[Dovecot] Bug in dovecot 1.2 dict
by Sascha Wilde 06 Oct '08

06 Oct '08

Hi Timo, Hi *, in 1.2 the dict server (tested with sqlite backend) is somewhat broken. It bails out regularly with "Fatal: dict: Socket already exists: ..." (looks like a race condition as it doesn't fail always). We discovered that this new code in dict-server.c seems to be the problem: server->fd = net_listen_unix_unlink_stale(path, 64); if (server->fd == -1) { if (errno == EADDRINUSE) i_fatal("Socket already exists: %s", path); else i_fatal("net_listen_unix(%s) failed: %m", path); } replacing it with the old code: int i = 0; [...] while (server->fd == -1) { server->fd = net_listen_unix(path, 64); if (server->fd != -1) break; if (errno != EADDRINUSE || ++i == 2) i_fatal("net_listen_unix(%s) failed: %m", path); /* see if it really exists */ if (net_connect_unix(path) != -1 || errno != ECONNREFUSED) i_fatal("Socket already exists: %s", path); /* delete and try again */ if (unlink(path) < 0) i_fatal("unlink(%s) failed: %m", path); } "fixes" the problem. But I think the real fix would have to be done in the new function `net_listen_unix_unlink_stale'. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 Intevation GmbH, Osnabrück http://www.intevation.de/~wilde/ Amtsgericht Osnabrück, HR B 18998 http://www.intevation.de/ Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] FETCH for mailbox mailboxname UID #1 got too little data: #2 vs #3
by Diego Liziero 05 Oct '08

05 Oct '08

I got it with multiple imaptest instances even with current dovecot-1.1 hg tree. I checked the emails with that UIDs and they are actually truncated. Some things I noted on these mails: - they are all with MIME multipart attachments. - the last multipart attachment is truncated - the truncated last line is not complete - the following line is the beginning of a new mail (From line) without any empty line after the truncated attachment. - in "got too little data: #2 vs #3" 0 <= #2 < #3 (zero included) - Content-Length: #4 is sometimes bigger than both #2 and #3, sometimes smaller. Regards, Diego.

[Dovecot] How to bypass checking of system users by virtual users?
by Dâniel Fraga 05 Oct '08

05 Oct '08

Hi, I have one real domain (abusar.org) and the others are virtual. So I configured dovecot.conf as the following: # for abusar.org, real domain mail_location = mbox:~/.mail/:INBOX=/var/mail/%n # for the remaining virtual domains userdb static { args = uid=17 gid=17 home=/var/spool/virtual/%d/.home/%n mail=mbox:/var/spool/virtual/%d/home/%n:INBOX=/var/spool/virtual/%d/%n } passdb passwd-file { args = username_format=%n /etc/virtual/%d/passwd } *** Everything works perfectly except for the fact that when virtual users authenticate, dovecot uses the configuration for real users first and then authenticate succesfully with the virtual configuration, generating those annoying log error messages: Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): check pass; user unknown Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=belforts(a)ragio.com.br rhost=201.6.150.188 Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): check pass; user unknown Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=belforts(a)telecomex.com.br rhost=201.6.150.188 Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): check pass; user unknown Oct 3 03:11:40 teleporto dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=info(a)mostrasocioambiental.com.br rhost=201.6.150.188 Oct 3 03:12:00 teleporto dovecot-auth: pam_unix(dovecot:auth): check pass; user unknown Oct 3 03:12:00 teleporto dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=comprovante(a)ragio.com.br rhost=200.204.124.212 This messages happen because dovecot is trying to check virtual users in the system password file (which just contains real users and not virtual users). So is there a way to force it to check virtual users just on the /etc/virtual/%d/passwd? I mean, if the domain is the real one, abusar.org, or it doesn't have a domain, it will check in the system passwords, but if it's some other domain except abusar.org, it should skip checking system passwords and check directly in the /etc/virtual/%d/passwd. I just don't know how to do that. Any hints? Thank you! -- Linux 2.6.27-rc8: Rotary Wombat http://u-br.net http://www.soninha23.can.br

[Dovecot] How to configure POP3 access in Dovecot?
by Andre Lopes 05 Oct '08

05 Oct '08

Hi, I'am new to Dovecot and Postfix... I have made a Postfix installation as "Internet with Smarthost". I'am using a domain in Godaddy, I have point "A (Host) Record" to my IP and the "MX Record" is also pointing to my IP. I have tested sending e-mail from my gmail.com account to my server, the server receive e-mails from gmail.comto my /home/andre/mbox successfully, the server is also sending mails by SMTP successfully. Now I need to configure POP3, I have been searching but I don't know what to do... I only need to receive e-mails in my windows machines in Outlook Express. I have test telnet in my localhost with "telnet mydomain.com 110" It appears: Trying 127.0.0.1 Connected to localhost +OK Dovecot ready Then I try to auth by telnet with: user andre(a)mydomain.com +OK pass mypass -ERR Authentication failed. I know that my password it's ok. When I try to "telnet mydomain.com 110" on other computer with another IP on Internet I get blank screen. My question: What can I do to, or what can I read to configure POP3 successfully? Best Regards, Andre.

[Dovecot] Quota exceeded message
by Timo Sirainen 05 Oct '08

05 Oct '08

I just realized that "quota" word probably doesn't mean much to many non-native english speakers. Do even non-technical native speakers understand what "Quota exceeded" really means? It's sent by quota plugin, currently in two different situations: 1) To the user doing the operation via IMAP COPY/APPEND. 2) More importantly: If deliver rejects the mail, it's sent to the sender. Here are some ideas for improvements: "Mail storage disk quota exceeded" "User's mail storage disk quota exceeded" "Quota exceeded - not enough disk storage capasity for the user" Any better ideas? I think it should mention "quota" word in any case so that people who understand it would know immediately what the error message is about. The current code doesn't allow cleanly using separate messages for 1) and 2), so I'd prefer to use the same one. But if you've a great suggestion for them separately I could do it.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 When I switch from one network to another, I sometimes get dovecot rejecting my connections.
