[Dovecot] Re: corrupt attachments
by Brian Thompson 08 Dec '05

08 Dec '05

Hello all, any suggestions on this? It seems like a pretty serious issue and it hasn't reoccurred since we switched back to UW imapd. As I mentioned, it seems to be related to dovecot compiled on Solaris 10/x86... The same code compiled on Solaris 8/sparc seemed to work well. -Brian Brian Thompson wrote: > > Not sure if this has already been covered, but any pointers > or suggestions would be greatly appreciated. > > We just realized last night that dovecot-stable seems to be > corrupting the attachments within users' inboxes. > > In an attempt to resolve the problem, we upgraded the > mail server here to Dovecot 1.0alpha4 but it didn't help. > > To the best of our knowledge we didn't start experiencing > this phenomena until we migrated from Solaris 8/Sparc > to Solaris 10/x86 about 3 weeks ago. > > To be more specific: > A non-corrupt attachment can be sitting within a user's > mail spool (mbox format) and live there without a problem > until an imap client goes to download the attachment via > dovecot. > > At that time, dovecot seems to be stripping the last four > characters from each base64 encoded ascii line within the > attachment and rewriting the message within the mail spool > without those characters.

[Dovecot] "pop before smtp" dovecot.conf
by Jean-Marc Pigeon 07 Dec '05

07 Dec '05

Bonjour a Tous, I would like to generate (on the fly) a list "popbeforesmtp" when dovecot POP/IMAP authentication succeed. Intended Format will/should be such as: 'timestamp_in_second' user_id remote_ip one user per line. My guess we have all the needed information within dovecot to make such list. But I have seen no way to 'trick' dovecot (dovecot-1.0.alpha3) to do it... Could someone on the list able to give me some advices? I know there is Perl script to scan maillog file and extract information from collected data, but this seem to me 'a kind of the very last option'.... May be the trick can be achieved using 'executable' function? Ideally I'll like to have an entry in dovecot.conf, like... popbeforesmtp=/somewhere/in/the/tree A bientot -- ========================================================================== Jean-Marc Pigeon Internet: Jean-Marc.Pigeon(a)safe.ca SAFE Inc.

[Dovecot] Pop-before-smtp and MySQL?
by Matteo Garofano 07 Dec '05

07 Dec '05

Hi, I found that dovecot have many nice features. Now I write because I'm tring to setup the dovecot server, I would substitute a qpopper daemon (patched for mysql authentication) The problem I find is to set up the pop-before-smtp using sql (mysq) as written in http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot (Waiting for post_login ;-) I would use the script popbsmtp.sh and not a perl pig. (I'm using qpopper patched to store the relay IP in mysql and it works) I set .my.cnf in /root What happen is that the $3 don't contain the IP that should be written to the DB. Is there something I miss ? I tried to modify the dovecot.conf file like this mail_executable = /usr/local/libexec/dovecot/popbsmtp.sh /usr/local/libexec/dovecot/pop3 %r "%r" and it write to the db the litteral value %r and not the ip, otherwise it write nothing. the connection with mysql works and any other operation on it works. this should be the last step for my setting. Have you any hint? Thanks in advance and best regards Matteo Garofano

[Dovecot] Tools to analyze status/stats?
by wolff 07 Dec '05

07 Dec '05

Hello, I recently installed dovecot on a server running Debian. I only have 10 users, but we probably have 6Gig of email between us. Things were working flawlessly for a couple of weeks, and I'm still getting email, but the last few days we are getting fewer emails that we typically do. So although things seem to be working well, everyone is suspicious something is wrong due to the lack of email volume. Is there a size limit that dovecot can manage? Are there any admin tools to get status messages for dovecot? Are there any reporting tools to show how many messages are processed/managed by dovecot? Thanks!!

