch. Pop3 users, which do not remove their mails from the server are really happy - they do not receive old mails twice. Probably this small change could be applied to the 1.0, or used as a config option. Any suggestions are greatly appriciated. Thanks, Oleg.

[Dovecot] 1.0-test14
by Timo Sirainen 31 May '04

31 May '04

http://dovecot.org/test/ Maildir syncing is still somewhat broken. I can't really figure out what the problem is. Maybe it's in indexes after all which are just causing bugs in syncing. I think I'll finish implementing mbox syncing and see if same problems appear with it. This release has mostly dovecot-auth changes: - Delay reporting failed authentications - Log IP address of failed authentications (if verbose = yes) - Password schemes can now be loaded from plugins. Example: http://dovecot.org/patches/1.0/password-scheme-lmpass.c - (now that I think of it, auth mechanisms could be implemented as plugins as well if they were placed in password-scheme directory, I think I'll change the directory name so it's more logical) - SASL initial responses are supported (POP3) - SHA/SHA1 password scheme implemented with OpenSSL - dovecot-auth can run as standalone process now (but that doesn't work with Dovecot itself at least yet) - Changes to make it more easier to use it outside Dovecot (eg. the Postfix patch) Added new variables which can be used: %l - local IP address %r - remote IP address %P - PID Added mail_log_prefix setting where variables can be used. So if you want eg. "imap(user,ip-addr,pid): ", set it to "%p(%u,%r,%P): ". And others: - added maildir_stat_dirs setting - several bugfixes for indexes

[Dovecot] Dovecot returns everything starting with "." as folder
by Christoph Hohmann 30 May '04

30 May '04

Hi, I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of LIST "" "%" command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder). This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir. -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/
