[Dovecot] dovecot + sendmail, what LDA setup?
by David Cake 05 Jan '11

05 Jan '11

I have an existing setup with sendmail, dovecot, on debian. I want to move LDA and move from using mbox to using Maildir. I have only 'real' users and aliases, no virtual users. What is a recommended, trouble free, LDA setup? procmail is of course on possibility, but I'd be unlikely ever to use any of its advanced features, just simple local mail delivery. I'd like to use deliver, but most of the dovecot as LDA sample configs I have seen seem to assume I am using it for virtual users. Advice? Pointers to a simple working setup for sendmail, dovecot, Maildir? Cheers David

[Dovecot] re-indexing moved mail
by Phil Howard 05 Jan '11

05 Jan '11

I have a huge block of email that was misdelivered into the wrong folder. Moving it where it should be is not just all from one folder to being all of another folder. Basically, the index files need to be rebuilt. Looking in the wiki I cannot find how to do this. It all seems to be about installation, and no administrative tools. Or would it be just as simple as delete certain index files and they would be automagically rebuilt? -- sHiFt HaPpEnS!

[Dovecot] Error copying >1 message to virtual mailbox
by Nicholas Riley 05 Jan '11

05 Jan '11

I created a virtual mailbox which maps to a single physical mailbox (in Dovecot 1.x I did this with a symlink but had intermittent problems with Dovecot 2.0 doing the same.) However, I can only copy one message at a time into the mailbox. If I try to copy more, I get: 7.16 UID COPY 48531:48532 !/Saved 7.16 NO [CANNOT] Can't save messages to this virtual mailbox whereas this works fine: 10.16 UID COPY 48531 !/Saved 10.16 OK Copy completed. The dovecot-virtual file in !/Saved is: !2011-01 all and dovecot.conf: # 2.0.8 (cde0d403c6ff): /etc/dovecot/dovecot.conf # OS: Linux 2.6.18.8-linode22 i686 Debian 5.0.7 mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX:CONTROL=~/.dovecot.cont rol:SUBSCRIPTIONS=.subscriptions mail_max_userip_connections = 20 namespace { inbox = yes location = prefix = separator = / } namespace { location = virtual:~/Maildir/! prefix = !/ separator = / } passdb { driver = pam } plugin { antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_spam_pattern_ignorecase = *spam } protocols = imap ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " virtual" } Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Converting from Maildir - sdbox
by Marc Perkel 04 Jan '11

04 Jan '11

OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location = maildir:/vhome/%d/home/%n:INDEX=/imap-cache/%d-%n I don't have any namespace setting. Not quite sure what a namespace is or why I need one. This is what I'm trying to run: dsync -u marc(a)perkel.com backup sdbox:/email/%d/home/%n What I'm hoping to do is do a mass conversion while running. Then shut it down - do a second quick pass - and bring it up in sdbox format. Thanks in advance.

[Dovecot] dovecotpw missing (2.0.8)
by Kristina Clair 04 Jan '11

04 Jan '11

Hello, I just installed dovecot version 2.0.8 from the source tarball. After doing ./configure, make, and make install, I don't have the dovecotpw binary anywhere. It is not in /usr/local/bin or /usr/local/sbin where the other binaries are; I also did a find / for it and don't see it. Is there some configuration flag I'm missing? I read the flags in ./configure --help and nothing seems obviously applicable to me. Is there a cryptography library I could be missing? I have the libs installed for crypt, md5, etc. Thanks, Kristina

[Dovecot] namespaces and noselect
by Kyle Wheeler 04 Jan '11

04 Jan '11

Hello, I am trying to use two namespaces to create an "archival" directory that is stored as mboxes (the rest of my tree is all stored as maildirs). However, when I add the second namespace, suddenly Dovecot starts emitting, in response to the LIST command, a second version of the INBOX that is marked as \NoSelect. Here are my namespac definitions... am I doing this wrong? namespace { list = yes hidden = no inbox = yes location = maildir:~/Maildir prefix = separator = / type = private } namespace { hidden = yes # do not list as a separate namespace list = no # inbox = no location = mbox:~/Maildir/Archive:LAYOUT=fs:INDEX=~/Maildir/ArchiveIndexes/ prefix = INBOX/Archive/ separator = / type = private } ~Kyle -- If you are going through hell, keep going. -- Winston Churchill

[Dovecot] Implications of zlib plugin on search operations
by Ralf Hildebrandt 04 Jan '11

04 Jan '11

Right now I'm compressing all mails older than 31 days and larger than 100k in size. But what implications does this compression have on search queries performed by users (user looking for an old mail containing a certain string). -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Finally upgrading from v1.0.15 to v1.2.16 -- advice please
by Jan-Frode Myklebust 04 Jan '11

04 Jan '11

It's long over due, but now I finally plan on upgrading from v1.0.15 to v1.2.16 on our servers. Would appreciate any comments! We have 7 servers, all running of the same GPFS filesystem. Both maildirs and indexes are stored here. We use dovecot for POP/IMAP and deliver. Currently we're using mysql as authentication source, but want to move to using ldap instead. Can we upgrade one server at a time, or do we need to upgrade all servers at the same time ? http://wiki2.dovecot.org/Upgrading/1.1 says "Index files have slightly changed as well. Upgrading to v1.1 should go transparently, but moving back to v1.0 might again cause some errors." which makes me think we can't have both versions running against the same users ? Also, if we upgrade only one server, should we switch to "mmap_disable=no" on this one, or keep running with "mmap_disable=yes" on all servers ? "NFS users should now set mail_nfs_storage=yes and mail_nfs_index=yes." Does this apply to any shared/networked filesystems, and is this relevant for GPFS ? The sql queries we're doing now is: password_query = select U.Account as user,S.Password as password from Users U, UserSession S where U.Account=S.Account and U.Account='%u' user_query = SELECT 3000 as uid, 3000 as gid, concat(concat('maildir:', MailDir), concat(':INDEX=', replace(MailDir, '/usr/local/atmail/users', '/usr/local/atmail/users/indexes'))) as mail, concat('maildir:storage=', UserQuota) as quota FROM Users WHERE Account = '%u' I plan on doing ldap bind() for authentication: hosts = maildb3.example.net:389 auth_bind = yes ldap_version = 3 base = ou=people,o=%d,o=ISP,o=example,c=net deref = never scope = onelevel user_filter = (&(objectClass=altiboxperson)(uid=%n)) default_pass_scheme = SSHA but the user_query is a challenge.. In LDAP we have: uid = janfrode, ou=people,o=domain1.net,o=ISP,o=example,c=net mail = janfrode(a)domain1.net mailMessageStore = /usr/local/atmail/users/j/a/janfrode(a)domain1.net mailQuota = 1000000 domain = domain1.net userPassword = SSHA-string So, outside of the user_attrs we need: mail_uid = 3000 mail_gid = 3000 But I'm having a hard time understanding how I can use the ldap value mail=/usr/local/atmail/users/j/a/janfrode(a)domain1.net to translate into dovecot's "mail" containing both "maildir:" and "INDEX=". Does the below look correct ? user_attrs = mailMessageStore=mail=maildir:%$:INDEX=/usr/local/atmail/users/indexes/%1u/%1.1u/%u, mailQuota=quota_rule=*:storage=%$ i.e. will it point dovecot at: mail = maildir:/usr/local/atmail/users/j/a/janfrode@domain1.net:INDEX=/usr/local/atmail/users/indexes/j/a/janfrode@domain1.net quota_rule=*:storage=1000000 -jf
