[Dovecot] cache questions
by Daniel Watts 06 Aug '07

06 Aug '07

Hi Guys, We have: auth_cache_size = 2048 #Kb auth_cache_ttl = 900 #life of the cache Seems to work well (though haven't tried looking at stats). Only problem is that every so often, one of our new users tries to log in quickly before the account is marked (in a db) as 'active'. They use the right password but the sql query fails because the active flag is not yet set. This results in their trying to log in and failing for 15 minutes (900 seconds) until the cache clears. Is this dovecot caching negative results? Is this a good idea and can it be disabled? Some more questions: 1. Is the expire time on a per-login basis or for the entire cache? If someone logs in 14 minutes after the last expiry is their data cached for just 1 minute? 2. If it is per-login, is the time reset after every hit? If someone is using webmail and hitting the cache every 5 minutes, will the cache keep the information? 3. How does the cache size relate to number of distinct logins? Roughly how many auth datasets cached per 1MB of cache? Thanks! Daniel tg3 dovecot # dovecot --version 1.0.rc27 p.s. please CC my email so I know when this has been replied to. I will respond to group!

[Dovecot] Benchmark: Appending 250k messages
by Timo Sirainen 06 Aug '07

06 Aug '07

I just changed Dovecot v1.1 code to work much more nicely when appending new messages to large mailboxes. Dovecot hg (cydir format, fsync_disable=yes): ./imaptest secs=1 ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2322 1/ 1 0 0 1998 1/ 1 0 0 2293 1/ 1 0 0 2009 1/ 1 0 0 1789 1/ 1 0 0 1245 1/ 1 0 0 43 1/ 1 0 0 32 1/ 1 0 0 881 1/ 1 0 0 2137 1/ 1 .. 0 0 704 1/ 1 0 0 771 1/ 1 0 0 388 1/ 1 0 0 831 1/ 1 0 0 572 1/ 1 0 0 766 1/ 1 Totals: 1 1 251397 Averaging 837/sec. The append speed jumps around quite a lot. Typically it's around 800-1000/sec, but it jumps between 0-500/sec also quite often. I'm not sure why that is. Cyrus v2.3.8 (fsync and fdatasync calls disabled from code): ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2587 1/ 1 0 0 1907 1/ 1 0 0 1597 1/ 1 0 0 1260 1/ 1 0 0 1220 1/ 1 0 0 1151 1/ 1 0 0 1068 1/ 1 .. 0 0 121 1/ 1 0 0 127 1/ 1 0 0 128 1/ 1 0 0 126 1/ 1 Totals: 1 1 79613 Averaging 265/sec. The speed slows down pretty consistently, there's no jumping like with Dovecot.

[Dovecot] Disable IMAP for certain users, but not Webmailer
by FORMER 03 | Baltasar Cevc 06 Aug '07

06 Aug '07

Hi everybody, I'm planning to set up our new mail system using the Dovecot mailbox server. It mostly works fine yet (it's quite straigt forward to set up, I'd say), but there's a thing I haven't been able to find out yet. We provide POP3 access for all users, but want to restrict IMAP access to some of them (because IMAP users tend to leave more messages on the server, thus increasing storage needs). I used to do it by providing two services. One provided the public imap and checked a database flag during authentication, the other just provided IMAP on localhost and did not check the "allowed to use IMAP" flag. What I've found for Dovecot is http://wiki.dovecot.org/Authentication/RestrictAccess While this allows me to provide full POP3 to everybody and in the same time restricting IMAP, I don't see a possibility Is there any possibility to achieve what I need without having two completely separated instances of Dovecot running? I'd appreciate any hints, pointers to documents etc. Thanx, Baltasar -- _____ FORMER 03 GmbH _____ infanteriestra§e 19 haus 6 eg _____ 80797 muenchen _____ baltasar.cevc(a)former03.de _____ www.former03.de _____ fon 089.322112.29 _____ fax 089.322112.11 _____ mobil 0178.691.2233 _____ geschftsfhrer _____ sebastian fiedler _____ gert zellentin _____ handelsregister _____ HRB Mnchen 148468 _____ steuer _____ ust.-id DE 2291076876

[Dovecot] dovecot.index.cache weirdness
by Tan Shao Yi 06 Aug '07

06 Aug '07

Hi Timo, Just a quick check, may I know if the following output of idxview is normal? (see bottom of e-mail) I am running dovecot-1.0.3 on a Solaris 10 SPARC box. Deleting dovecot.index.cache does not seem to help for this user; it keeps getting regenerated with these same lines. I seems that I have to set mmap_disable=yes on this box to have a "clean-looking" dovecot.index.cache. Is it mmap related? Or it just happens to be a coincidence? Cheers, Tan Shao Yi /usr/local/libexec/dovecot/idxview dovecot.index dovecot.index.cache (... normal looking stuff ...)

