[Dovecot] Please help me resolve why mail isn't being delivered to virtual users
by Andrew Falanga 12 Jan '08

12 Jan '08

Hi, I have to admit that I'm not quite sure why no one has responded to me about this one. If I'm not providing enough information or incorrect information please tell me. It's quite important that this e-mail system be working. I do not quite understand what it is that I'm missing now. I have the need to setup and configure various users as virtual users. To this end, I've configured them so that their home directories are "/virtusers/<userid>" and their INBOXes are "/var/mail/<userid>." I have created a system user ID called "vmail" which is referenced in my PostgreSQL database for UID/GID stuff. All virtual user home directories and INBOXes are made owner "vmail" and group is "users." Originally, I had my sendmail "/etc/mail/aliases" file setup to "map" all mail sent to these virtual users to the system user "vmail." However, none of the virtual users were getting any mail and vmail was just getting swamped. After doing more digging, I found that I just didn't understand the home directories and INBOX, mbox and such. That's what drove me to configuring what's in there now. Now, following directions on this WIKI page: http://wiki.dovecot.org/LDA/Sendmail?highlight=%28deliver%29 I'm still unable to get the e-mail working for them. Continually, sendmail bails with errors saying it, "Can't create output." Because I am using *.mc files, I made a new *.m4 file as directed in /usr/share/sendmail/cf/mailer. Dovecot does allow the virtual users to login. In fact, when I did, the first time, there appears a "mail" directory in their home directories after login. This would indicate to me that the login was successful. Further, I cut/pasted a message sent to one of the virtual users from the vmail INBOX (/var/mail/vmail) into the virtual user's INBOX (/var/mail/jdunkin). Then, logged in as this virtual user and ACTUALLY got the mail. I know this stuff works. What must be done to make sendmail do its thing for deliver? What is necessary to fix this situation? Andy

[Dovecot] Allow_nets

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I use the allow_nets password extra field [0] for my users. Is there a way to use this functionality for ALL users, and not to edit my passwd-file every time a new user is added ? The alternative i am working for this is the TCP Wrappers.

[Dovecot] Dovecot-imap, tls, gnus
by Richard G Riley 11 Jan '08

11 Jan '08

I have a connection to my dovecot server from gnus: ,---- | (add-to-list 'gnus-secondary-select-methods | '(nnimap "hermes" | (nnimap-stream starttls) | (nnimap-address "hermes") | (nnimap-authinfo-file "~/.authinfo"))) `---- If I enter a group and read my mail then wander off and come back after a few minutes I can not navigate out of the group because my nnimap session has ended. What config parameter do I need to change in Dovecot to keep it open for the life of the client? (I am assuming its a dovecot issue here since it didn't happen with courier-imap).

[Dovecot] Problem: "Missing IMAP reply key: F"
by Claus Atzenbeck 11 Jan '08

11 Jan '08

Hi all: I installed dovecot v1.0 (on Mac OS X) and want to connect to is on localhost via Pine or Alpine, but it fails. Pine's debug mode tells me the following: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Debug output of the Pine program (debug=2 debug_imap=4). Version 4.64 (OSX) [...] Terminal type: screen About to open folder "INBOX" inbox is: "INBOX" IMAP 14:40:22 1/11 mm_log babble: Trying IP address [::1] IMAP 14:40:22 1/11 mm_log warning: Connection failed to localhost,143: Connection refused IMAP 14:40:22 1/11 mm_log babble: Trying IP address [127.0.0.1] IMAP DEBUG 14:40:22 1/11: F IMAP 14:40:22 1/11 mm_notify warning: {localhost}inbox: Missing IMAP reply key: F IMAP 14:40:22 1/11 mm_notify bye: {localhost}inbox: [CLOSED] IMAP connection broken (server response) IMAP 14:40:22 1/11 mm_log error: [CLOSED] IMAP connection broken (server response) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I use the options "disable_plaintext_auth = no" and "ssl_disable = yes", because I don't need encryption. (I only access the server from localhost.) What does "Missing IMAP reply key: F" mean? Any easy way to solve the problem? Thanks for any hint! Claus

