[Dovecot] Auto-blacklisting hosts after too many failed logins
by Amon Ott 29 Aug '06

29 Aug '06

Hi folks, first of all thanks for Dovecot, I appreciate it a lot. On one of our servers, we experience regular tries to brute force logins, probably based on harvested mail addresses. Now I wonder if dovecot has or could in future have some mechanism to blacklist remote IP addresses after a configurable number of failures to login to any account. Blacklisted IPs could simply be disconnected without giving them a chance to do anything. After e.g. one day or one hour of no further connection, the blacklist entry could be dropped. As a bonus, it would be great to have a way to close the POP3/IMAP firewall ports to these IPs to avoid dovecot seeing the connection at all. A kind of blacklist status file on disk would be enough, from which some cron job could fill a firewall chain. If necessary, I would try to add this functionality myself.

[Dovecot] 1.0rc7 working well
by Bruce Lane 29 Aug '06

29 Aug '06

Fellow dove-users, Just a note to say that Dovecot 1.0rc7 is working very well indeed, supplying SPOP3, regular POP3, and TLS/SASL services on FreeBSD 6.1 Production, in conjunction with Postfix 2.3.2. I have authentication methods PAM and passwd in use. Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] dovecot-1.0_rc7 crashes (Login process died too early) with repeated deletes from thunderbird
by Tim Schafer 28 Aug '06

28 Aug '06

I can consistently reproduce a crash in dovecot: Select 20 or more messages and copy them to a test folder. Go into that test folder and SHIFT-DEL the messages rapidly (holding down SHIFT-DEL works best) Just rapidly DELing them (even holding down DEL) doesn't do it (unless it's the Trash folder) I'm using the following namespace (in case that's relevant) namespace private { separator = . prefix = INBOX. inbox = yes } The /var/log/syslog for the session reads: Aug 24 14:58:54 hostname dovecot: Dovecot v1.0.rc7 starting up Aug 24 14:58:55 hostname slapd[7243]: conn=147 fd=9 ACCEPT from IP=127.0.0.1:41074 (IP=0.0.0.0:389) Aug 24 14:58:55 hostname slapd[7243]: conn=147 op=0 BIND dn="" method=128 Aug 24 14:58:55 hostname slapd[7243]: conn=147 op=0 RESULT tag=97 err=0 text= Aug 24 14:59:09 hostname dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Ilip=192.168.0.7^Irip=192.168.0.100 Aug 24 14:59:09 hostname dovecot: auth(default): client out: CONT^I1^I Aug 24 14:59:09 hostname dovecot: auth(default): client in: CONT^I1^IAHRdfmkerjejfkdeie Aug 24 14:59:09 hostname dovecot: auth(default): client out: OK^I1^Iuser=username Aug 24 14:59:09 hostname dovecot: auth(default): master in: REQUEST^I1^I10081^I1 Aug 24 14:59:09 hostname dovecot: auth(default): master out: USER^I1^Iusername^Isystem_user=username^Iuid=1000^Igid=100^Ihome=/home/username Aug 24 14:59:09 hostname dovecot: imap-login: Login: user=<username>, method=plain, rip=192.168.0.100, lip=192.168.0.7 Aug 24 14:59:10 hostname dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Ilip=192.168.0.7^Irip=192.168.0.100 Aug 24 14:59:10 hostname dovecot: auth(default): client out: CONT^I1^I Aug 24 14:59:10 hostname dovecot: auth(default): client in: CONT^I1^IAHRdfmkerjejfkdeie Aug 24 14:59:10 hostname dovecot: auth(default): client out: OK^I1^Iuser=username Aug 24 14:59:10 hostname dovecot: auth(default): master in: REQUEST^I2^I10082^I1 Aug 24 14:59:10 hostname dovecot: auth(default): master out: USER^I2^Iusername^Isystem_user=username^Iuid=1000^Igid=100^Ihome=/home/username Aug 24 14:59:10 hostname dovecot: imap-login: Login: user=<username>, method=plain, rip=192.168.0.100, lip=192.168.0.7 Aug 24 14:59:12 hostname dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Ilip=192.168.0.7^Irip=192.168.0.100 Aug 24 14:59:12 hostname dovecot: auth(default): client out: CONT^I1^I Aug 24 14:59:12 hostname dovecot: auth(default): client in: CONT^I1^IAHRdfmkerjejfkdeie Aug 24 14:59:12 hostname dovecot: auth(default): client out: OK^I1^Iuser=username Aug 24 14:59:12 hostname dovecot: auth(default): master in: REQUEST^I3^I10085^I1 Aug 24 14:59:12 hostname dovecot: auth(default): master out: USER^I3^Iusername^Isystem_user=username^Iuid=1000^Igid=100^Ihome=/home/username Aug 24 14:59:12 hostname dovecot: imap-login: Login: user=<username>, method=plain, rip=192.168.0.100, lip=192.168.0.7 Aug 24 14:59:14 hostname dovecot: IMAP(username): Disconnected Aug 24 14:59:14 hostname dovecot: imap-login: Disconnected: rip=192.168.0.100, lip=192.168.0.7 Aug 24 14:59:14 hostname last message repeated 2 times Aug 24 14:59:14 hostname dovecot: Login process died too early - shutting down Aug 24 14:59:14 hostname dovecot: imap-login: Disconnected: rip=192.168.0.100, lip=192.168.0.7 Aug 24 14:59:14 hostname slapd[7243]: conn=147 op=1 UNBIND Aug 24 14:59:14 hostname slapd[7243]: conn=147 fd=9 closed -- Regards, Tim Schafer

