[Dovecot] Sieve-Editor
by Andreas Martin 11 May '06

11 May '06

Hi all. I'm looking for an editor for sieve-scripts. I tried the Squirrelmail plugin "avelsieve", but it requires "timsieved", wich Dovecot doesn't use. I don't want my users to write sieve-scripts on the console and server-side-filtering is absolutely required. I know that there are some frontends available, but I can't figure out, which one really works with libsieve and is usable for non-geeks... Do you have any suggestions? Thanks, Andreas

[Dovecot] pop3 problem with small messages with no Subject: and no To: headers
by Ken A 11 May '06

11 May '06

Hello, Seeing a strange thing with dovecot 1.0 b7 pop3. If a user gets a particular _very_ short spam message (not sure what virus makes these..), with NO Subject and NO To: headers and NO body, (example available upon request), the user is unable to download the mail. The log entry is: May 10 10:51:35 mail dovecot: POP3(user): Disconnected top=0/0, retr=1/1344, del=0/75, size=16383381 There's no QUIT, so no "Logged out" disconnect reason. I did a tcpdump to see what was happening. I have not been able to duplicate this myself yet, even with an exact copy of the message that seems to be causing it, so it could be a client issue, but I've never seen this before, and we just switched to Dovecot, so I thought I'd check with the list.. ideas? Message #9 is requested (it's the one in the user's box with missing headers). Dovecot begins returning it, but then disconnects, or so it seems. 10:51:35.171916 IP customer.60181 > mailserver.pop3: P 40:48(8) ack 1633 win 65535 0x0000: 4500 0030 d326 4000 7106 fc20 4624 16a1 E..0.&@.q...F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a93 d845 fe0c .......n~.*..E.. 0x0020: 5018 ffff 3618 0000 5245 5452 2039 0d0a P...6...RETR.9.. 10:51:35.172177 IP mailserver.pop3 > customer.60181: P 1633:2980(1347) ack 48 win 5840 0x0000: 4500 056b ca0b 4000 4006 3101 ceaa 0f11 E..k..@.@.1..... 0x0010: 4624 16a1 006e eb15 d845 fe0c 7ee7 2a9b F$...n...E..~.*. 0x0020: 5018 16d0 3fde 0000 2b4f 4b20 3133 3237 P...?...+OK.1327 0x0030: 206f 6374 6574 730d 0a52 6574 7572 6e2d .octets..Return- 0x0040: 5061 7468 3a20 3c68 7469 3935 6b67 6576 Path:.<hti95kgev 0x0050: 4072 @r 10:51:35.416549 IP mailserver.pop3 > customer.60181: P 1633:2980(1347) ack 48 win 5840 0x0000: 4500 056b ca0d 4000 4006 30ff ceaa 0f11 E..k..@.@.0..... 0x0010: 4624 16a1 006e eb15 d845 fe0c 7ee7 2a9b F$...n...E..~.*. 0x0020: 5018 16d0 3fde 0000 2b4f 4b20 3133 3237 P...?...+OK.1327 0x0030: 206f 6374 6574 730d 0a52 6574 7572 6e2d .octets..Return- 0x0040: 5061 7468 3a20 3c68 7469 3935 6b67 6576 Path:.<hti95kgev 0x0050: 4072 @r 10:51:35.470688 IP customer.60181 > mailserver.pop3: F 48:48(0) ack 2980 win 64188 0x0000: 4500 0028 d329 4000 7106 fc25 4624 16a1 E..(.)@.q..%F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a9b d846 034f .......n~.*..F.O 0x0020: 5011 fabc 09fa 0000 0000 0000 0000 P............. 10:51:35.470997 IP mailserver.pop3 > customer.60181: F 2980:2980(0) ack 49 win 5840 0x0000: 4500 0028 ca0f 4000 4006 3640 ceaa 0f11 E..(..@.@.6@.... 0x0010: 4624 16a1 006e eb15 d846 034f 7ee7 2a9c F$...n...F.O~.*. 0x0020: 5011 16d0 ede5 0000 P....... 10:51:35.515279 IP customer.60181 > mailserver.pop3: . ack 2981 win 64188 0x0000: 4500 0028 d32e 4000 7106 fc20 4624 16a1 E..(..@.q...F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a9c d846 0350 .......n~.*..F.P 0x0020: 5010 fabc 09f9 0000 0000 0000 0000 P.............

[Dovecot] Recommended FS for Dovecot Maildir
by Daniel Watts 10 May '06

10 May '06

Hi, I've heard that for Dovecot/Mailir systems there are filesystems that are optimised for the situation of many small files in one folder. Could I possibly have some feedback on what the recommended filesystems are? I've heard of ReiserFS but was wondering what other options there are and how they compare. If I get a good comprehensive response I'll build a wiki summary page out of the data gathered. Best wishes, Daniel

Our mail system consists of dual exim servers processing incoming mail, writing to maildirs on a home- built NFS system. The home-built system is a dual-xeon machine with lots of SATA disks in a RAID5. We then have two client-facing machines running dovecot and squirrelmail. These are all SuperMicro servers running RedHat ES 4. They all use SATA disks. We are using EXT3 for the RAID5 filesystem, and I have had no performance issues to speak of. I had considered Reiser or xfs, but as I have limited experience with either filesystem I didn't feel comfortable using them in production. -- Roger J.