[Dovecot] Automatically subscribe to folder?
by Christian Flothmann 11 Jan '08

11 Jan '08

Hello everybody, i am filtering e-mails using the cmusieve-plugin. A global script filters all mails tagged by SpamAssasin and moves them into the folder Spam: if header :is "X-Spam-Flag" "YES" { fileinto "Spam"; } My problem is that users who did not had a folder Spam until the first time of filtering a spam mail are not automatically subscribed to this new created folder. They have to do this step manually in their mail client. Is it possible to automate this script and subscribe the account to this folder when it is created by the sieve script? Regards, Christian

[Dovecot] Test Environment Question
by Stewart Dean 11 Jan '08

11 Jan '08

I have my master IMAP server running DC V1.0.10. The homedir and INBOXdir are physically resident there and NFS exported (no caching) to 3 other machines. I have installed V1.1beta13 on one of them (which thus accesses the homedir/INBOXdir remotely) and plan to have a limited community test-drive it there. Are there any hazards or drawbacks in doing this? While the homedirs and INBOXdirs are thus shared, I have it so that each machine has its own local index directory and /var/run dir. Comments or dire warnings?

Ok, did that. And looking at all the alerts it appears to be any file that deliver is trying to write under /home/vmail. My users are all virtual and they all exist like: /home/vmail/example.com/john typical permissions: -rw------- 1 vmail vmail 464 2008-01-01 20:06 dovecot.index.log but for some reason even though deliver is setup to run as vmail:vmail it is still having permission problems. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${recipient} ????

[Dovecot] [dovecot][configure] docdir option lost
by Guth 11 Jan '08

11 Jan '08

Hi, While building dovecot-1.0.10 i've a trouble with --docdir configure option. It seems this option overload is "lost" during makefiles recurse generation (i didn't check others overload). Following are config.log and Makefiles cuts : ------------------- $ grep docdir dovecot-1.0.10/config.log dovecot-1.0.10/Makefile dovecot-1.0.10/doc/Makefile dovecot-1.0.10/doc/wiki/Makefile dovecot-1.0.10/config.log: $ ./configure --prefix=/usr --with-gssapi --with-ldap --with-sql --with-mysql --sysconfdir=/etc --localstatedir=/var --mandir=/usr/man --with-docs --docdir=/usr/doc/dovecot-1.0.10 dovecot-1.0.10/config.log:docdir='/usr/doc/dovecot-1.0.10' dovecot-1.0.10/Makefile:docdir = /usr/doc/dovecot-1.0.10 dovecot-1.0.10/doc/Makefile:docdir = $(datadir)/doc/dovecot dovecot-1.0.10/doc/wiki/Makefile:docdir = $(datadir)/doc/dovecot ------------------- I'll correct it in a dirty way (sed is my friend after Makefiles creation) because i want it built quickly, but i guess it shouldn't be hard to avoid this problem in futures releases. -- Guth

[Dovecot] virtual domains/users and LDAP
by Anil 11 Jan '08

11 Jan '08

I have two suffixes in LDAP with users, e.g. ou=People, o=example.com ou=People, o=somethingelse.com I have the following two users: dn: uid=test1, ou=People, o=example.com uid: test1 mail: test(a)gmail.com dn: uid=test2, ou=People, o=somethingelse.com mail: test(a)yahoo.com uid: test2 The users login to IMAP as: test1(a)examle.com and test2(a)somethingelse.com. Here's an (excerpt) of the dovecot.conf file I am using: auth_bind = yes base = ou=People,o=%d scope = onelevel pass_attrs = mail=user pass_filter = (uid=%n) userdb static { args = uid=vmail gid=vmail home=/var/mail/apps/%d/%n } The problem I am seeing when the user logs in, the home dir is getting created incorrectly: Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] imap-login: Login: user=<test(a)gmail.com>, method=PLAIN, rip=, lip= Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): Effective uid=500, gid=500, home=/var/mail/apps/gmail.com/test Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): maildir: data=/var/mail/apps/gmail.com/test/Maildir ... I was expecting it to create the home dir under: /var/mail/apps/example.com/test1, since that is what they are logging in with. Any ideas? I am actually surprised that it even let me login with this configuration, something looks odd in this setup. :) Thanks, Anil
