[Dovecot] Cyrus migration - Header version 6 not supported
by Arnaud Limbourg 16 Oct '05

16 Oct '05

Hello, I was previously running a cyrus server which I realized later on is overkill for what my needs so I would like to switch to dovecot. Unfortunately the cyrus2courier utility to migrate the mails gives me the error Header version 6 not supported I was using cyrus 2.2.3. Does anybody have any advice on how I could migrate all the mails ? Thank you. Arnaud.

[Dovecot] Need help with SQL queries after updating to 1.0a3
by Jonathan Vanasco 16 Oct '05

16 Oct '05

I upgraded to 1.0a3 - i have everything in the config migrated over, but I'm unsure about the way i should be querying postgres my db handles virtual accounts only, and is set as such: CREATE TABLE accounts ( local_part VARCHAR(64) NOT NULL, domain VARCHAR(64) NOT NULL, password VARCHAR(64) NULL, home_dir VARCHAR(256) NOT NULL, uid INTEGER DEFAULT '1003', gid INTEGER DEFAULT '1003', active CHAR(1) DEFAULT 'Y' ); so an entry would be something like: user | domain.com | md5('passwprd') | /path/to/maildir/ | 1003 | 1003 | Y I've rewritten the password query as such: password_query = SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = '%n' AND domain = '%d' AND active = 'Y' ; but i can't get things to work with the user query user_query = SELECT home_dir AS home, uid, gid FROM accounts WHERE local_part = '%n' AND domain = '%d' ; can anyone point me in the right direction? the docs in the distribution aren't very clear, and the wiki seems to have more .9 info than 1.0 info this is what i've gotten of of auth_debug: Oct 11 11:53:37 rsrr1 dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=66.250.131.114 rip=209.73.1.130 resp=xxxxxxxxxxxxxx Oct 11 11:53:37 rsrr1 dovecot: auth(default): sql(test(a)mydomain.com, 209.73.1.130): query: SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = 'test' AND domain = 'mydomain.com' AND active = 'Y' ; Oct 11 11:53:37 rsrr1 dovecot: auth(default): client out: OK 1 user=test@ mydomain.com Oct 11 11:53:37 rsrr1 dovecot: auth(default): master in: REQUEST 26 93326 1 Oct 11 11:53:37 rsrr1 dovecot: auth(default): passdb(test@ mydomain.com,209.73.1.130): passdb didn't return userdb entries Oct 11 11:53:37 rsrr1 dovecot: auth(default): userdb(test@ mydomain.com,209.73.1.130): user not found from userdb Oct 11 11:53:37 rsrr1 dovecot: auth(default): master out: NOTFOUND 26 Oct 11 11:53:37 rsrr1 dovecot: imap-login: Internal login failure: user=<test@ mydomain.com>, method=PLAIN, rip=209.73.1.130, lip=66.250.131.114, TLS

[Dovecot] Dovecot versus libsafe 2.0.15
by _ 16 Oct '05

16 Oct '05

Hi, I encountered a problem using Dovecot (todays CVS, 11/10/2005) with libsafe, systemwide install. Dovecot silently dies. Here is the end of the systrace output I got: bind(6, {sin_family=AF_INET, sin_port=htons(143), sin_addr=inet_addr("0.0.0.0")}}, 16) = 0 getsockname(6, {sin_family=AF_INET, sin_port=htons(143), sin_addr=inet_addr("0.0.0.0")}}, [16]) = 0 listen(6, 8) = 0 fcntl64(0x6, 0x3, 0, 0x8072ed8) = 2 fcntl64(0x6, 0x4, 0x802, 0x8072ed8) = 0 fcntl64(0x6, 0x1, 0, 0x8072ed8) = 0 fcntl64(0x6, 0x2, 0x1, 0x8072ed8) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 8 setsockopt(8, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 setsockopt(8, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0 bind(8, {sin_family=AF_INET, sin_port=htons(993), sin_addr=inet_addr("0.0.0.0")}}, 16) = 0 getsockname(8, {sin_family=AF_INET, sin_port=htons(993), sin_addr=inet_addr("0.0.0.0")}}, [16]) = 0 listen(8, 8) = 0 fcntl64(0x8, 0x3, 0, 0x8072ed8) = 2 fcntl64(0x8, 0x4, 0x802, 0x8072ed8) = 0 fcntl64(0x8, 0x1, 0, 0x8072ed8) = 0 fcntl64(0x8, 0x2, 0x1, 0x8072ed8) = 0 dup2(4, 0) = 0 dup2(4, 1) = 1 dup2(4, 2) = 2 fork() = 8739 --- SIGCHLD (Child exited) --- _exit(0) = ? kind regards Sascha Warner

[Dovecot] Cannot see new messages in Inbox
by Mark Farmer 16 Oct '05

16 Oct '05

Hi, just wondering if anyone has any suggestions on this. I'm having a rather odd problem in that I cannot see new emails in my IMAP inbox, this is true for both Thunderbird & Squirrelmail. I know the mails are arriving & being delivered correctly as I see the logs for postfix & procmail, and I can also list them from a command prompt on the Linux mail server. The really odd thing is that I can see new mail in other folders within the same mailbox (maildir) without issue, it's only the inbox that seems to be exhibiting the problem. Nothing has changed on the server and all permissions look fine. The only thing I can think of is that I reinstalled my other machine with Linux the other day & setup Thunderbird as normal - I didn't have any problem at the time but yesterday I noticed the problem. I have tried stopping & restarting the dovecot service a few times but this hasn't helped. I've had this running for months now & this just seems to have cropped up, very strange. Any thoughts anyone? farmorg

