[Dovecot] IMAP subfolders and MBOX format
by Frank Bonnet 14 May '09

14 May '09

Hello folks I have a problem related to the mbox format I think First we use MBOX format with Dovecot 1.14 A user's here need to create some subfolders in his Imap space. Due to the use of MBOX format this is impossible from thunderbird as you cannot creat a directory in a file :-) So to help him I created manually on the mail server some directories into his imap space, Doing so we are able to see the folder and subfolders but it is not possible to move some other folders into the subfolder via the thunderdird client. Anyone to help me a bit ? Note : on another machine which use the Maildir format I can do whatever I want without problem. Thanks a lot.

[Dovecot] id:N13388 Disable storage of messages on server when read (pop3)
by Dimitrios Karapiperis 14 May '09

14 May '09

Hi there Is there any way in dovecot to disable the storage of messages on server when they are read/downloaded by the users (POP3). The server keeps the e-mail when users tick the option on their MUA to keep (leave) messages on server. dovecot 1.0.7 POP3 / maildir Thanks in advance Dimitrios Karapiperis postmaster [at] thessaloniki [dot] gr

[Dovecot] What's faster for getting mails into Rails: Dbmail & direct MySQL or net/pop with maildir
by Olaf Spaarmann 14 May '09

14 May '09

Hi, it's my first message in this list, so please excuse any mistakes! I have a quite specific problem and nobody in the Ruby on Rails lists could help me, because it is actually more a question for mail- experts. So I hope you can help me. I'm planning to set up a mailserver using dovecot. Users of my Rails App can forward their emails (john(a)doe.com) to an personal address (john.doe(a)myapp.com ). These emails will be received by my mailserver. So far so good, the tricky part is to get the mails into my Rails App for processing them. After that they will be deleted (so I'll never accumulate a big ammount of mails on the mailserver). I thought of 2 different approaches. 1) Just use a normal Dovecot setup, using maildir and get the mails with a mailpoller script, connecting to the server via Pop3 2) Use Dbmail for storing the emails, don't use Pop3 but let the mailpoller script connect to the database directly I understand that Dbmail seems to be slower than maildir (in terms of processing many incoming mails) but I'm not sure if a connection via net/pop (of the mailpoller script) is maybe that much slower than mysql that it wouldn't matter at all. What's your opinion? I'm gratefull for every hint. Thanks

[Dovecot] X-UIDL Ignored?
by Benjamin Wakefield 14 May '09

14 May '09

Hello! I am trying to migrate from Teapop to Dovecot. I'm using Dovecot 1.1.14. I need to make use of the X-UIDL header so clients don't download messages they've already received. I have the X-UIDL head in the message. I have pop3_reuse_xuidl(pop3): yes My problem is the X-UIDL in the message is being ignored and Dovecot is still generating it's own. The INBOX is an mbx file not Maildir. Should this work? Have I missed something? Thanks!

[Dovecot] virtual mailbox users users can send, but can't read e-mail
by Ioan Nemes 13 May '09

Greetings, I am trying to add the second virtual mailbox domain (transco.org.au) to an existing Postfix/Dovecot/MySQL mail server. Users of the first virtual mailbox domain (transylvania.org.au) have no problems sending and receiving mail. Users belonging to the second virtual mailbox domain can successfully send mail to outside, however they won't receive the mail, though Postfix delivers the mail to the mail directories.

[Dovecot] Dovecot 1.0.7 domain variable
by elliott＠n.localhost 13 May '09

13 May '09

Hi all, Thanks in advance for any help! I'm trying to configure Dovecot to pull emails from Postfix virtual mailbox domain Maildirs under /var/mail/vhosts/<domain>/<username>. I've set mail_location as such in dovecot.conf: mail_location = maildir:/var/mail/vhosts/%d/%n but from debug output I see the domain is blank: dovecot: May 10 20:49:25 Info: IMAP(elliott): maildir: data=/var/mail/vhosts//elliott I've set elliott(a)n.0o0.bz as my username in Outlook so it is sending the domain (and changed auth_username_format to "auth_username_format = %n" so authentication works fine) Why is %d blank here? Anything else to check?? I'm at a loss. Thanks! -elliott-

[Dovecot] Dovecot shared quota with Maildir
by Jorgen Lundman 13 May '09

13 May '09

Hello list, We are in the process of exploring the idea of moving from UFS with fs-quota to using softquotas in Dovecot (probably Maildir type, stored in LDAP, all ontop of NFS). I have it setup, and it works rather well so far. But there is one situation we can currently support, which I can not see a solution for with soft-quotas. Generally customers get 1 email, with 1 quota. But it is also possible for customers to get 1 quota, but create multiple mail accounts, all sharing the same quota. This is done by using the same UID for each account when using fs-quota. (It is not that each account gets a fraction of the quota, but that all accounts add up to the one quota). Is this still possible to do with soft-quotas. To share one set. Dovecot would have to go count files in multiple mail-directories so I would guess no.

[Dovecot] dovecot bug (maybe)

I believe that dovecot is doing something strange, when it founds a 'corrupted' multipart and using fetch body. Look what I figured out: 1) Sent a message from squirrelmail (it wrongly drop the last \n from epilogue): ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n <--------(squirrelmail didn´t insert an additional \n). ------=_20090512171902_78105-- 2) Sent a correct message, inserting the last '\n': ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105-- 3) Compress both messages 4) Request the messages using: A004 UID FETCH 1 (FLAGS BODYSTRUCTURE) (the correct message): 127.000.000.001.00143-127.000.000.001.35604: * 1 FETCH (UID 1 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *3 1*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171853_50085") NIL NIL NIL)) A004 OK Fetch completed. 5) Request the broken message: 127.000.000.001.00143-127.000.000.001.43679: * 2 FETCH (UID 2 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *1 0*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171902_78105") NIL NIL NIL)) A004 OK Fetch completed. >From RFC the red numbers mean: size body, number of line for the body. This makes sense, because stripping the 'control' chars from first message, size and number of lines match. But in the second message, the line number is 0 - this does not make sense. You need to test this using telnet, because outlook and thunderbird did not follow this way, they use body.peek. What do you think? Fernando
