[Dovecot] ioloop-select bug in alpha 4

Howdy, Forgive me if this issue has been more recently addressed in CVS, but a quick scan of the archives didn't turn up any other reports. There appears to be a small typo in src/lib/ioloop-select.c: --- dovecot-1.0.alpha4/src/lib/ioloop-select.c.orig 2005-11-06 22:06:53.000000000 -0800 +++ dovecot-1.0.alpha4/src/lib/ioloop-select.c 2005-11-06 22:07:13.000000000 -0 800 @@ -113,7 +113,7 @@ sizeof(fd_set)); memcpy(&tmp_write_fds, &ioloop->handler_context->write_fds, sizeof(fd_set)); - memcpy(&tmp_except_fds, &ioloop->handler_data->except_fds, + memcpy(&tmp_except_fds, &ioloop->handler_context->except_fds, sizeof(fd_set)); ret = select(ioloop->handler_context->highest_fd + 1, Thanks, Kevin

[Dovecot] Case sensitive nightmare
by Erik Petersen 12 Dec '05

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks

[Dovecot] configuring squirrelmail with tls for both imap & smtp on FC3 with dovecot & postfix

hey friends, I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true. Moreover If I send any mail from squirrelmail there are no entries for ssl or tls in maillogs whereas If I send the mail through evolution I can see tls/ssl entries in maillogs. starting TLS engine Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: setting up TLS connection from [192.168.1.68] Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:before/accept initialization Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello B Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write certificate A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server done A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read client certificate A Dec 12 12:30:08 cluster1 last message repeated 2 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client key exchange A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read certificate verify A Dec 12 12:30:08 cluster1 last message repeated 3 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write change cipher spec A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: TLS connection established from [192.168.1.68]: SSLv3 with cipher RC4-MD5 (128/128 bits) But when I did the config.test for squirrelmail I got the below error Checking IMAP service....

[Dovecot] Corrupted index problem when disk quota exceeded
by Sergey Redin 11 Dec '05

11 Dec '05

Hi! I should report yet another problem with dovecot index files. Suppose we have a user with his filesystem disk quota exceeded. He logins via POP3 or IMAP to remove some mail messages and fix this problem. When he logins for the first time, everything works fine, and he can read and remove something. But if his disk quota is still exceeded when he logs out, he cannot login any more. I guess it is not fair to give user only one chance to clean his mail folders :) The problem is that dovecot tries to rewrite index files on logout, but it cannot do it correctly because the user's filesystem quota is exceeded. So the next time dovecot just replies "Mailbox is in inconsistent state, please relogin". I believe that dovecot should work with any kind of corrupted index files, this is why I report such kind of bugs here. Here is a sample session with dovecot which shows the problem: ======================================== dovtest# telnet localhost pop3 Trying ::1... Trying 127.0.0.1... Connected to localhost.

[Dovecot] Feature request: Dynamic user lookup modules
by Mark Rosenstand 11 Dec '05

11 Dec '05

Hi, As a packager I'd think it would be way cool if the lookup modules that needs to link against external librarires (ldap, pgsql and mysql) could be loaded dynamically at run-time. Am I alone on this? :-)

[Dovecot] openssl > 0.9.f-4 a must for dovecot 0.99.14 ??
by Adrian Mak 10 Dec '05

10 Dec '05

My linux is Redhat AS3 U3, openssl is 0.9.7a-33 I downloaded dovecot 0.99.14 src rpm and rebuild to binary rpm Everything went smooth but I tried to install the dovecot binary rpm, it reported that openssl need >= 0.9.7f-4 Since there are many other rpm packages have dependency on the current version of openssl 0.9.7a-33, so It's not possible to upgrade openssl to 0.9.7f-4 or greater Is it a must to use openssl 0.9.7f-4 or greater in order to use dovecot 0.99.14 ?

[Dovecot] Order of emails
by Marcus Don 10 Dec '05

10 Dec '05

Hi We have an issue regarding the order in which emails are displayed in an imap folder, which our customers regularly complain about. By default, emails are returned from a folder in the order in which they were placed into the folder, which makes perfect sense. However, if an email is moved into another folder, it will always appear at the top, no matter how old it is. We could order the emails ourselves before displaying them in our webmail program. However, this would mean parsing the headers of every single email, which could be many thousands, so would slow things down considerably and greatly increase load. At the moment, we only read 30 at a time as the user pages through the folder. >From what I can see, the order is determined by the timestamp in the email filename, which gets updated every time the email is moved. Is there any way we could disable this, so the filename (or at least the timestamp part of it) remains constant? If so, would this affect in any way the behaviour of other imap clients, such as Outlook? All suggestions welcome.