[Dovecot] How to set up a passwd file for virtual hosting
by Richard Freeman 16 Oct '05

16 Oct '05

Hi, Exim4 is running fine and I am trying to set up Dovecot 0.99 to handle virtual users (http://wiki.dovecot.org/moin.cgi/VirtualhostingWithExim) so I don't have to set up user accounts for each e-mail address I want to server out via pop3. I need to create a user and passd file, a bit like /etc/passwd, but in a different location for my dovecot virtual users. I can create a blank file such as /etc/dovecot/users (beware my increasing vi skills...) but how do I add users and passwords to this? Can I just type them in and separate them with colons? If so, how would I add a password to the file? I am happy using the passwd command which alters my user passwords in /etc/passwd. Can I use it or something similar to create the passwords for the users in my new file /etc/dovecot/users ? Is there any way I can use an MD5 hash or CRYPT format for the passwords? Yours, Richard

[Dovecot] FreeBSD Ports Issues
by Barry Jeung 16 Oct '05

16 Oct '05

Installed dovecot for the first time, using the FreeBSD port. Found 2 issues with the port, and I've only been able to resolve one of them. First of all, the port, (or perhaps dovecot) does work with mysql 4.1 encryption. I had to create a user with access to the mysql table, then do 'set password = old_password('password');' in order to get dovecot to talk to the server. The second issue, is that dovecot seems to be ignoring my user_query settings. I have the following in dovecot-sql.conf: password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 125 as uid, 125 as gid FROM mailbox WHERE username = '%u' The password query works, however the user query seems to default to something else, and no matter how I change the user_query line in dovecot-sql.conf, it uses the same query. Here's an excerpt from my logs: dovecot: Oct 11 03:19:30 Info: Dovecot v1.0.alpha3 starting up dovecot: Oct 11 03:19:31 Info: auth-worker(default): mysql: Connected to (null) (postfix) dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): query: SELECT password FROM mailbox WHERE username = 'user(a)example.com' dovecot: Oct 11 03:19:35 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=5.6.7.8 rip=1.2.3.4 resp=AGJqZXVuZ0Bjb2JhbHQtaXQuY29tAHRlc3Q= dovecot: Oct 11 03:19:35 Info: auth(default): client out: OK 1 user=user(a)example.com dovecot: Oct 11 03:19:35 Info: auth(default): master in: REQUEST 1 13590 1 dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): SELECT home, uid, gid FROM users WHERE userid = 'user(a)example.com' dovecot: Oct 11 03:19:35 Error: auth-worker(default): sql(user(a)example.com,1.2.3.4): User query failed: Table 'postfix.users' doesn't exist dovecot: Oct 11 03:19:35 Info: imap-login: Internal login failure: user=<user(a)example.com>, method=PLAIN, rip=67.188.145.230, lip=209.25.157.150, TLS So obviously the query fails because that table doesn't exist. However that's not the query that I have in the configuration file. As a matter of fact, I have no idea where it's pulling that query from. Any pointers would be greatly appreciated.

[Dovecot] Dovecot on FC3 with Active Directory authentication
by Jeff Ramsey 16 Oct '05

16 Oct '05

I am building an IMAP server that uses Dovecot/Sendmail on FC3 to replace our POP server that uses Dovecot (via POP)/Sendmail on FC2. My new server is authenticating users via winbind/smb against my WIndows 2003 Active Directory. The authentication is working great. The problem come up when a user gets an email and has not ever logged into the IMAP server via SSH, local, or GDM, therefore that user has no home directory. /etc/pam.d/ssh, /etc/pam.d/login, and /etc/pam.d/gdm all have a line calling mkhomedir.so, which is using the /etc/skel home directory skeleton to create the user's home dir upon successful login, however, when I add that line to /etc/pam.d/dovecot, I get a permission denied error in /var/log/maillog. I'm assuming this is because dovecot is running as the user at this point, and therefore does not have the necessary permissions to create a folder under / home/DOMAIN/, which is where the home dir is supposed to be. If I manually create the folder, and set it's permissions, or if the user logs in via any of the before-mentioned methods, dovecot and sendmail work great. Does anyone else run a similar setup? If so, how did you overcome this problem? If not, can some Linux gurus recommend either altering the write permissions on the /home/DOMAIN directory, or should I try to call the mkhomdir app earlier in the process somehow? Any help would be appreciated. I'm trying to make this as seamless as possible. Basically, I can manually create all the home dirs well enough, but when I add a new user to the Active Directory, it would be nice if this part was automated as much as possible. Thanks, Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Mapping username only for auth
by Andy Cravens 16 Oct '05

16 Oct '05

I am running Dovecot alpha 3 with authentication from the local shadow file. I'd like to change the authentication to use our radius server. I can probably do this through pam. The usernames on the mail server are set up as first initial + last name ( jdoe for John Doe ). The usernames on the radius server are the employee number. Is there a way to map the username to the employee number in dovecot before handing off the authentication to the radius server? I want the usernames on the mail server to remain first initial + last name. I don't mind maintaining a mapping file to go from username to employee number because I can automate this task. Has anybody done this?
