is it possible to run a post-login script in a dovecot proxy with local auth?
by Luca Lesinigo 12 Jul '16

12 Jul '16

We’re using dovecot v2.2.22, authenticating on a local database (passdb with sql driver), and then proxying the connections to the backend server returned by passdb (proxy=y and backend in “host” column). To support some legacy clients we should keep POP/IMAP-before-SMTP running for some time, but right know I don’t know how to hook up a successful authentication in the dovecot proxy. I did read from http://wiki2.dovecot.org/PostLoginScripting: “...it's not currently possible to run post-login scripts in proxies, because they're not actually logging in to the local Dovecot” Does that also holds true even if the proxy is authenticating users locally before proxying them? Failing that, any idea on how to get successful logins, other than parsing the log file? thank you, -- Luca Lesinigo

I don't grok autotools, but I don't think this will solve the problem. If I understand the patch correctly, it modifies the small program used by configure to test a C99 feature. Manually compiling the small test program (with and without the changes made by the patch) will result in a successful compile, but if you compile sha1.h (line 80,81), it will fail. I've reduced the problem to this: void foo(int X[static 20]); will compile but if you remove "X", it won't. Joseph Tam <jtam.home(a)gmail.com>

a question about dovecot-sieve
by 刘莹莹 11 Jul '16

11 Jul '16

question discribe: example: > vim .dovecot.sieve require ["fileinto"]; # rule:[filter1] if anyof (header :contains "Subject" "测试邮件") { fileinto "sieve"; } when i write a mail ,give subject "这是一封测试邮件" , then server convert this subject to " SUBJECT: =?UTF-8?Q?=E8=BF=99=E6=98=AF=E4=B8=80=E5=B0=81=E6=B5=8B=E8=AF=95=E9=82=AE?= =?UTF-8?Q?=E4=BB=B6?= " the essential question is when the mail go through dovecot-sieve plugin, the sieve plugin get mail subject is "这是一封测试邮件" not "这是一封测试邮件"，there is a extra space added(which as segmentation between "=?UTF-8?Q?"). SIMPLY SAY：edit subject"这是一封测试邮件" ——>server convert "SUBJECT: =?UTF-8?Q?=E8=BF=99=E6=98=AF=E4=B8=80=E5=B0=81=E6=B5=8B=E8=AF=95=E9=82=AE?= =?UTF-8?Q?=E4=BB=B6?="——>sieve plugin get "这是一封测试邮件" The result is filter failure. is this a bug ? How can I avoid it？ thanks

Raw backtrace multiple passwords not allowed
by Leon Kyneur 10 Jul '16

Hi Recently enabled support for encrypted passwords on my proxies - CRAM-MD5, DIGEST-MD5, NTLM and APOP to support some new users. Most users are working perfectly though every so often I see this happening in the logs: Jul 09 06:32:51 auth: Error: ldap(user(a)domain.com,192.168.10.90,<mOWiFi431eDKOsBS>): Multiple password values not supported Jul 09 06:32:51 auth: Panic: file passdb-ldap.c: line 99 (ldap_lookup_finish): assertion failed: (password == NULL || scheme != NULL) Jul 09 06:32:51 auth: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x86aae) [0x7ff4db08faae] -> /usr/lib64/dovecot/libdovecot.so.0(+0x86b8e) [0x7ff4db08fb8e] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7ff4db033b5d] -> /usr/lib64/dovecot/auth/libauthdb_ldap.so(+0x720b) [0x7ff4d967a20b] -> /usr/lib64/dovecot/auth/libauthdb_ldap.so(+0x5e2f) [0x7ff4d9678e2f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7ff4db0a338c] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xff) [0x7ff4db0a47ef] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7ff4db0a3415] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7ff4db0a35c8] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7ff4db03a033] -> dovecot/auth [13 wait, 1 passdb, 0 userdb](main+0x39c) [0x7ff4db5454ac] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7ff4da61fb15] -> dovecot/auth [13 wait, 1 passdb, 0 userdb](+0xf6a1) [0x7ff4db5456a1] Jul 09 06:32:51 imap-login: Warning: Auth connection closed with 1 pending requests (max 0 secs, pid=8759, EOF) Jul 09 06:32:51 imap-login: Warning: Auth connection closed with 1 pending requests (max 1 secs, pid=8764, EOF) Password debug shows: Jul 09 06:38:25 auth: Debug: ldap(user(a)domain.com,192.168.10.90,<xSSOKi438ODKOsBS>): Credentials: 4b616e6761733138 Jul 09 06:38:27 auth: Debug: client passdb out: FAIL 2541 user=user(a)domain.com pass=NotPassword original_user=user Jul 09 06:38:37 auth: Debug: passwd-file(tassiedevil,192.168.10.90,<weQKKy438eDKOsBS>): username changed user -> user(a)domain.com Jul 09 06:38:37 auth: Debug: passwd-file(user(a)domain.com,192.168.10.90,<weQKKy438eDKOsBS>): Allowing any password Jul 09 06:38:37 auth: Debug: ldap(user(a)domain.com,192.168.10.90,<weQKKy438eDKOsBS>): pass search: base=o=domains,dc=mail,dc=com scope=subtree filter=(&(objectClass=mail)(status=active)(|(|(mail=user@domain.com)(&(uid=user@domain.com)))(&(enabledService=shadowaddress)(shadowAddress user(a)domain.com)))) fields=mail,userPlaintextPassword,userPlaintextPassword,mailstoreHost Jul 09 06:38:37 auth: Debug: ldap(user(a)domain.com,192.168.10.90,<weQKKy438eDKOsBS>): result: mail=user(a)domain.com userPlaintextPassword=NotPassword; mail,userPlaintextPassword unused Jul 09 06:38:37 auth: Debug: ldap(user(a)domain.com,192.168.10.90,<weQKKy438eDKOsBS>): result: mail=user(a)domain.com userPlaintextPassword=NotPassword; mailstoreHost missing Jul 09 06:38:37 auth: Debug: ldap(user(a)domain.com,192.168.10.90,<weQKKy438eDKOsBS>): PLAIN( Jenni) != 'NotPassword' Jul 09 06:38:39 auth: Debug: client passdb out: FAIL 2826 user=user(a)domain.com original_user=user This particular user has a space in their password.. some other users do not when seeing this error.

