[Dovecot] messages_count too large (1121 > 1115)
by Moritz Willers 15 Dec '05

15 Dec '05

I've seen this was mentioned before but remains unsolved. I upgraded Dovecot from 0.99 to v1.0.alpha4 yesterday and it rendered my inbox inaccessible: Dec 15 00:09:07 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/.imap/INBOX/dovecot.index: messages_count too large (1121 > 1115) I've since moved that inbox away so I can view my new mail again. The error has moved with the mbox file: Dec 15 00:27:41 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/old-inbox/.imap/200407-200512/dovecot.index: messages_count too large (1121 > 1115) Dec 15 00:27:41 sand dovecot: child 83886 (imap) killed with signal 11 This is on FreeBSD 4.8 (yes, yes ... but: "up 687 days" which is quite nice) all running on local disk. So earlier suspicions about NFS or MacOS X are out of the window. One day I'll move move from mbox to dir format and the problem will go away, in the meanwhile, I thought it would be good to resolve this issue. Let me know how I can help to get to the bottom of this. - mo

[Dovecot] Best way to upgrade from 1.0a4 to 1.0a5
by Cliff Hayes 15 Dec '05

15 Dec '05

Hello all, I have 1.0 Alpha 4. Is it better to shut down sendmail, uninstall dovecot 1.0a4 then install 1.0a5, or just install 1.0a5 over the top of 1.0a4? Thanks, Cliff

[Dovecot] Variable '%r' doesn't transfomr in Postgres query
by Sebastjan Trepca 15 Dec '05

15 Dec '05

Hi, i'm using postgres for authorization. When I switched from a4 to a5 authorization stoped working. Query in conf file for postgres looks like this: password_query = select password from auth('%u','%r'); But in logs, the transformed query looks like this: Performing query: select password from auth('test','%r'); Looks like you don't transform that remote IP parameter?

[Dovecot] writing an MDA, help me avoid corrupted indexes
by Lee Howard 15 Dec '05

15 Dec '05

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes the mail off to SpamAssassin. From there I need an MDA to dump any mails detected as spam into a common spam folder, discard any mails with viruses (antivir) and send a notification to me, and then drop good mail into the appropriate maildir directory for the virtual users to get via both POP3 and IMAP. I could conceivably use procmail to do that MDA, and I've done similar things with procmail in the past, but my growing experience with procmail indicates that procmail is too ferocious for what simple work I need done, and too difficult to make work right in a virtual-user environment. So I've written my own little MDA with a few lines of shell that will take the mail from Postfix+SpamAssassin and ultimately deposit mails in the maildirs. So far so good, except that I keep seeing corrupt indexes... probably because I'm not touching the indexes at all with the MDA. My guess is that in order for the MDA to properly deal with maildir it needs to adjust the indexes after depositing new mail. Okay. So can someone either give me a pointer to the proper documentation on this, including the index file formats, or perhaps just explain it to me? Maybe I'm missing a larger picture of maildir handling? I've glanced through http://www.dovecot.org/doc/index.txt but I notice that the index files are not ASCII, so I'm not sure where to start at understanding that documentation. Any and all help would be appreciated. Thanks, Lee.

[Dovecot] assertion failed: (conn->refcount > 1)
by David Schweikert 15 Dec '05

Hi, Sometimes (happens maybe twice in a day), I have the following errors: Dec 15 16:10:17 dovecot: auth(default): file auth-client-connection.c: line 33 (auth_client_send): assertion failed: (conn->refcount > 1) Dec 15 16:10:17 dovecot: child 17152 (auth) killed with signal 6 Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dovecot seems to recover though, because afterwards it still works. I did however notice that the logging-in seemed to hang for a while (some seconds).

[Dovecot] How to serve two "inboxes" via imap
by Roderick Johnstone 15 Dec '05

15 Dec '05

Hi In our setup we have mail delivered to /var/spool/mail/<username>. Many users like thunderbird as their MUA and we typically have thunderbird set up to read mail using a movemail account with the local mail directory set to ~/mail so that the mail can be read easily by pine as well. So, when a user clicks the "Get Mail" button in Thunderbird, mail is moved from /var/spool/mail/<username> to ~/mail/Inbox. Although I can serve other folders from ~/mail my imap clients don't see ~/mail/Inbox, they see just /var/spool/mail/<username> as INBOX. Can anyone advise please how to make the ~/mail/Inbox available as well via imap using dovecot (currently using 1.0-alpha5). We currently use default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u Many thanks Roderick Johnstone

[Dovecot] checkpassword authentication
by Florian Füessl 14 Dec '05

14 Dec '05

Hi, does anyone already use the checkpassword authentication scheme? I have not found any description how I have to configure dovecot in order to work together with qmails checkpassword. Enabling passdb = checkpassword /bin/checkpassword in dovecot.conf starts /bin/checkpassword for every authentication request, but the result does not seem to matter for the authentication. Without enabling a userdb entry, dovecot claims not to be able to find out the uid, gid and home of the user, although checkpassword replies these values. Setting static values with "userdb = static uid=$fixed_mail_uid gid=$fixed_mail_gid home=/maildata/%d/%n" results in being every login successful, no matter if the checkpassword authentication is ok, or not. I'm using the latest dovecot nightly build from 22. Nov. 2005. - Florian
