[Dovecot] RE: imap segv trying to list inbox
by Sam Powers 09 Mar '04

09 Mar '04

(This is releveant information to the one that Alex Moore just posted, but I'm not subscribed yet so I can't properly reply to that thread. Sorry for creating a new one.) I've got a crash in dovecot-imap when trying to list the inbox on a nonexistant directory. I'm not sure how it should be handled, but basically it's only happening when the directory in imap's MAIL environment doesn't exist. This is a problem for me because I'm trying to have dovecot create all the necessary directories in the specified environment, as I don't know if the user will pop/imap or recieve an email first, and the dir needs to either be already ready, or created upon reciept. I've already got postfix to create a ~/Maildir when a new mail comes in, but for my migration plan to work, I need dovecot to create this directory instead of segfaulting. ;) dante:/usr/lib/dovecot# MAIL=maildir:/tmp/nonexistant gdb ./imap (gdb) run Starting program: /usr/lib/dovecot/imap (no debugging symbols found)...(no debugging symbols found)... * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED] Logged in as root 1 list "" inbox (no debugging symbols found)...

Now, if I leave default_mail_env blank, and let dovecot's autodetection do the work, it seems to create a maildir in ~/mail. This works just fine, except it's the wrong directory. Otherwise, dovecot rocks, and in another, less automatic setup, I've been using it for the better part of a year with nothing but happy results, and appreciate your work. (Irssi too :) -Sam

[Dovecot] RE: imap process abends
by Alex S Moore 09 Mar '04

09 Mar '04

I am trying to setup dovecot imap on a test Solaris 8 box. I have dovecot POP3S running fine on another box, but I want to switch to IMAP. I see a successful login with a message like: Mar 8 13:22:47 sws601.mcsun.local imap-login: [ID 457029 mail.info] Login: sunuser1 [192.168.1.17] Then the Mozilla Mail client gets a message that the server disconnected. It appears to be from a segfault on the imap process. Here is the next message in syslog: Mar 8 13:22:47 sws601.mcsun.local dovecot: [ID 684838 mail.error] child 14108 (imap) killed with signal 11 On my ldap server, I see all of the appropriate entries for logging in getting the userdb info. So I think that I am past the login process, but I could be wrong. I setup a maildir environment on this server as follows: maildir:/export/home/imap/%u:INDEX=/var/indexes/%d/%n I have a test message to pickup and the maildir folders seem OK to me. Help, Alex

[Dovecot] Mails manipulation and indices
by Giacomo Cariello 06 Mar '04

06 Mar '04

I've recently manipulated the contents of my maildir, changing the content of some mail files (mime handling and such...). This broke dovecot since it expected different filesizes while reading contents of files that were previously indexed. Therefore dovecot returned some assert like this: imap(jwk(a)bug.it): file istream.c: line 163 (i_stream_seek): assertion failed: (v_offset <= stream->v_size) Obviously, the solution was to remove indices and have dovecot recreate them. I suppose it would be more "polite" to have this kind of routines (i_stream_seek etc) handle this case by requesting indices recreation for indices that are no longer "real", instead of just dropping connection with some "internal error" message.

[Dovecot] OS X 10.3, SSL, client connection hangs?
by Chad Bergeron 05 Mar '04

05 Mar '04

Ok, I've just installed Dovecot, and got it set up in xinetd for ssl and plain/pam. Everything looks good, I even got to the point where my client (mail.app) asked if I wanted to accept the new certificate I'd made. All good. But then the imap connection seems to hang right after negotiating. Nothing shows up in my logs except a disconnect, usually for inactivity. Has anyone else managed to set Dovecot up on 10.3, and has anyone seen this issue, or ones like it? Trying to figure out where to go from here... -Chad Bergeron

[Dovecot] imap MUA received
by Payton 05 Mar '04

05 Mar '04

Does anyone know where MUAs like Outlook, Entourage, and Mail.app get their 'Received' or 'Date Received' information from? It certainly doesn't appear to correspond with the mail headers, at least in my case, so I'm guessing it's possibly getting that data from the IMAP server? My mail clients (MUAs) show the 'Receieved' time as 5 hours off. I have qmail running as my MTA, and since it stamps emails' "Received" header with time in GMT (-0000) and I'm in EST (-0500) I thought that was the problem. However, I patched qmail to set the headers in -0500 instead, which worked as far as I can tell, but the MUAs *still* report the time incorrectly! (Time on both the client and the server are correct as well.) Here is my setup: dovecot running pop/imap mbox files (yes, i know this is bad) qmail as my MTA (used to list time as GMT in headers, but I patched it and now the headers list time in the local zone instead) -- ;; Payton Swick ;; ;; Repligen Corporation ;; ;; IT Systems Administrator ;; ;; payton(a)repligen.com ;;

[Dovecot] RFE: more graceful handling of startup errors
by Matthias Andree 04 Mar '04

04 Mar '04

Hi, I've just had a funny (but not amusing) incident after boot-up on a Dovecot server. rpc.mountd (NFS server) grabbed port 995 (POP3-SSL), and the whole Dovecot lot (POP3-SSL, IMAP-SSL, IMAP) refused to start up, rather than just letting POP3-SSL fail with "address in use". May I request to kindly consider letting Dovecot services fail individually rather than all of them, at least optionally? TIA, -- Matthias Andree Encrypt your mail: my GnuPG key ID is 0x052E7D95

Might have been some problem related > to their specific environment. I have also had a similar problem where there was partial curroption of an mbox folder. After that point in time, I could not properly read some messags using Openwebmail. I did not have time to fully investigate the exact cause and the exact form of the curroption, but I did want to let you know that it is an issue. Thanks, Joe

[Dovecot] debian unstable : mutt polling imap mailboxes
by Kai Hendry 02 Mar '04

02 Mar '04

Package: dovecot Version: 0.99.10.4-2 I am accessing my IMAP folder on my ~/Maildir using mutt via Dovecot and I have this problem whereby mutt incorrectly reports I have new mail in a "mailboxes" polled mailbox. This happens all the time when I press the key bound to change mailbox. I use courier IMAP at school, and I have not experienced this problem. A bug with dovecot or mutt?
