[Dovecot] Proposed dovecot update changes in Fedora
by Kenneth Porter 16 Jan '05

FYI, forwarded from the Fedora development list: ------------ Forwarded Message ------------ Date: Saturday, January 15, 2005 7:16 PM -1000 From: Warren Togami <wtogami(a)redhat.com> To: John Dennis <jdennis(a)redhat.com> Cc: Development discussions related to Fedora Core <fedora-devel-list(a)redhat.com> Subject: Proposed dovecot update changes John, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143707 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145214 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145241 Any objections to my proposed changes? I can implement all of this and supply patches for your review, or apply it myself to CVS if you wish. I summarize each problem and my proposed solution below. 1. Unnecessary dependency on mysql/postgresql ============================================= Prereq: postgresql Prereq: mysql These lines are wrong. The package is fine without it, because RPM auto-dep pulls in the client library of mysql and postgresql rather than a larger unnecessary chunk of those databases. These dependencies are resolved properly by yum and handled automatically. Solution: Just remove those lines. 2. dovecot.conf should default to fcntl locking =============================================== https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145214#c7 Our default dovecot.conf changed from fcntl to dotlock sometime after the release of FC2. That is one of the reasons why we see this above bug. This problem must now be attacked on two fronts: 1) Our default dovecot.conf must be changed to use fcntl by default again. If someone uses a broken NFS where fcntl doesn't work, then it is up them to edit their configuration to use dotlocks. If users have not modified dovecot.conf, then upgrading to the new package will set fcntl default. 2) For exisiting users who have modified dovecot.conf, it would be dangerous to force a change to fcntl during %post. Then "mail_extra_groups = mail" is the correct line to add durin 3. FC2 should not link to mysql/postgresql (???) ================================================ https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145241#c1 FC2 dovecot originally did not link to mysql and postgresql, so arguably we should not add those dependencies in an update. Unfortunately our current FC2 update is linked in this way, so we would be breaking existing users if they did begin using this functionality in FC2. I am guessing that the likelihood of this is very low and we should go ahead. (However we could just as easily leave it as is, then it would only be a minor annoyance rather than a real problem.) FC3 dovecot did link to mysql/postgresql libs, so we must not change that or split into sub-packages because then an update would break existing users. FC4 we have the option of splitting mysql/postgresql into sub-packages, which is probably the correct thing to do based on the php precedent. Thoughts?

After running configure and before doing a make, edit config.h: /* Define if you have FreeBSD-compatible sendfile() */ /* #define HAVE_FREEBSD_SENDFILE */ ^^ ^^ Comment out the define for FreeBSD as above and do a make and install.

Note: forwarded message attached. In addition to what I've already posted, the output from gdb when I try to use mutt is: Program received signal SIGABRT, Aborted. 0x18234dcf in kill () from /lib/libc.so.5 And then it dies. __________________________________ Do you Yahoo!?

[Dovecot] istream-limit.c - assertion failed
by Mail Admin 14 Jan '05

14 Jan '05

dovecot: Jan 14 12:25:49 Error: IMAP(xxxuser): file istream-limit.c: line 85 (_seek): assertion failed: (v_offset <= lstream->v_size) That error message is generated when squirrelmail 1.4.4-rc1 attempts to access this peculiar message partially quoted below. It doesn't happen (after copying the message to our testing account) accessing it through squirrelmail now. But it did. The server is running test61 configured --without-pop3d --with-ssl=openssl and --disable-ipv6 and running on FreeBSD 5.2.1. I'm not sure if this bit of a message is useful, but I have seen that error message in dovecot's log more than just this once.

RE: [Dovecot] Strange behavior of mysql 4.1.8/9 + dovecot1.0-test58~test61 on Fedora 3 x86_64 machine
by #LIU QI# 14 Jan '05

Some additional tests. I tried to add a test connection in the main.c under auth, which should be the main file of dovecot-auth. The test connection is done as the first statement in the int main() function. However, it still reports that the connection fails due to access denied. What should I do?? Any suggestions are welcomed. -----Original Message----- From: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] On Behalf Of #LIU QI# Sent: Friday, January 14, 2005 11:41 AM To: dovecot(a)dovecot.org Subject: [Dovecot] Strange behavior of mysql 4.1.8/9 + dovecot1.0-test58~test61 on Fedora 3 x86_64 machine I've built & configured the dovecot to use mysql as the passdb and userdb.

Hello, When I set LDAP auth's search base dn, base dn and filter strings are concatenated. It cause filter cannot match any entries... I fixed it. Please check following patch. p.s.

[Dovecot] maildir and /var/spool/mail
by Steve Hickel 14 Jan '05

14 Jan '05

All, Not sure what to do next. Have imap working in that I can see messages in inbox. When I create a folder it won't create one. Looking at maillog shows that I don't have rights to folder /var/spool/mail/.sent or whatever folder I am trying to create. I have procmailrc and dovecot.conf point to /home/Maildir but for some reason something is tied to /var/spool/mail. Of course I am running FC3 and sendmail. Someone have any ideas as to what to try next? thanks in advance, Steve Hickel -- Steve Hickel <steve(a)korehicom.com> Kore/HiCom Corporation

[Dovecot] REQUEST: Different port(protocol) should be able to use a different certification.
by NAJIMA Hiroki 14 Jan '05

14 Jan '05

Hello, I want to use a different certificate for a different port(protocol). I searched http://wiki.dovecot.org/ and the mail archives. But such mechanism were not found. Could you implement a such mechanism? Or already implemented it, please teach how to do. I am assuming the following situations. MailAddress: [users](a)example.com SMTP Server: smtp.example.com POP3 Server: pop3.example.com IMAP Server: imap.example.com And pop3, imap, smtp are alias of real.example.com When use IMAPS, user connents imap.example.com POP3S, user connents pop3.example.com But one Certification file certificates only one FQDN. For example, dovecot.conf written that protocols = imaps pop3s ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # imap.example.com.cert.pem's CN is imap.example.com In this pattern. MUA such as Thunderbird warn when connect pop3s because FQDN is different. I have an simple idea in this problem. dovecot.conf protocols = imaps pop3s - ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem - ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # certification for imaps + imaps_ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem + imaps_ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # certification for pop3s + pop3s_ssl_cert_file = /etc/ssl/certs/pop3.example.com.cert.pem + pop3s_ssl_key_file = /etc/ssl/private/pop3.example.com.key.pem Dovecot uses imaps_ssl_cert/key whenever MUA connects imaps port, uses pop3s_ssl_cert/key whenever MUA connected dovecot's pop3s port. Could you discuss it? #If it was already discussed, please show pointer(URL) that discussion. Regards. ----- NAJIMA Hiroki

[Dovecot] Virtual users vacation notices and forwards
by Del Stoliker 14 Jan '05

14 Jan '05

I'm in the process of moving from UW-IMAP to dovecot. I'm exploring the idea of using virtual users with dovecot and storing all user information in LDAP. While bouncing this idea off of a coworker, he asked me how we could handle vacation notices and forwards. Currently, we're using a procmail recipe to generate the vacation notice, and the sendmail .forward file for forwards (although most of our forwarding takes place elsewhere so the .forward file is rarely used). These are, of course, dependant on the user having an account on the mail server. How are those of you using virtual users supporting this functionality? Thanks!