[Dovecot] Reproduced the Login process died too early issue.
by Johnny Vestergaard 28 Aug '06

Hi. I tried for some time to reproduce the "Login process died too early issue". It seems related to when the system run out of file descriptors, to force the issue i forwarded 3k of messages trough the server(using thunderbird).

Well, I finally got around to fiddling with this, and I now have created a /etc/pam.d/system-auth that doesn't trigger the annoying authentication failure messages in syslog. The file is shown below. I've tested this by connecting in using SSH (setup for PAM) both as a user in the local /etc/passwd and as a user in LDAP. Also, I tested /etc/passwd users with the LDAP server stopped, and that worked too. Finally, I tested connecting to Dovecot as an LDAP user. Note: The only section that references LDAP is the auth section. That's because account and session rely on pam_unix to pick up the information using nss_ldap (i.e. /etc/nsswitch.conf says "files ldap" for passwd, group, etc.) This seems to work for me... Also, note that my LDAP server stores Samba passwords too, so that's why the password section uses pam_smbpass (which in turn is setup to access LDAP via /etc/samba/smb.conf) rather than pam_ldap. This is so both the Unix and SMB passwords are updated in LDAP. Anyway, here's my file. Anyone want to pick holes in it? Indented lines are just mail formatting... #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required /lib/security/$ISA/pam_env.so auth sufficient /lib/security/$ISA/pam_ldap.so debug auth sufficient /lib/security/$ISA/pam_unix.so use_first_pass likeauth auth required /lib/security/$ISA/pam_deny.so account required /lib/security/$ISA/pam_unix.so account sufficient /lib/security/$ISA/pam_succeed_if.so uid < 100 quiet account required /lib/security/$ISA/pam_permit.so password requisite /lib/security/$ISA/pam_cracklib.so retry=3 password sufficient /lib/security/$ISA/pam_smbpass.so use_authtok password sufficient /lib/security/$ISA/pam_unix.so nullok use_authtok md5 shadow password required /lib/security/$ISA/pam_deny.so session required /lib/security/$ISA/pam_limits.so session required /lib/security/$ISA/pam_unix.so session required /lib/security/$ISA/pam_mkhomedir.so skel=/etc/skel/ umask=0077

