[Dovecot] Cooperating with dovecot in its Maildir
by Rob Browning 29 Jan '11

29 Jan '11

Is it possible to cooperate with dovecot within its Maildir, and if so, what's required? In this particular case, we're thinking of trying to allow notmuch to operate directly on the dovecot Maildir, and at the moment, the only modifications notmuch makes are to change maildir flags. Would locking dovecot-uidlist.lock be sufficient, perhaps via liblockfile? Also, is there some reliable way to detect a dovecot Maildir? For example, are any of the dovecot-* files guaranteed to exist all the time?

[Dovecot] How do I do this with mdbox?
by Odhiambo Washington 29 Jan '11

29 Jan '11

In my life with Maildir, mails were stored as single files, each mail per file. It was pretty easy to resend an e-mail from a Maildir folder to another address, by causing the mail to be re-injected into my MTA (Exim) queue for processing: I'd use a very simple shell script to achieve the above: #!/bin/sh email=$(find $*) { for x in ${email}; do sendmail president(a)egypt.gov < ${x}; done } Now, with mdbox container/storage, it beats me how to achieve the same. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Sharing user folders doesn't work when users have periods in names.
by ian+dovecot＠comtek.co.uk 28 Jan '11

28 Jan '11

I am using period as an IMAP separator with Maildir directories and I cannot share folders where the user has a period in their name. Suppose I log in as 'some.user' and do: SETACL INBOX mailtest(a)example.co.uk +lrwstipekxacd /var/mail/virtual/users/some.user/Maildir/dovecot-acl is created, with appropriate contents and shared-mailboxes.db gains an entry for 'shared/shared-boxes/user/mailtest@example.co.uk/some.user@example.co.uk'. mailtest is simply unable to see a new folder. As mailtest 'a LIST "" "Users.*" ' is empty. If I do ' a MYRIGHTS Users.some.user.INBOX ' I get 'NO [NONEXISTENT] Mailbox doesn't exist: Users.some.user.INBOX' and, oddly, a new maildir appears: '* LIST (\Noselect \HasChildren) "." "Users.some" ' -- it also creates an empty folder structure with a single file /var/mail/virtual/users/some/Maildir/dovecot-acl-list too! Is there a workaround that does not involve rebuilding every user's Maildir with backslash as a separator? Thanks, Ian

[Dovecot] Dovecot2 + Sieve
by Philipp v. Strobl-Albeg 28 Jan '11

Hi, i'm new on sieve, but want to use ist with sogo. The Problem is, that when i set a redirect or vacation rule like: redirect "email(a)example.com"; (real Adress is different) the sieve says the mail would be forwarded, but no mail is sent. (No Action in /var/log/maillog) And because there is no Error-Message it's difficult to search for... Dovecot log ------- Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: using sieve path for user's script: /var/mail/vhosts/test/.dovecot.sieve Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: opening script /var/mail/vhosts/test/.dovecot.sieve Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: script binary /var/mail/vhosts/test/.dovecot.svbin successfully loaded Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: binary save: not saving binary /var/mail/vhosts/test/.dovecot.svbin, because it is already stored Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Debug: sieve: executing script from /var/mail/vhosts/test/.dovecot.svbin Jan 28 10:53:46 lda(ptest(a)pilarkto.com): Info: sieve: msgid=<4D429227.3000004(a)pilarkto.net>: forwarded to <email(a)example.com> ----- Everything else works fine, except the program "mail". I dont know if there is a coherence but a typical Mailserver-Test "date|mail -s test email(a)example.com" also don't sent a message to postfix. I hope you will held me out or even say me, if this is a bug or a misconfiguration. thanks a lot Philipp

[Dovecot] dovecot ACL
by PA 28 Jan '11

28 Jan '11

Hi in Dovecot 2.x with virtual domains, is there a way specify what domains can create shared directories and who can't? For example I have 3 domains, domain1.com, domain2.com and domain3.com. Let's say I only want domain1.com's users to create shared folders how can I go about doing this. Thanks, Paul

[Dovecot] Telnet access creates new maildir folders
by Seasoul 28 Jan '11

28 Jan '11

Hi, I am running Dovecot Version 1.0.15on a Debian server, with postfix and postfixadmin. My mailbox base is /var/mail/vmail When I send an email to a user1(a)domain.com for the first time, the user "mail" creates a set of dovecot folders under /var/mail/vmail/ user1(a)domain.com/ and my new emails are found in /var/mail/vmail/ user1(a)domain.com/new When I test my server using telnet (telnet domain.com 110), I can log in fine as a user1, but when I type "LIST", it tells me there are no emails. And I realize a new set of dovecot folders were created under /var/mail/vmail/user1/ ! The folders are created by the user "user1". Obviously the folder "new" under that is empty, since my emails received are in /var/mail/vmail/user1(a)domain.com/new and not /var/mail/vmail/user1/new . Therefore, connecting with an email client via POP also shows an empty inbox. I am lost as to what to do to fix this, and how to let the server know that pop access should be looking into /var/mail/vmail/user1(a)domain.com/ instead of /var/mail/vmail/user1/ . Hopefully someone on this list will be able to save me from my misery :) Cheers Sea

[Dovecot] Best way to calculate concurrent users?
by Henrique Fernandes 28 Jan '11

28 Jan '11

Well, i am having some problens to figure out how many concurrent users into the server! In my envoriment now, most people are using the webmail interface, and it just conect and disconct pretty quickly so i can not get it with "doveadm who" doveadm who only gets the ones that are connect with clients. O use ipvs to balance betwaeen 2 servers does anyone have an ideia ? With ipvs i get this results: IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP XXX.XX.X.XX:143 lblcr -> 10.0.2.10:143 Masq 1 16 228 -> 10.0.2.11:143 Masq 1 16 184 There is others ports and stuff. Does any one have an ideia how to get this number ? []'sf.rique

[Dovecot] Storing Dovecot index files on sql
by list＠airstreamcomm.net 28 Jan '11

28 Jan '11

We have been communicating with the mailling list on another thread regarding dotlocking on the dovcot-uidlist over an NFS share, and I was hoping to get some ideas on whether or not a sql database would be a suitable location for storing the dovecot index files. Our though process so far has been that storing the index files on NFS with the maildir has not worked very effectively when we are using multiple Dovecot servers (even using sticky IPs in our load balancer), and using local storage is not possible with a cluster of machines, so we got to thinking about what type of storage platform would be suitable for these index files that would provide native locking of the data while multiple servers accessed and wrote to it. Our question to the community is whether sql storage for index files has ever been considered, what issues would this introduce, and if it's even feasible? Thanks everyone! Michael