[Dovecot] Debugging with strace
by Fran Fabrizio 10 May '06

10 May '06

We have a dovecot install that is working fine for everyone except one user, who complains that it takes a minute or longer to delete a single message from the INBOX to Trash. This is happening for him from multiple IMAP clients so it appears to be server-side. I wanted to start up a test instance of dovecot alongside the production one and test there. So I copied dovecot.conf, put imap on port 10143, and started up the test server like this: # strace -tt dovecot -F -c /etc/dovecottest.conf (I could not find the docs for -F but without it dovecot would quickly detatch into a daemon and I could no longer strace it... so is -F for putting dovecot in the foreground like I think? :-) I noticed two things when I did this: 1. My screen just scrolled continuously with poll calls - does dovecot poll something every second even when it has no clients connected? 2. It appeared to interfere with the production install running alongside of it - as I could no longer authenticate to it or copy messages to my Sent folder when I sent something out through the production dovecot. I had to restart the production instance to get it to behave. So my questions are whether all that polling output is normal and also, is my testing method really interfering with the production server, and if so, how to avoid that?

hi, i know this is not really a dovecot-question, but (after searching for hours and hours) here goes : last week i've tested a setup with postfixadmin and dovecot, and i'm very happy with the result! it's running on a FreeBSD-server but i've used this howto (which describes the setup for debian) : http://bliki.rimuhosting.com/space/knowledgebase/linux/mail/postfixadmin+on… big question is : how can i convert the already existing passwords from the mail-users to the mysql-based auth in postfixadmin/dovecot ------------------------------------------ thanks for having dovecot available, it's great to work with ! :) -- grtjs, albi gpg-key: lynx -dump http://scii.nl/~albi/gpg.asc | gpg --import

[Dovecot] managesieve daemon
by Gerald Dachs 10 May '06

10 May '06

Hi, I am currently working on a managesieve daemon, so that I can use the squirrelmail plugin avelsieve together with dovecot-lda. Without this I can't migrate from cyrus to dovecot. For several reasons I don't use the timsieved from cyrus and build it from scratch. Is this interesting for somebody else? Gerald

[Dovecot] Imap folders missing after updating
by Fred Harris 10 May '06

10 May '06

I just updated from 0.99.14 to 1.0beta2 on FC5 and my my IMAP folders have mainly disappeared in my Thunderbird client. All that's left is Inbox and Trash. Is there some configuration setting that's now necessary to make the server think an account uses IMAP folders? The way it seemed to work before was that the presense of a Maildir directory in a user's home indicated IMAP. The new server seems to read the Maildir directory but it doesn't recognize all the folders. Thanks. --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.

[Dovecot] SIEVE: Any information at all?
by Leah Cunningham 09 May '06

09 May '06

Hi, I am quickly losing the will to live over the lack of any kind of information at all about the SIEVE support that is listed in the dovecot features list. Does anyone have any information at all? I've grepped through the source, looked through all the configuration files, and googled a fair bit and come up with nothing at all. How would a user with maildir enable a sieve script? Does it run on port 2000? How can I test functionality? Thanks, Leah

[Dovecot] Encrypted IMAP only from Internet, unencrypted POP3 from internal network
by Rainer Frey 09 May '06

09 May '06

Hi, we have following situation: I migrated our company mailserver from POP3 only to dovecot with IMAP and POP. We need to have unencrypted POP3 from our internal network, and the subnet our mailserver is in. Additionally, we now want to allow encrypted IMAP from the internet (for some defined accounts), preferably with TLS (which means I open Port 143 in our firewall). Now, how can I achieve that they can't use unencrypted plaintext authentication from Internet, while I allow unencrypted POP3 from the mailserver and private network? (I can require using encryption for IMAP from our internal net, but I must have unencrypted POP3 as we use software that retrieves mail via POP3 that doesn't support encryption). My idea was: - use disable_plaintext_auth for IMAP only - use disable_plaintext_auth for internet, but not our networks - allow connection from the internet only for certain accounts, and limit them to use encryption Internet access for POP3 is not necessary. Is any of this possible with dovecot? Or another way to achieve my goal? Non-plaintext authentication is not possible, as we use linux system accounts with shadow passwords.