[Dovecot] failed to start

Hello, i saw you posted on dovecot.org and was hoping you could assist with a problem i have with dovecot. I installed the attached file to webmin and clicked it said it installed correctly: Dovecot IMAP/POP3 Server in /usr/libexec/webmin/dovecot (372 kB) under category Servers I clicked the link and then clicked "Start Dovecot Server" from the webmin panel and got this error: Failed to start Dovecot : I assume this means a file is missing. My config file looks like this: dovecot=/usr/sbin/dovecot dovecot_config=/etc/dovecot.conf init_script=dovecot pid_file=/var/run/dovecot/master.pid There doesn't appear to be a dovecot directory in: etc/rc.d/init.d/ Perhaps that's the issue? I'm running Redhat Linux 4. Can you assist in any way? Any help is most appreciated. Thanks, Don

[Dovecot] imap service not working
by LeVA 26 Aug '06

26 Aug '06

Hi! I'm using dovecot-1.0.rc7 with pop3 and imap. The pop3 is ok, really, no problem at all. With imap, I have the following problem: From the client side it looks like it logs in - logs out - logs in - logs out... can not see any emails or directories. From the server side, I can see these in the logs: dovecot: Aug 26 22:29:00 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=x.x.x.x rip=x.x.x.x dovecot: Aug 26 22:29:00 Info: auth(default): client out: CONT 1 dovecot: Aug 26 22:29:00 Info: auth(default): client in: CONT 1 AHRlc3p0AGxvZmFzeg== dovecot: Aug 26 22:29:00 Info: auth(default): client out: OK 1 user=teszt MAIL=maildir:/ dovecot: Aug 26 22:29:00 Info: auth(default): master in: REQUEST 30 15660 1 dovecot: Aug 26 22:29:00 Info: auth(default): master out: USER 30 teszt uid=8010 gid=8010 home=/var/mail/virtual/teszt/Maildir/./ dovecot: Aug 26 22:29:00 Info: IMAP(teszt): Effective uid=8010, gid=8010 dovecot: Aug 26 22:29:00 Info: IMAP(teszt): maildir: data=/ dovecot: Aug 26 22:29:00 Info: IMAP(teszt): maildir: root=, index=, control=, inbox= dovecot: Aug 26 22:29:00 Info: imap-login: Login: user=<teszt>, method=plain, rip=x.x.x.x, lip=x.x.x.x, TLS These messages are repeating, but with an incrementing number: "USER 30 teszt". This number after the 'USER' word increments with every login. The user's mail directory has 770 perms, and owned by 8010:8010 (the teszt user's UID and GID). The cur/new/tmp folders gets created, but nothing more. The MTA on the server puts the messages inside the new/ folder, and I can get the mails with pop3 from the 'teszt' account. Only imap is acting funny. This "infinite loop" happens with Thunderbird, but I tried it with KMail too. The latter says right after the login procedure: "The connection to the server IMAP Account was unexpectedly closed or timed out. It will be re-established automatically if possible." Is there some script which makes the maildir folder "ready" for use (like the mkmaildir with courier imap), or is there some special file which I must put in it to make it work? Thanks for the help!

[Dovecot] separate passdb for imap and pop3
by LeVA 26 Aug '06

26 Aug '06

Hi! Is this possible? I couldn't find any writings about the 'auth' (like 'auth default') keyword in the wiki. What does that mean? Can I setup seperate user and password dbs for sepearate circumstances? I've tried to experiment with it and added two auths: auth pop3 { mechanisms = plain digest-md5 passdb passwd-file { args = /etc/dovecot_pop3.passwd } userdb passwd-file { args = /etc/dovecot_pop3.passwd } user = _dv_auth } auth imap { mechanisms = plain digest-md5 passdb passwd-file { args = /etc/dovecot_imap.passwd } userdb passwd-file { args = /etc/dovecot_imap.passwd } user = _dv_auth } But how can I configure dovecot to use the 'auth imap' for imap authentications, and use 'auth pop3' for pop3 authentications. With the above setup dovecot always try to use the last one (auth imap). Any help would be appreciated! Thanks! Daniel -- LeVA

