I had trouble with an instantssl cert, and found that what I needed to do was to also include all the certs up the chain, in a certain order, to keep the client from complaining about an invalid certificate. The first certificate in the pem file should be the the server certificate, followed by its chain starting from the root certificate down. Matt

[Dovecot] Copy from INBOX to INBOX corrupts file
by Andreas Jaekel 29 Oct '03

29 Oct '03

Aloha, again, Timo. Concerning the problem of copying within one folder... I'm still not sure it's not a problem I created myself, but I think it's caused by the use of the buffered IO routines in ostream-file.c ... you use io_add() to schedule write operations for later while simultanously reading new chunks from the very same file. This seems to confuse dovecot and make it write the copy to the strangest locations. I think when working within one folder I should use either blocking IO or a lot of calls to o_stream_flush()... what do you think? Greetings, Andy

Hi, Just a quicky, I can't see anything about how Dovecot handles certificate chains. 1, Does it handle them? 2, How, if if does? (Just got a cert from www.instantssl.com and I need there intermediate cert do validate it.., Works fine with Apache and Exim ) Cheers, Steve Gare - Xantara.Net -- 0845 123 5707

[Dovecot] Shared Folders
by D Canfield 21 Oct '03

21 Oct '03

I was just wondering if any thought has been given to shared folders and how they might be implemented yet? True shared folders are compelling enough to our organization that I've been looking into moving to Cyrus from Courier, but transparent folder migration looks to be nearly impossible for more than a handful of accounts... so that leaves me back at hoping courier or dovecot can eventually do what we want. We have a lot of organizations on campus that have a generic mail address such as "maintenance" of "physics." We don't like the idea of shared accounts (invariably either the mailbox gets forgotten about when a secretary changes, the password gets lost, or everyone on campus ends up with the password), so our policies require such generic accounts to be forwarded to a folder in a "real person's" account. This works well for us, but the users are clamoring for the ability to have more than one person access those folders. The problem with Courier's shared folders is that one person owns the folder and while others can see that mailbox, only the owner has write access. This kills most of the utility of shared folders, except for use as announcement areas. As I understand it, the reason Courier does it this way is that it uses the underlying unix permissions to control access to the mailbox. I'm thinking that even if dovecot uses the same concept for shared folders, it should be possible to allow multiple users to write to the folders if filesystem ACL support is used. At least ext3 and XFS both support ACL's, so there is a reasonable amount of support for them, and they would allow dovecot to give multiple users write access to the folders without having to manage it's own security system. The only issue would be that the delivery agent would have to make sure that that ACLs for a folder are kept consistent... I'm not even sure dovecot has to be ACL-aware. Anyway, if there is a completely different plan in the works, that's great too, but I wanted to at least voice an opinion and offer a suggestion of how to make it work. Thanks DC

[Dovecot] A view quirks
by Andreas Jaekel 21 Oct '03

21 Oct '03

Aloha Timo. I found a few odd things while playing with dovecot. At least one of them bugs me, but it might be a result of my own patches - I haven't testet it with mbox or maildir, yet. The details :) 1. * OK dovecot ready. A = (<return> Connection closed by foreign host. 2. * OK dovecot ready. A001 LOGIN xxxxxx xxxxxx A001 OK Logged in. A002 COPY 1 INBOX Connection closed by foreign host. (segfault) 3. [...] A003 SEARCH SUBJECT "test" * SEARCH 1 A003 OK Search completed. A004 SEARCH SUBJECT {6} + OK "test" * SEARCH A004 OK Search completed. I think these two searches should give identical results. 4. (my current nemesis) A002 CREATE bla A003 SELECT INBOX A004 COPY 1 bla A005 SELECT bla A006 COPY 1 bla * NO Internal error [2003-10-16 16:07:21] A006 OK Copy completed. If I copy from the current folder to the current folder I get a scrambled mailbox and an error. This might be selfmade, though. I'm currently trying to find this bug, but the various layers of [_oi]streams and callback and function pointer structs do not help :) I think the stream routines hide the mstream(istream(realstream(iostream))) and the ostream(_ostream(iostream)) behind the same file descriptor and the data gets written to the wrong position. BTW: what exactly is "max_pos"? Greetings and thanks! Andy

Hello! I've just subscribed and I'd like to ask. Is there any troubles if I change my imap-uw with davecot? Will davecot pick up imap-uw created folders (mboxes)? I use all protocols: imap, imaps, pop and pops. I've seen some problems with mbox was mention on this maillist. What kind of problem? -- Sem.

[Dovecot] problem getting mail from mbox
by Gavin Estey 16 Oct '03

16 Oct '03

I'm trying to set up dovecot and I'm running into a few problems. I just want to use IMAP for one user, everyone else gets POP3 from the existing (working server). $MAIL is set to /var/spool/mail/gavin_imap In my /var/spool/mail directory I now have a problem: -rw------- 1 gavin_im mail 1392 Oct 14 22:28 gavin_imap -rw------- 1 gavin_im popusers 0 Oct 14 21:54 gavin_imap When I try to get my mail, I guess it's checking the wrong file as I can't download anything. I also can't delete the file (which I find confusing as I am root): [root@chicken mail]# rm gavin_imap rm: cannot remove `gavin_imap': No such file or directory I actually have the same problem with the dovecot log file. I have this in my config: info_log_path = /tmp/dovecot -rw------- 1 root root 4436 Oct 14 22:40 dovecot [root@chicken tmp]# cat dovecot cat: dovecot: No such file or directory I don't get any obvious errors if I telnet in: [root@chicken tmp]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 LOGIN gavin_imap <pass> 1 OK Logged in. 1 SELECT Inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1066184985] UIDs valid * OK [UIDNEXT 1] Predicted next UID 1 OK [READ-WRITE] Select completed. 1 LOGOUT * BYE Logging out 1 OK Logout completed. Connection closed by foreign host. This is confusing the hell out of me. Is there anything obvious that I've screwed up? Thanks! Gavin.

[Dovecot] exchange, dovecot, mutt, evolution
by Krammer Clemens 16 Oct '03

16 Oct '03

Dear all, When I "migrate" my outlook folders to imapd (dovecot) it works well from a Windoze perspective, but if I open a migrated folder via imap (mutt, evolution) a cannot see the Senders. If i open the folder locally via mutt, the Senders are displayed correctly. By examining one folder with vi I recognised that there are no valid From headers but Return-Paths. Is there a common way to see the senders when connecting with imap? Best Regards, Clemens