[Dovecot] Some of my IMAP Folders vanished in some MUAs
by Dominik Schulz 05 Aug '07

05 Aug '07

Hi, I'm using dovecot for some time now. Previously I was using Courier and I've migrated this setup to dovecot which went pretty fine. Now I'm experiencing some strange behaviour when using some newer mail clients. Some of my Folders, like "spam", are vanished. The strange point is that it only happens in some clients, like Thunderbird 2.x+ or KMail 3.5.x. In others, like Thunderbird < 2, Mutt or my Webmailer (Horde) they still show up. These folders are still there, i.e. in the filesystem, and the permissions seem to match those of the other folders which can be seem in all MUAs. I don't know if this is even related to dovecot but I think this is where I should start looking for an solution. I'm using dovecot 1.0.rc15 from Debian (stable/etch). It'd be great if anyone was able to help me. Thanks in advance. Best Regrads Dominik Schulz

[Dovecot] Password Encryption
by Dave Morrow 05 Aug '07

05 Aug '07

Hi all. I hope this is not a RTFM-type question, but I've been unable to find a searchable archive of this mailing list....... I recently began investigating using Dovecot/Postfix/MySQL solution. I've been following the documentation http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?highlight=%28m ysql%29 While everything seems to have gone right, I have been unable to successfully login to the IMAP server using Outlook Express. It seems that the problem may relate to PostfixAdmin storing passwords in the mysql database md5 encrypted, and Dovecot is not able to read them, but I am not certain. The error when a client logs in is something like dovecot: auth-worker(default): plain_md5_verify(testuser1(a)mydomain.com): Invalid password encoding David Morrow Technical Systems Lead Autodata Solutions Company David.Morrow(a)Autodata.net <mailto:David.Morrow@Autodata.net> http://www.autodatasolutions.com <http://www.autodatasolutions.com/> Tel: (519) 963-3020 Fax: (519) 451-6615 Think slowly.

by Reinhard Hainz 05 Aug '07

05 Aug '07

hi, is it possible to modify the mail-header (subject) within the deliver process (maybe by a lda-plugin)? I have tried to write a simple plugin for this, but I cannot find a way to modify the mail befor writing it to the mailbox.

[Dovecot] IMAP-Proxy and LDAP?
by Patrick Ben Koetter 05 Aug '07

05 Aug '07

I am doing some research on Dovecots IMAP-Proxy features mentioned in <http://wiki.dovecot.org/HowTo/ImapProxy> and <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy>. The docs only mention SQL as backend to hold required data. Is it also possible to use LDAP?

[Dovecot] sendfile on Solaris 10 SPARC?
by Tan Shao Yi 04 Aug '07

04 Aug '07

Hi, I am using dovecot-1.0.2 and am observing occassions where the imap process for the user goes into an infinite loop. A truss of the process gives: pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4) Err#11 EAGAIN pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4) Err#11 EAGAIN pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 (... repeatedly ...) When I searched the maillog for the user, the last actions taken were: dovecot: Aug 04 10:50:42 Info: imap-login: Login: user=<XXX>, method=PLAI N, rip=203.120.90.32, lip=203.120.90.85 dovecot: Aug 04 10:50:42 Info: IMAP(XXX): copy -> Trash: uid=25, msgid=<d 05001c7d51a$0a18c550$958f3011@burgaldceo> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): copy -> Trash: uid=26, msgid=<4 14901c7d5bd$55a80b40$26227a4d@Mitchell> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): copy -> Trash: uid=27, msgid=<9 31601908.49031521463794(a)lanecompany.com> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): deleted: uid=25, msgid=<d05001c 7d51a$0a18c550$958f3011@burgaldceo> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): deleted: uid=26, msgid=<414901c 7d5bd$55a80b40$26227a4d@Mitchell> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): deleted: uid=27, msgid=<9316019 08.49031521463794(a)lanecompany.com> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): expunged: uid=25, msgid=<d05001 c7d51a$0a18c550$958f3011@burgaldceo> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): expunged: uid=26, msgid=<414901 c7d5bd$55a80b40$26227a4d@Mitchell> dovecot: Aug 04 10:50:42 Info: IMAP(XXX): expunged: uid=27, msgid=<931601 908.49031521463794(a)lanecompany.com> dovecot: Aug 04 10:50:43 Info: IMAP(XXX): Disconnected: Logged out May I know what could have caused the problem or is there any other information I can provide?

