[Dovecot] Weirdness with authentication/1.0a4.
by Ashley Penney 27 Oct '05

27 Oct '05

Hi, FreeBSD has recently upgraded their port from 0.99 to 1.0a4, and this has caused me an absolute nightmare of a situation. In a nutshell I replaced my conf with the -example, and modified almost nothing. I made some SSL certs and put them in place, left it with imap/pop/pam etc. Whenever users tried to connect to the remote address, cara.untaken.net, I would get: Oct 27 18:31:14 cara dovecot: Dovecot v1.0.alpha4 starting up Oct 27 18:31:33 cara dovecot: imap-login: Login failed: Plaintext authentication disabled: rip=217.206.62.50, lip=217.206.62.50 Oct 27 18:31:33 cara dovecot: imap-login: Disconnected: rip=217.206.62.50, lip=2 17.206.62.50 However, plaintext authenication was most definitely not disabled. Using www.untaken.net/mail/ which is hosted on the same box as dovecot I could get this plaintext failure constantly using cara.untaken.net, but switching to 'localhost' instead would work fine, despite being the same physical machine. I'm baffled at what could cause this, I put my currently conf over at www.untaken.net/dovecot/ just for reference, I've modified various bits now from the default in a desperate attempt to get it working. Has anyone else seen anything like it? -- <EisernLint> i am considering taking pilates classes.

[Dovecot] Authentication using native MySQL PASSWORD() function
by Tom Sommer 27 Oct '05

27 Oct '05

Hi, I have a little problem, I need to adapt a setup that currently uses the native MySQL PASSWORD() function to encrypt passwords for e-mail accounts. I plan on using Dovecot with SQL to authenticate on my server, is there a password scheme that fits this authentication method? Any help is appreciated -- Tom Sommer

[Dovecot] Shared Folder usage alpha3
by Ralf Zerres 27 Oct '05

27 Oct '05

Dear List, this is my first mail to this list. I'v tried to carefully review all given information towards the Shared Folder subject I could find in the archive / mailing list / wiki. And so far I'm also aware that Timo hasn't put it on the active tasklist for the 1.0 release. Citing the track http://dovecot.org/pipermail/dovecot/2003-October/002493.html I was wandering, wether any further attempt has been made, to use the given functionality for real work. To be more precise, wether anybody has done - delivery of mailboxes to a shared maildir - offering these maildirs through a given namespace Before bothering here without any local experience, I'v set up a dov-server (1.0alpha3) on a debian sid. As an MTA postfix is doing the job. Within postfix I did set up a virtual domain and the needed maps (mailbox, alias). I'm able to deliver successful with the standard postfix functionality to the given filesystem structure (fs=ext3). If it is on any help, I can post the relevant config files. As good practice, all mail is delivered to given mailbox-owner with 0600 permission for the new subdir. Hence, can't be seen by any shared-maildir user (unless owner uid matches:) >From here on I'v tried to switch from debians default postfix delivery-strategy (mailbox_command = procmail -a "$EXTENSION") to given dovcot deliver process (mailbox_command = /usr/lib/dovecot/deliver). The primary aim is to define a strategy to deliver with 0660 rights which will enable group read-write access to the given Mailstore. I have adopted the dovecot.conf enableing a listening socket ... default_mail_env = maildir:/home/%u/Maildir: \ INDEX=/home/%u/MaildirIndex namespace private { separator = / prefix = inbox = yes } namespace public { # the prefix needs to be postponed with the separator prefix = Public/ # the location path given as [<mailbox-type>:]<path>/mailbox location = maildir:/home/SharedMaildirs separator = / inbox = no hidden = no } auth default { ... # using deliver through a socket socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } } and configured the subsequent dovecot-deliver.conf ... auth_socket_path = /var/run/dovecot/auth-master mail = maildir:%h/Maildir/ umask = 0007 auth_verbose = yes use_syslog = yes just to see, whether a manual call /usr/lib/dovecot/dovecot-deliver -d <user> <testmail would do the trick. Well, I got the delivered mail, but files are not installed with the etimated previledges. Can someone can point me to the clou? Greetings Ralf PS: I also read about posix-acl's support. But my test's didn't allow a successful read ....

[Dovecot] Alpha4 pre-release, please upgrade
by Timo Sirainen 27 Oct '05

27 Oct '05

Please try if http://dovecot.org/nightly/dovecot-latest.tar.gz (or the CVS directly) works with you. I made a lot of changes to dovecot-auth, so I wouldn't want to make alpha4 release without some more testing in different environments. I'll release alpha4 in a few days, but it'll be basically same as this unless more bugs get fixed. Some of the changes include: - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication.

It's possible to have an auth order so if the first is true skip the other ones? Bye Rick

[Dovecot] pop3 behaviour
by Krzysztof Janiszewski - IT Partner 27 Oct '05

27 Oct '05

Hi! I'v installed dovecot over um-pop3 today. Dovecot has only pop3 enabled. imap will be enabled later. But there is one issue - on some accounts, after receiving mail to Outlook Express, mail is not deleted from /var/mail/username mbox file, and on most it is deleted. Why it works in that way? Best regards Krzysztof

[Dovecot] 1.0alpha4: mbox-lock asserts and cores
by Jeff A. Earickson 27 Oct '05

27 Oct '05

Timo, I upgraded from alpha3 to alpha4 yesterday, and I am seeing a few of the following asserts: imap(user): file mbox-lock.c: line 379 (mbox_lock_fcntl): assertion failed: (lock_type == F_UNLCK) Gdb info on a couple of the cores is attached. It looks like the arg lock_type for mbox_lock_fcntl() is not getting passed in correctly, like the enum "enum mbox_lock_type type" in mbox_lock_list() is not getting set or used correctly so that lock_data[type].func is wrong. Hmmm. My setup: Solaris 9, mbox, dovecot built with gcc 4.0.2. The filesystem for INBOXes is NFS mounted from another Solaris 9 system, but the index files reside on local filesystems. My setting for "lock_method = fcntl", per your release notes. I did not change the default setting of "mmap_disable = no" because my index files are local. Jeff Earickson Colby College