Hey guys, I just subscribed to the list about 15 minutes ago so i apologize in advance if this is something that has already been discussed. I skimmed through the web archives and I didn't see anything. I'm running FreeBSD/amd64 and after upgrading from 1.0b3 to 1.0b7 I am experiencing the following May 8 13:18:22 loveturtle dovecot: imap-login: Login: user=<turtle>, method=plain, rip=216.89.228.116, lip=216.91.90.11, TLS May 8 13:18:22 loveturtle dovecot: IMAP(turtle): Unrecognized event: kevent {.ident = 2, .filter = 0xfffffffe, .flags = 0x0000, .fflags = 0x00000000, .data = 0x00004000} May 8 13:18:22 loveturtle dovecot: child 32279 (imap) killed with signal 6 Immediately after this imap respawns and then prints this again and crashes. it happens about three or four times a second until i shut down dovecot. I reverted back to 1.0b3 and everything is happy again. Cheers, Dillon

[Dovecot] Problem with "INDEX" in default_mail_env, and pop3
by Andrea Dell'Amico 08 May '06

08 May '06

Hello all, I've a problem with maildir, pop3 and relocated indexes. My configuration is: default_mail_env = maildir:%h/Maildir:INDEX=/var/dovecot/index/% u:CONTROL=/var/dovecot/control/%u I created the "/var/dovecot/{index,control}/%u" directories, each one have rights 700 and the ownership is assigned to the user. When the pop clients connect, they fail with the error dovecot: POP3(<username>): mkdir(/var/dovecot/index/<username>/.INBOX) failed: Permission denied I'm using dovecot 1.0.beta7, authentication is pam. I'm using the following settings, too: valid_chroot_dirs = /home:/var/spool/mail:/var/dovecot/index:/var/dovecot/control (last two directories added when i changed the "default_mail_env" setting). Does anybody know what I'm doing wrong? I need to move indexes in a file system without quota. Thanks in advance, andrea -- "Thinking meat!

[Dovecot] Maildir folder hierarchy question
by Richard Leszczynski 08 May '06

08 May '06

Hello all, I am trying to set up Dovecot to use a particular maildir folder hierarchy and have a problem that relates to the inbox. the folder hierarchy I want in /.../Maildir/ is: .inbox cur new tmp .imap.index.files-for-inbox .sent-items cur new tmp .imap.index.files-for-sent-items however the hierarchy that dovecot gives me is .inbox (unused) .INBOX .imap.index.files-for-.INBOX cur new tmp .sent-items cur new tmp .imap.index.files-for-.sent-items I would like to have the (cur,new,tmp) folders associated with the the .inbox placed in the .inbox directory, not alongside it in the main maildir directory. Dovecot appears to do this automatically for other folders. I'm not too bothered if the .inbox folder has to be capitalised. Is this possible? I suspect from reading the Dovecot Q&A that it may not be as the rootdir has special significance with IMAP but I would like confirmation. I've currently set my default_mail_env as: default_mail_env = maildir:/home/%u/mail/maildir:INBOX=/home/%u/mail/maildir/.inbox which I thought should do accomplish what I want but it has no apparent effect. I'm running SUSE 10.0 with Dovecot 0.99.14-5 (as installed by Yast). KMail and Outlook are being used to access Dovecot. Can anyone help? thank you, Richard L ___________________________________________________________ 24 FIFA World Cup tickets to be won with Yahoo! Mail http://uk.mail.yahoo.com

[Dovecot] CVS forked into development/stable branches
by Timo Sirainen 08 May '06

08 May '06

New branch created to CVS: branch_1_0 It's going to stabilize into v1.0 Dovecot, hopefully somewhat soon. I'll start adding new larger features into HEAD, so you might want to switch to branch_1_0 if you're currently using Dovecot from CVS. You can do this with: cvs up -r branch_1_0 The nightly snapshots are from branch_1_0, at least for now.

Would that be possible? TIA, Geert

hi all i'm trying to rebuild the 1.0 beta 7 src rpm from atrpms.net to use mysql 5, instead of mysql 4 but i'm having issues when it gets to the mysql part of the make i have mysql 5 installed (via mysql.com rpm's) i changed the spec file where it says Buildrequires to say MySQL-devel (instead of mysql-devel) but it always comes back with this error, and i don't know what it means, i also tried leaving it as mysql-devel, but still get the same error when i run rpmbuild -ba dovecot.spec && rpm -Uvh --force ../RPMS/i386/dovecot* am i doing this completely wrong, is there something else i need to do to be able to use mysql 5? /usr/lib/mysql/libmysqlclient.a(sha1.o)(.text+0x60): In function `sha1_result': : multiple definition of `sha1_result' ../lib/liblib.a(sha1.o)(.text+0x8e7):/usr/src/redhat/BUILD/dovecot-1.0.beta7/src/lib/sha1.c:233: first defined here /usr/bin/ld: Warning: size of symbol `sha1_result' changed from 191 in ../lib/liblib.a(sha1.o) to 126 in /usr/lib/mysql/libmysqlclient.a(sha1.o) collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7/src/auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.84952 (%build) thanks dave -- http://dtracorp.com

[Dovecot] Sending email over IMAP?
by Marc Perkel 06 May '06

06 May '06

I'm advocating for a change in the IMAP specification to allow outgoing email to be sent over the same connection as incoming rather that having to separately configure outgoing SMTP email. There are two significant advantages to this concept. 1) It would greatly simplify setup for clients as they would only have to configure one connection rather than two. 2) Spam reduction by authentication. The sending of email over the same connection tells the server that the person who is the sender of the email also has demonstrated they have access to read the account. This would be a powerful whitelisting criteria for eliminating fake senders. So - my question. It seems that it would be easy to do this if there were a standard. Dovecot would merely hand incoming email off to the outgoing SMTP server. Besides the difficulty of getting a standard created, am I right on my assumptions?