Dovecot threading implementation
by Gabriele Bulfon 08 Jul '16

08 Jul '16

Hi, I was trying to compare avrious thread refs/references implementation, both server side and client side. While testing dovecot, it looks to me that issuing thread=references or thread=refs I get the same response, while the refs drafts says it should reverse the date ordering inside a branch. Is this correct? Does Dovecot implements references and refs with same sorting? Also, cyrus has subject grouping included in references (which is bad!). What's dovecot doing in references alg?

> Well, tried with or without patches, but got still same error: > > sha1.h:80: error: static or type qualifiers in abstract declarator For what it's worth, I get the same error compiling on Solaris 10. It may be because I have a rather old gcc (3.4.4). Editing out the "static" keyword from config.h allowed it to finish the compile. Joseph Tam <jtam.home(a)gmail.com>

Deletion of mail from Junk mailbox
by Doug Hardie 08 Jul '16

08 Jul '16

I have a pigeon sive running which directs some of my received mail to the Junk folder. That works just fine. However, a couple minutes later, it is moved to Deleted mailbox and deleted from Junk. At first I thought my client was doing that so I shut down the client and it still happens. Here are the log entries: Jul 2 00:36:31 mail dovecot: imap(doug): copy from INBOX: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:36:31 mail dovecot: imap(doug): delete: box=INBOX, uid=55719, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:39:33 mail dovecot: imap(doug): copy from Junk: box=Deleted Messages, uid=31049, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:39:33 mail dovecot: imap(doug): delete: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:50:29 mail dovecot: imap(doug): expunge: box=Junk, uid=10842, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Jul 2 00:50:29 mail dovecot: imap(doug): expunge: box=INBOX, uid=55719, msgid=<F3C67E609C1A1BC4DB924CEA5FE12C76@ze>, size=3340, from="jnilj" <hr(a)bjwmt.com> Is this the intended way the Junk maibox is supposed to work? I couldn't find any settings that appear to control (or affect) this behavior. — Doug

Released Pigeonhole v0.4.15 for Dovecot v2.2.25.
by Stephan Bosch 08 Jul '16

08 Jul '16

Hello Dovecot users, I have completed the final release. I found a few more problems while testing this release, so a few more fixes are included. I also added a behavioral change to the vacation extension. Changelog v0.4.15: * vacation extension: The sieve_user_email setting is now used in the check for implicit delivery. - imapsieve plugin: For any mail transaction, the mailbox was opened a second time, even if no mailbox rule matched. This was unintentional, useless and caused problems when the imapsieve plugin was used with other plugins like acl. - extprograms plugin: Significantly improved error handling. No stream errors were logged. - extprograms plugin: Fixed bug in handling of result code from remote program (script service). - extprograms plugin: Connection to remote program service was not retried. - Several small fixes based on static analysis. - Fixed handling of quoted string localparts in email addresses. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.15.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.15.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