[Dovecot] Dovecot SSL issue on Solaris 10 x64 (64-bit)
by Patric 26 Aug '06

26 Aug '06

I'm having an issue with Thunderbird (and Opera) and Dovecot SSL on a Solaris 10. My OS is Solaris 10 6/06 x86 (running in 64-bit mode) using ZFS (disk mirror) as the filesystem for my users. Dovecot version is 1.0rc7 (logs below are from 1.0rc6). First the connection asks if the SSL-certificate should be accepted, accepting it seems to work but then nothing happens. Thunderbird is quite silent, not always displays an error message, it just seems that there are no emails to download. It works fine in Mac OS X Mail.app with POP3s and IMAPs (both SSL). But not for Thunderbird (1.5.0.5) and Opera (latest). Setting "verbose_ssl=yes" and "auth_debug=yes" in the configuration gives this error from a Thunderbird login: Aug 16 14:16:28 credo dovecot: [ID 107833 mail.warning] pop3-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [85.225.200.123] Aug 16 14:16:28 credo dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=85.225.200.123, lip=195.198.174.212, TLS Aug 16 14:16:29 credo dovecot: [ID 107833 mail.warning] pop3-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [85.225.200.123] Aug 16 14:16:29 credo dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=85.225.200.123, lip=195.198.174.212, TLS It seems to be that the OpenSSL installed with Solaris 10 is abit "broken" or missing the cryptographic procotols needed. (at least from what I've read on the Internet) Strange that it works fine with Mail.app on Mac OS X. So, I installed the latest OpenSSL, compiled, tested and installed. (no problems occured) Back to compiling Dovecot, used this oneliner to point it to the new OpenSSL (and my compile settings): env PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig ./configure --sysconfdir=/usr/local/etc --with-ssldir=/usr/local/etc/ssl Worked! bash-3.00$ egrep "^SSL_" config.log SSL_CFLAGS='-I/usr/local/ssl/include ' SSL_LIBS='-L/usr/local/ssl/lib -lssl -lcrypto -lsocket -lnsl -ldl ' But gives this error message when I compile: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/usr/local/ssl/include -o ssl-build-param ssl-init-main.o ssl-init-openssl.o ssl-init-gnutls.o ../lib/liblib.a -L/usr/local/ssl/lib -lssl -lcrypto -ldl -lsocket -lnsl -lrt -lsendfile ld: warning: file /usr/local/ssl/lib/libcrypto.a(dh_asn1.o): wrong ELF class: ELFCLASS64 Undefined first referenced symbol in file DH_generate_parameters ssl-init-openssl.o ERR_get_error ssl-init-openssl.o ERR_error_string_n ssl-init-openssl.o i2d_DHparams ssl-init-openssl.o ld: fatal: Symbol referencing errors.

If I restart thunderbird, then all goes well for a couple of minutes. I need to solve this problem. I already had a system crash that was probably caused by the cpu heat. Pleas help me. Laszlo

[Dovecot] Restricting IP and/or user access (POP3/IMAP)
by Phil Clare 25 Aug '06

25 Aug '06

Hi, The documentation says to authenticate only from a specific IP or network… if you set this to 127.0.0.1 to indicate the local loop then this effectively blocks every IP address but this one. Since the extra field is in passdb then this would imply it can be done on a per user basis. Have you tried this?

[Dovecot] multiple mailboxes in imap
by einKI.ml 25 Aug '06

25 Aug '06

Hi I try to setup a mail server which fetches mails from some pop accounts and presents them through imap (with dovecot) to my local network. I get the mails with getmail at this works as it should. To use dovecot as a pop3 and imap server works too. Now I am trying to setup multiple mailboxes which then should be presented to the user as different folders. I think I have to use namespaces for this (is this correct?) So I tried to configure two namespaces with the following statement. namespace private { separator = / inbox = yes prefix = } namespace private { separator = / prefix = ns location = maildir:/data/server/mail/in/%u/ns } when i try to access the imap server with thunderbird I can receive mails for Inbox but when I want to subscripe an additional folder ns can be seen but is grayed out in thunderbird. To summarize this can anybody give me a hint or example how to configure multiple mailboxes which are located in different directories on the server. thx

