[Dovecot] syslog() logging problems
by James Moser 26 Apr '04

26 Apr '04

was wondering if anyone else has had problems with dovecot logging to syslog? When I start the server it works fine, then after an hour or so it stops.. restarting the server always makes it work again. -- James L Moser james(a)powweb.com PowWeb Hosting http://www.powweb.com /(bb|[^b]{2})/, that is the Question. mysql>SELECT * FROM user WHERE clue > 0; Empty set (0.03 sec) Health is merely the slowest possible rate at which one can die...

26 Apr '04

Greetings, I saw mention in results from a google search that there was some support in dovecot CVS for shared folders, is there some docs on how to use them? Provided there is in fact support for them in CVS. Thanks. -- Gareth J. Greenaway | gareth(a)wiked.org SCLUG - Simi Conejo Linux Users Group http://www.sclug.org

How about just running fetchmail in daemon mode, so it's polling for messages instead of running on demand? Then you don't need to worry about any special integration issues. Julian.

[Dovecot] RE: Missed config option
by Alex S Moore 26 Apr '04

26 Apr '04

I am trying to sync a set of maildir folders from a dovecot server and a different imap server on a different host. Using a perl tool called imapsync. The tool says the following about the two servers capabilities: >From capability : IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED To capability : IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION No NAMESPACE capability in imap server sws601.mcsun.local Give the separator character with the --sep1 option The From server sws601.mcsun.local is dovecot. What did I miss that causes the NAMESPACE capability to not be seen from dovecot? What is the separator character? Thanks, Alex --

[Dovecot] imap errors filtering folders with evolution
by Brent Hills 26 Apr '04

26 Apr '04

Hello, I posted earlier to the Ximian Evolution Users list. It was suggested I follow up in relation to dovecot. They also indicated the timestamp in the error message was coming from dovecot. When filtering a folder on a dovecot (0.99.10) imap server with Evolution version 1.46 I receive: Error while 'Filtering Folder' Imap command failed internal error [YYYY-MM-DD HH:MM:SS] The timestamp seems to be the current time. The filters used are primarily move to folder where the destination folder is another imap folder on the same server. The error can be reproduced reliably if I select a large number of email to filter. There are about 10 filters all moving to different folders based on criteria. If I select smaller number of email the error occurs but less predictably. Eventually, it will filter all the email so its not a particular one that it hangs up on. Is anyone familiar with this issue? Brent Hills.

[Dovecot] dovecot dies - mabye a clue?
by Steven Stern 26 Apr '04

26 Apr '04

Dovecot died twice today. This was in the maillog: Apr 9 17:50:27 ciscy pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded Apr 9 17:50:27 ciscy dovecot: Login process died too early - shutting down I think I can cause it to happen reliably and I'm asking for other to test this scenario: Open several terminal windows. In each, type "telnet 127.0.0.1 110". Wait for the dovecot POP prompt and do nothing. After each times out, up-arrow and try again. Sometime in the next hour, dovecot will die. -- Steve

[Dovecot] file permissions help!
by smk 26 Apr '04

26 Apr '04

Hi all! Ran into a problem and hopefully i can get some help. OK here is my set up: - dovecot-0.99.10.4 + MySQL patch. - Redhat 9 The authentication part works just fine. It gives me the following entry in the log file: imap-login: "Apr 12 22:15:10 "Info: Login: USER(a)DOMAIN.com [127.0.0.1] But there is a problem with dovecot reading the mbox file (I think). In the error file I get this entry: imap(USER(a)DOMAIN.com): "Apr 12 22:15:10 "Fatal: Failed to create storage with data: /export/htdocs/DOMAIN.com/mail/USER dovecot: "Apr 12 22:15:11 "Error: child 18613 (imap) returned error 89 Of course the user and domain info was changed. I am out of ideas but thats not to say its something easy or something I completely looked over. This is how I compiled dovecot: CPPFLAGS="-I/usr/local/mysql/include/mysql -DPASSDB_MYSQL -DUSERDB_MYSQL" \ LDFLAGS="-L/usr/local/mysql/lib/mysql/ -lmysqlclient" \ \ ./configure \ --prefix=/usr/local/imapd \ --disable-ipv6 \ --without-pop3d \ --without-ssl \ --with-storages=mbox \ --enable-debug thanks in advance.

[Dovecot] Problem with flags
by Jeff Hoskinson 26 Apr '04

26 Apr '04

Greetings! I'm having a problem with flags not working correctly. I'm using Mozilla Thunderbird as my mail client, and Dovecot 0.99.10.4 as part of Debian on a Sparc box. The thing that doesn't seem to be working right is Thunderbird's Label feature, which uses custom IMAP flags. I noticed that once I labeled a message, I couldn't un-label it. I recorded this exchange between Thunderbird and Dovecot while using the Label/None command on a message: 5235 uid store 35 -Flags ($Label1 $Label2 $Label3 $Label4 $Label5) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label5) UID 35) 5235 OK Store completed. Even though Thunderbird is sending the -Flags command for all its custom flags, the message is still retaining two of those flags. Just out of curiousity, I tried changing the flag of that same message to something different, and recorded this exchange: 5259 uid store 35 +Flags ($Label2) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label2 $Label5) UID 35) 5259 OK Store completed. 5260 uid store 35 -Flags ($Label1 $Label3 $Label4 $Label5) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label2 $Label5) UID 35) 5260 OK Store completed. So it seems the +Flags command works, but not the -Flags? Or does it have something to do with sending more than one flag at a time? Any help would be appreciated. Thanks, -- Jeff

[Dovecot] [OT] Is there a secure reverse IMAP proxy
by Sven Kirmess 26 Apr '04

26 Apr '04

This question is off topic. I ask this list because the question is related to security and IMAP and I guess the people in this list know a lot about both of that. Is there a secure reverse proxy for the IMAP protocol? Something you can install on a bastion host which checks the IMAP traffic before forwarding it to the internal IMAP server? There are these proxies for WebMail to IMAP connections but as far as I can tell they were not created for security reasons and not with security as primary goal. Sven

[Dovecot] SSL Ciphers
by John Wentworth 26 Apr '04

26 Apr '04

I have dovecot running as a pop3s server on port 995 it works great with sendmail and I run nessus to check security issues nessus reports this The SSLv2 server offers 3 strong ciphers, but also 0 medium strength and 2 weak "export class" ciphers. The weak/medium ciphers may be chosen by an export-grade or badly configured client software. They only offer a limited protection against a brute force attack Solution: disable those ciphers and upgrade your client software if necessary I have previously disabled weak ciphers in apache but cannot figure out how to disable the weak ciphers in dovecot Any help would be appreciated john