Re: [Dovecot] Dovecot strong or not for a big Webmail architecture

Yep... and we have 500K very active users on it. We've scaled Dovecot horizontally without NFS, just lots of independent Dovecot server intances with smart proxy/mail-routing infrastructure around it. It can easily scale to millions of users this way. Just make sure you throw enough disks at it and you'll be fine, with or without NFS. > Do you think it's a good solution to use one synchronised local Openldap on each > server Dovecot ? No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. > Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. > Are cyrus or courrier-imap better solutions ? Definitely not courier-imap, because of it's lack of indexes. Not sure about Cyrus. > Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy > in this architecture, is Dovecot scalable ? My opinion is Zimbra is too heavy beccause of the way mail is stored on the backend. Dovecot with maildir scales out well, and the promise of dbox mail storage format appears that it will make it even more scalable down the road. Bill

[Dovecot] MD5 mis-match
by Big Pizzle 03 Aug '07

03 Aug '07

Hi all, I'm almost finished building our new load balanced email server that are attached to an NFS mountpoint. There are currently two e-mail servers connected to the NFS share. Both email servers are running CentOS 4.5 with Postfix 2.4.3, Dovecot 0.99, and authenticating via LDAP. Dovecot is using Maildir format. I've been trying to do some benchmarks using Postal and Rabid, and whenever I run rabid, I'm getting errors like this: MD5 mis-match, calculated:a628289996ce19910ebbd4eef2ebc3fc, expected 9406a7cf56afb5a1308eb5377e141719! However, when I tail the /var/log/maillog, I don't see errors - I just see the pop3-login. Just wondering if that is okay. I've also been trying to find an RPM for Dovecot 1.0.3, with no avail. Anyone know where I can get one? Thanks in advance. Patrick

At least UW-IMAP also does that.. Or at least make relaxing it an option in v1.1. I personally think it should be relaxed. Bill

[Dovecot] Looking for RPM for 1.0.3 for CentOS with imap, ldap, and ssl
by Big Pizzle 03 Aug '07

03 Aug '07

Hi, I don't know how to compile Dovecot from src rpm;s - in fact I tried and failed miserably. The only other src rpm I have ever built was postfix, and I ran into a whole bunch of errors trying to build an rpm from the src rpm at ATRpm. Anywho, I was wondering if one of you wonderful Dovecot members would be willing to create an RPM for CentOS 4.5 that includes ldap and ssl. Or, if someone knows of a URL I can go to and follow a Dovecot-related src rpm build tutorial, that would be of great help too. Heck - I'll even settle for a 1.0.2. Since Dovecot doesn't support 0.99 I want to make sure I have the most recent package. Thanks in advance. Patrick

[Dovecot] Dovecot strong or not for a big Webmail architecture
by John fistack 03 Aug '07

03 Aug '07

Hello, Do you think Dovecot could handle millions of active users in a big architecture ? This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) : - 40 Dovecot servers - 4 LVS - 20 Apache+PHP - 2 Openldap - 20 Postfix + ClamAV + SpamAssassin - 1 NFS Netapps For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I want to work in NFS. I've experimented problem with Cyrus and NFS on Netapp. I want to use maildir, I can manage limitations of inodes with Netapp. I know webmail.us use Dovecot, what is the most big dovecot architecture known ? Do you think Dovecot can handle 1 million of active users in a good architecture ? Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? Do you think It's possible to use Postgresql or MySQL instead of Openldap ? Are cyrus or courrier-imap better solutions ? Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy in this architecture, is Dovecot scalable ? Thank you for your ideas. Regards.

[Dovecot] dovecot 1.0.2, sieve 1.0.2 and regex
by Alexander Hoogerhuis 03 Aug '07

03 Aug '07

I've just ported a largeish procmail script across to sieve and want to get to use wildcards in filing mail and can't seem to get regex to work. The script starts nicely with: > require ["fileinto","regex","envelope","vacation","regex"]; and a bit down these few lines comes into play: > elsif header :regex "From" "logwatch.*stuff.com" { > fileinto "INBOX.Admin/Logwatch Stuff"; > } and regex just never seem to catch. I have 50ish machines in the stuff.com domain, and writing an induvidual section like this works: > elsif header :contains "From" "logwatch(a)a.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } > elsif header :contains "From" "logwatch(a)b.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } etc. But this shouldn't be neccesary? mvh, A

Hello list, my name is Steven and of course: I got a problem... we are using dovecot 0.99 because it´s the actual stable version for RedHat 4 Enterprise. I am trying to authenticate using "PLAIN" but I don´t know how. that´s what I am doing: telnet conny.MYDOMAIN.de 143 Trying IP.AD.RE.SS... Connected to conny.MYDOMAIN.de. Escape character is '^]'. * OK dovecot ready. a1 authenticate plain + a1 NO Authentication failed. what do I have to send after receiving the "+"-symbol? dovecot is waiting for something base64-encoded and I tried to give him by typing my username and pass and encrypted it here : http://www.php-einfach.de/base64_generator.php But I don´t know the correct syntax and it drives me crazy.... thanks for ANY help Steve .

Is there a way to setup the sieve plugin so a user can create his own rules? sort of like ~/.procmailrc TIA jalal

[Dovecot] v1.0.3 released
by Timo Sirainen 02 Aug '07

02 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

Probably something like this, although I haven't tried it... src/lib-mail/message-parser.c @225: - if (!hdr->eoh && strcasecmp(hdr->name, "Mime-Version") == 0) { + //if (!hdr->eoh && strcasecmp(hdr->name, "Mime-Version") == 0) { /* it's MIME.
