[Dovecot] CentOS yum update causing died unexpectedly
by dovecot＠corwyn.net 26 Mar '10

26 Mar '10

Running CentOS 5.x running a postfix/dovecot implementation. Dovecot 1.1.8. I just ran a full system update in my dev environment, and now I'm occasionally getting: Mar 26 07:15:43 example dovecot: auth(default): worker-server(test222(a)int.example.com,127.0.0.1): Aborted: Worker process died unexpectedly in /var/log/maillog. Any suggestions on where to look to figure out what's causing this? I don't see that error at all in the past 4 weeks of logs in production.

Hello, i use successfully mysql-quotasystem with dovecot 1.2.11 on different servers except for mysql 4.0 servers dovecot internally uses sql: "ON DUPLICATE KEY UPDATE" which was introduced in mysql 4.1 Is there a chance to make this statement mysql 4.0 compatible or should i update mysql? i want to avoid updating mysql because some old software is running which is not compatible to higher mysql versions. Thanks, Andre

[Dovecot] Dovecot 2.0beta4
by Renaud Allard 25 Mar '10

25 Mar '10

Hello, It seems dovecot 2.0 beta4 still behave strangely without tcpwrap. I still get the errors: 2010-03-25_17:26:59.33848 Fatal: service(tcpwrap) access(/opt/dovecot/libexec/dovecot/tcpwrap) failed: No such file or directory 2010-03-25_17:27:00.36108 Fatal: service(tcpwrap) access(/opt/dovecot/libexec/dovecot/tcpwrap) failed: Permission denied It's easy to solve by touching and chmodding 0755 that file, but prod version shouldn't exhibit that behavior. Best Regards

[Dovecot] 1.2.11 nfs_flush_file_handle_cache_dir problems
by Ade Fewings 25 Mar '10

Hi chaps We're using the mbox_snarf plugin to snarf mail from /var/mail/%U to ~%U/Mail/inbox and using dotlocking on all accesses. This is on Solaris with NFS mounted home directories. We're getting a few (very few) of these for just a couple of users: Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy Which, having searched, I see some discussion of in the past, but not with 1.2. We're using: mail_privileged_group = mail For the /var/mail 'inboxes', which I thought would tackle this problem. Couple of questions, if you don't mind: 1. Does dovecot user need to be a member of the mail group? 2. Does this error message represent a real problem that needs solving? It's very strange how rare it is and that only a few select users have encountered.

[Dovecot] Dovecot-1.2 + Sieve + Managesieve on Debian
by Proskurin Kirill 25 Mar '10

25 Mar '10

Hello! I think about migrate from FreeBSD to Linux because I need DRBD for clustering. I want to use Debian Lenny but run on some problems. I want near latest Dovecot packages. Native repos are too old. Backports seems to don`t have a Sieve&Managesieve support and we need it(am I wrong?). Stephan Bosch auto packeges is not for production. How could I solve this without make own packages? What Debian folk`s do in this situation? P.S. I don`t want to use RedHat like OS because I not familiar with it. -- Best regards, Proskurin Kirill

[Dovecot] can Dovecot do VERP?
by Rick Graves 25 Mar '10

25 Mar '10

Hey, I have several thousand email addresses, the vast majority of which are definitely no good, and I want to figure out which are good. So I will send out an email to all the email addresses. By making a list of the ones that bounced, and comparing that list with the full list, I can determine which are still good. This is for a non-profit association -- I am not in the spam business. Knowing exactly which emails bounced would be much easier if I could set up an in box implementing VERP. http://en.wikipedia.org/wiki/Variable_envelope_return_path In other words, I want an in box accepting all mail where the email addresses match a wildcard pattern like this: mail_admin_??????(a)domain.org, where ?????? are 6 digits. The digits would be a scrambled contact ID. Since they will be digits only, here is the regular expression: mail_admin_\d{6}. (We will pick a wildcard pattern that does not conflict with any existing address on the server.) Sending the outgoing emails, each with a different "From" address matching the wildcard pattern, is not a problem -- I have a working python script for this. The challenge is getting one in box to accept emails with different "From" addresses (matching the wildcard pattern). We are running IMAP server Dovecot 1.0.7. How do I set this up in the IMAP server to accept emails to addresses matching the wildcard pattern? Thanks, Rick Graves

Re: [Dovecot] quota dict with mysql 4.0

(sorry, i only read the digest version of list and always create i new thread by "fake-Re") Hello, >> Perhaps you can implement some updating procedure that >> would only involve a percentage of your users at one time. no way, i want to fix this! but i need help because i have no idea of c-programming. i can read the code a little bit, but never lerned it. solution is to edit dovecot-1.2.11/src/lib-dict/dict-sql.c i can avoid using ON DUPLICATE KEY UPDATE by changing line 91 to: orig: dict->has_on_duplicate_key = strcmp(driver->name, "mysql") == 0; changed: dict->has_on_duplicate_key = strcmp(driver->name, "mysqlXXX") == 0; this works only 50%. if a user has no entry in quotatable, dovecot is updating his quota with 2 queries: INSERT INTO quota (bytes,username) VALUES ('2456','myuser') INSERT INTO quota (messages,username) VALUES ('2','myuser') The first query works, the second throws an error because username-field is uniqe. Duplicate entry 'myuser' for key 1 So i have to find a way to make this query in one step: INSERT INTO quota (bytes,messages, username) VALUES ('2456','2','myuser') or turn the second insert into an update update quota SET messages='2' where username='myuser' But iam afraid this is too much for my c-skills. I need help of an C-Crack or timo as developer. if timo could create a switch for mysql 4.0 would surely be the best. Thanks, Andre
