[Dovecot] Password environment variable - logging the password
by Donovan Craig 04 Jun '09

04 Jun '09

Hi, We¹re migrating to a Cpanel hosting system. Our passwords are currently stored in MD5. I looked at the post login scripting to be able to start storing the plain text passwords as people login temporarily so we can automate our migration. It seems that the password is not available in the post login environment variables. Is there any way we can get access to the plain text password upon login so we can insert this into our user table? Best regards, Donovan

[Dovecot] Some questions about deliver
by Axel Luttgens 04 Jun '09

04 Jun '09

While investigating Dovecot's deliver with Postfix, I encountered some behaviors making me wonder whether I really understand the purpose of that binary. So, if you allow... This is from Postfix' main.cf: mailbox_command = /usr/local/dovecot/libexec/dovecot/deliver -e -n This is my quick setup for Dovecot: # 1.2.rc4: /usr/local/etc/dovecot.conf # OS: Darwin 9.7.0 i386 protocols: pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3- login first_valid_uid: 2001 mail_location: mbox:~/_mailboxes:INBOX=~/_inbox/mailspool mbox_read_locks: flock mbox_write_locks: flock dotlock mail_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/dovecot-1.2.rc4/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xv%08Xu auth default: passdb: driver: pam args: * userdb: driver: passwd Here is an excerpt from mail.log: postfix/smtpd[4117]: connect from localhost[127.0.0.1] postfix/smtpd[4117]: 163E1CA2675: client=localhost[127.0.0.1] postfix/cleanup[4120]: 163E1CA2675: message-id=<27002A3F-AF44-410D-A500-368D04F5FA9A(a)almbp.local > postfix/qmgr[3232]: 163E1CA2675: from=<testuser(a)almbp.local>, size=2650, nrcpt=1 (queue active) dovecot[4129]: deliver(www): mail_location: mbox: mkdir(/Library/ WebServer/_mailboxes) failed: Permission denied (euid=70(_www) egid=70(_www) missing +w perm: /Library/WebServer) dovecot[4129]: deliver(www): Fatal: Namespace initialization failed postfix/local[4122]: 163E1CA2675: to=<www(a)almbp.local>, relay=local, delay=0.09, delays=0.02/0/0/0.07, dsn=4.3.0, status=deferred (temporary failure) postfix/smtpd[4117]: disconnect from localhost[127.0.0.1] 1. Shouldn't deliver honor the first_valid_uid setting? After all, if some user isn't allowed to login, is that user supposed to receive mail? 2. What exactly is the -e option supposed to do? User _www clearly isn't configured for receiving mail, but Postfix will nevertheless try to deliver the message until maximal_queue_lifetime has expired. From the log excerpt, it appears that Postfix has been led to consider a temporary failure; unless I'm wrong, that's because Postfix didn't receive neither a "D.S.N text" string nor an EX_* fatal return code. From deliver.c, it seems that many calls to i_fatal() are liable to be executed before the -e option is taken into account (through the local variable stderr_rejection). As a result, I'm wondering under which circumstances exactly deliver is liable to return EX_NOPERM, so that Postfix may consider a permanent failure and bounce the message. Note that the question may somehow be re-phrased as: when invoked without the -e option, under which circumstances will deliver send a rejection message? 3. Doesn't failure_exit_callback() in deliver.c tend to merge many (possibly dissimilar) errors into the single EX_TEMPFAIL one? And BTW, is that function guaranteed to be always called with an EX_* value? Seems to be the case, but... ;-) TIA for your patience, Axel

[Dovecot] Help please- Post - Login Script--- Migration
by Ashraf 04 Jun '09

04 Jun '09

Hi all I am in the process of migrating Courier to Dovecot, am using courier-dovecot-migrate.pl<http://www.dovecot.org/tools/courier-dovecot-migrate.pl>it works fine. I want to migrate each user as they login using post-login script (As i have huge no of users). We are using NFS storage, users are authenticated using mysql, User home directories as passed using variable mail ( usign mysql query). I am trying to execute postlogin script which does the conversion but unable to pass the user home directories . --*/etc/dovecot.conf mail_executable = /usr/libexec/dovecot/postloginscript.sh %h ---* %h ---- for home directory. ---*postloginscript.sh #!/bin/sh /usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot --recursive --convert $1 # This is for pop3 exec /usr/libexec/dovecot/pop3 ----* When i pass %h as argument its creating "%h" directory and writing dovecot-uidlist and rest the files in %h directory. Its not interpreting the %h and not passing the home directory. Its just passing as it is. Hope i am clear in articulating my problem. Please help. -- Regards Ash

[Dovecot] system accepts my domains without point
by Esteban Torres Rodriguez 03 Jun '09

03 Jun '09

I have postfix+ dovecot + ldap (AD). my system accepts user@domain as user@domain. as user(a)domain.com. To send as much to create the mailbox when I login to squirrelmail, for example. Problem is postfix, dovecot or from AD? Someone can help me? -- ################################################## # Esteban Torres Rodríguez # # Área de Soporte Técnico # # Subdirección de Sistemas Informáticos # # Empresa Pública Desarrollo Agrario y Pesquero # # email: etorres(a)dap.es # ##################################################

Hello, > The patch shouldn't really have changed anything. > >> in 1.1.16 it works without the patch. > > And I didn't fix anything in 1.1.16 either. Maybe it was some weird > compiling issue or something.. i do not have an explanation, but effect is the same. i repackaged 1.1.15 with and without patch and only the one with the patch works. for 1.1.16 i do not need a patch. gcc is 4.1.2 but its not important for me, just some tests...

[Dovecot] 1.2.beta1: expire-tool and 'mail_location' setting
by e-frog 03 Jun '09

03 Jun '09

Hi Timo, Trying 1.2.beta1 with expire plugin currently: When I set mail_location = maildir:~/.maildir the expire plugin doesn't delete messages. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: no messages left I also noticed that above command creates a new but empty directory 'mail' in user's home dir. However using mail_location = maildir:~/Maildir and of course moving the messages to it works. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: seq=1 uid=4078: Expunge . . Info: foo/Trash: seq=100 uid=4178: Expunge Info: foo/Trash: seq=101 uid=4179: Expunge Info: foo/Trash: timestamp 1235292536 -> 1235325429 My guess is that mail_location is not respected by expire-tool for some reason and in second case mailbox auto-detection makes it working?

[Dovecot] expire tool - individual user/folder?
by Andre Hübner 02 Jun '09

02 Jun '09

Hello, is the expire plugin usable to delete mails with different settings for each individual user? If i view sample config at http://wiki.dovecot.org/Plugins/Expire it looks like expire-data are related to foldernames. Is it possible to let each user "activate" the expire-plugin for different folders with different settings? Thanks, Andre