[Dovecot] 1.0alpha4: pop3_reuse_xuidl patch
by grant beattie 06 Dec '05

06 Dec '05

hi all, this is needed to make the pop3_reuse_xuidl option work in 1.0alpha4. I am using maildir and I noticed that for each message which doesn't have an indexed X-UIDL header, the entire message is read from disk. as this is reading only headers, it is probably reasonable to stop reading at the end of the headers. it would also be neat if dovecot could be configured to only try reading X-UIDL headers from messages if the mailbox indexes don't exist, since I guess it would be common to want to preserve existing X-UIDLs but not bother for new messages (perhaps some mtime comparison, or something). opinions? I haven't looked at the source enough yet to be able to do this, but these two optimizations would vastly reduce the amount of disk IO as a result of using this option. grant.

[Dovecot] Unknown message data

Running 1.0-alpha4 on Sarge, when I move a message with a blank subject from one mailbox into another, and then open that destination mailbox in Pine, Pine gives me the error "Unknown message data: 1001 FETCH", where 1001 is the UID of the message. Paul

[Dovecot] Struggling with namespaces...
by Kev Latimer 06 Dec '05

06 Dec '05

Hi all, I've been using dovecot 0.99x as a basic POP3/IMAP server at a couple of sites for a few months now and am very happy with it's simplicity, stability and performance, especially over the rather 'clunky' courier and the mammoth cyrus. I'm building up a top level mail server for our organisation and am desperate to use dovecot in there but I'm really struggling with using namespaces to create some shared maildirs - note that in this case I'm using the 1.0alpha4 debian packages that recently made it into 'etch'. I have very simple requirements here - I just want to be able to have some common folders subscribable by certain users, for my testing an announcements folder accessible by all and an archive folder I want to place some restrictions on. Whenever someone needs access to someone elses folder (ie. holiday watch), symlinking should be sufficient. I can start up dovecot, log in as a user (I authenticate against LDAP btw), see the directories specified in my namespace directives be created but I can't subscribe to anything. Squirrelmail gives an error stating "[TRYCREATE] Mailbox doesn't exist: archives" while Thunderbird shows the folder names in grey and refuses to subscribe. Am I missing the point of namespaces or have I failed to create something in the folders to get them to play? I read something about a dovecot-shared file but I think this is a 0.99 thing, although I tried creating the file with the permissions I wanted applied to the folder and it didn't do anything... I did notice that when the folders are created, they are created owned by the first user logged in. I have tried chmod'ing them to 777 to see if it makes a difference, but alas, no. The relevant bit of dovecot.conf is: namespace private { separator = / #prefix = #location = inbox = yes #hidden = yes } namespace public { separator = / prefix = announcements/ location = maildir:/var/mail/announcements/Maildir } namespace shared { separator = / prefix = archives/ location = maildir:/var/mail/archives/Maildir } I'm sure I'm just being picky, but a better explanation of namespaces in the docs might be in order, maybe with some examples. If I get this sussed out, I'll put one in the wiki ;) Any help much appreciated! Kev

[Dovecot] 1.0.alpha4 process creation wierdness
by Mark Rosenstand 06 Dec '05

06 Dec '05

Hi list! I'm a little confused. I have set "login_process_per_connection = yes" and "login_processes_count = 1", and this is how my pstree looks when nobody is connected: dovecot -,- dovecot-auth `- imap-login However, when I connect with a client it looks like this: dovecot -,- dovecot-auth |- imap `- 2*[imap-login] I would expect it to only have one imap-login running. Anyway, when I disconnect the client, the imap process exits but imap-login keeps running: dovecot -,- dovecot-auth `- 2*[imap-login] This is when it gets really wierd. When I connect a client again, my pstree looks like I would have expected it to on my first connect: dovecot -,- dovecot-auth |- imap `- imap-login If I re-connect, we start over again (i.e. dovecot-auth, imap, 2 * imap-login). Anybody got a clue what's going on? :-) -- .-. Mark Rosenstand (-.) oo| cc ) /`'\ (+45) 255 31337 3-n-( (\_;/) mark(a)borkware.net _(|/`->