[Dovecot] forward flag metadata
by Tim Schafer 24 Aug '06

24 Aug '06

In testing the migration from courier-imap to dovecot I've discovered that the forward flag on messages isn't kept track of in a standard way. courier-imap seems to keep track of forwarded messages in courierimapkeywords/:list dovecot seems to add an 'a' flag to the filename. Unfortunately this 'a' flag information doesn't seem to be given out by dovecot. It's like it's write only. Is it a bug that dovecot doesn't hand out the "forwarded" metadata? -- Regards, Tim Schafer Information Technology Logistics Easier with Technology Freight Solution Providers direct 916-376-6190 10453 Old Placerville Road fax 916-376-6156 Sacramento, CA 95827 tim_schafer(a)shipfsp.com

[Dovecot] getting dovecot unwedged
by Scott Murman 24 Aug '06

24 Aug '06

I'm having a problem with the dovecot server. I've upgraded to 1.0rc7 to no avail. My naive view is that a cache file is corrupt, or a lock file cannot be unset. Certain mailboxes cannot be accessed to read or write. Checking the process, the server looks stuck in an infinite poll/wait loop. telnetting directly to the server shows that things are definately amiss, though the original problem may have been caused by a faulty client (Apple Mail or Outlook). My question at this point is how to unwedge the server. Is there a cache repair utility, or a list of files which shouldn't exist? I don't see this info on the Wiki. After sortinig this out, I'm going to install mysql, since this seems to be the more-tested installation. Will dovecot automatically rebuild my current databases or do i need to prepare for sql by hand? -SM-

[Dovecot] dovecot v1.0 rc7 hung up
by Jack Chen 24 Aug '06

24 Aug '06

It looks like the v.0 RC7 is still not stable. It hangs almost every day. This morning I found that pop3 was not working but imap was working. I know other times when dovecot stop working, neither pop3 and imap worked. I just want to know if other users are getting the same problem.

[Dovecot] (no subject)
by Joseph D. Wagner 24 Aug '06

24 Aug '06

Ok, I tried: sh -x /etc/rc.d/init.d/dovecot start and it started ok. Then I tried: sh /etc/rc.d/init.d/dovecot start and it started ok too. However, simply using: /etc/rc.d/init.d/dovecot start won't start. On a hunch, I disabled SELinux, and then: /etc/rc.d/init.d/dovecot start started ok. So I have an SELinux problem. Right now I'm doing a filesystem relabel. If that doesn't work, does anyone know where to go from here? Joseph D. Wagner

[Dovecot] Problems with dovecot 1.0rc5 + MySQL 5.0.24
by Daniel Torreblanca 24 Aug '06

24 Aug '06

Hi all, I'm having an intermittent problem logging users in through a webmail client (RoundCube). My maillog reports this: auth(default): vmysql: sql error[3]: MySQL server has gone away imap-login: Disconnected: user=<sales(a)coppersinkdepot.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured The MySQL server hasn't gone anywhere, I can log into it fine and other apps report no problems with it. Restarting Dovecot fixes this issue, but it'll just happen again later. I'm on OpenBSD 3.9 using vpopmail. I've looked through the mailing list archives but can't find any info on this specific problem. Any ideas?

Re: [Dovecot] 0.99.14-1.1.el3 vs 1.0-0_20.rc7.el3

I am sorry maybe I confused all of you, but I am not running them side by side. What I did was install one rpm and uninstall it then install 1.0 and then uninstall it. Testing the individually when installed.

[Dovecot] Rename folder bug dovecot-1.0RC6 ?
by Ian Thurlbeck 23 Aug '06

23 Aug '06

Dear All can someone confirm this bug please ? I am using Thunderbird 1.07, TB 1.5.0.4, Horde/IMP webmail as test clients, all running on FC4. Server is 1.0RC6 on CentOS 4 with maildir-sep set to ';' To reproduce: In your favourite mail client: 1. Create a top-level mail folder "atest" 2. Rename "atest" to "atest-extra" (basically hyphen<anything>) Result: Error about mailbox "atest-extra" does not exist If you refresh the folder list you see a new folder called "atest-extra-extra" (read all about it). Anyone else see this or is just me ?
