[Dovecot] Weird behaviour with multiple accounts pointing to same maildir
by Bill Moran 17 Sep '04

17 Sep '04

I'm finding this a little strange. I'm putting together a mail server that will (someday, hopefully) serve a lot of email addresses for a lot of domains. To make life easy, each account name is the full mail name ... i.e "joe(a)domain.com" instead of just "joe" Mail is stored in Maildirs, and the user account information is all in MySQL. Delivery is handled by Postfix. Everything seems nice and clean, except ... If I create multiple accounts that all use the same Maildir for delivery (i.e. joe_smith(a)domain.com, js(a)domain.com, js(a)otherdomain.com) it seems to work well. Except that the user can _only_ log in as the first record in the database via IMAP. (i.e. in the example above, the user could log in as joe_smith(a)domain.com, but not the others) Logging in as the others does not produce any erros (that I can find, anyway) but the user can't see his/her mail. I'm rather stumped as to why this is happening. Each record in the database that points to a particular Maildir is identical except for the userid. In the example above, logging in as the 2nd or 3rd account shows folders created, but not the mail in them. For example, the above db records would look like: +----------------------+----------+-----------------------------+-----+-----+--------+ | userid | password | home | uid | gid | active | +----------------------+----------+-----------------------------+-----+-----+--------+ | joe_smith(a)domain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | | js(a)domain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | | js(a)otherdomain.com | ???????? | /mail/domain.com/joe_smith/ | 125 | 125 | Y | I'm assuming this is some sort of bug, but if I'm wrong, please correct me. Any ideas? Using Dovecot dovecot-0.99.10.9 on FreeBSD 4.10, talking to mysql-server-4.0.20. -- Bill Moran Potential Technologies http://www.potentialtech.com

[Dovecot] FreeBSD port of Dovecot
by Viren Patel 17 Sep '04

17 Sep '04

Hello. I am trying to install Dovecot 0.99.10.9 on a FreeBSD 4.10 system from the ports collection (latest via cvsup). When running make, I get the message: dovecot-0.99.10.9 Currently incompatible with security/gnutls This is in contrast to the Dovecot web page which states that it does support GNUtls and OpenSSL. I am not really interested in gnutls/openssl support at this time. Is there a way I can install this port without gnutls/openssl?. My apologies if this is not the appropriate forum but I couldn't find info. on the port maintainer. Thanks. V. Patel Chemistry & Biochemistry University of Texas at Austin

[Dovecot] Logging IMAP transactions
by Kenneth Porter 17 Sep '04

17 Sep '04

Mulberry has the ability to log the IMAP exchange client-side. Is there an equivalent logging feature in Dovecot (0.99) to log the IMAP exchange server-side? My problem is that Mulberry is displaying some complex MIME structures incorrectly (eg. nested/forwarded messages) but it seems to go away if I close a folder and re-open it. I'm suspecting that Dovecot is reporting the wrong structure on first access and then fixes something on subsequent accesses. I'd like to log the FETCH result with the structure information to see if I can spot this happening.

[Dovecot] Fedora Core 2, dovecot, and Outlook Express
by Joe Hartford 14 Sep '04

14 Sep '04

After the aging harddrive in my Redhat 7.2 server died, I decided it was time to upgrade. I bought a new harddrive and did a fresh install of Fedora Core 2. I've managed to get www, ssh and sendmail reconfigured, but I'm having a heck of a time with imap. I first fooled around with cyrus-imapd, and couldn't make head or tail of it, so I downloaded a fedore core 1 imapd rpm and installed it. That almost worked, but I could only see the INBOX. Next I tried dovecot. Via Outlook Express from my winXP box, I can Refresh the IMAP folder list, and see the INBOX and the sent-mail and saved-messages folders that were created when I first ran pine. However, if I try and mark sent-mail or saved-messages as Visible, I get an "Invalid mailbox name: saved-message/" error. And when I try and view the contents of Inbox, I get "Mailbox doesn't exist: INBOX/". I tried running evolution on the server, and I could subscribe and view the INBOX. But when I try and make a new folder, it gives me a "Cannot create the specified folder. Generic error" I'm hoping I just have something misconfigured, potential due to messing around with cyrus-imapd and imapd, or perhaps even pine. Anyone have any suggestions? I'm pretty close to giving up on fedora core 2 and installing core 1, or perhaps mandrake. --Joe Hartford

Well, could you attach gdb into the process while it's running and get backtrace? ie.: gdb /usr/local/libexec/dovecot/imap pid bt

[Dovecot] ok, one last time with mbox vs. maildir
by Brian Hechinger 13 Sep '04

13 Sep '04

i'd *really* like to get to maildir. so here it is, one last time.... using 0.99.x, can i have an mbox spool file and Maildir folders? for just one account? if i can do that, then it'll be a lot easier to transition the whole mess to Maildir. i use procmail called from postfix to deliver mail. is that going to be an issue for delivery? if i don't set DEFAULT and just change all my sort rules to deliver to Maildir folders then i can have it continue to deliver mbox to the inbox-spool and Maildir to the folders? -brian -- "The cats tend to administer themselves, and contrary to the expected facts, the house and everything in it was installed for their benefit." -- Nic Clews

[Dovecot] duplicate message headers in Thunderbird with dovecot server
by Matt McClure 13 Sep '04

13 Sep '04

I've been trying to diagnose some strange interaction between dovecot and Mozilla Thunderbird. If two clients are connected to a dovecot IMAP server, Mozilla-based clients start showing multiple messages in the message list for each message that arrives after the sessions were started. There is really only one copy of the message in the mbox file on the server. However, its UID changes repeatedly during the session, and Mozilla gets confused. From looking at Thunderbird's log of the IMAP conversation, it seems the message sequence number does not change, and I'm guessing that other clients handle the situation better because of this. Nevertheless, I found this in the IMAP RFC 3501, so my interpretation is that there is a dovecot bug involved: The unique identifier of a message MUST NOT change during the session, and SHOULD NOT change between sessions. Any change of unique identifiers between sessions MUST be detectable using the UIDVALIDITY mechanism discussed below. Persistent unique identifiers are required for a client to resynchronize its state from a previous session with the server (e.g., disconnected or offline access clients); this is discussed further in [IMAP-DISC]. Has anyone else experienced this problem? Is there a known solution? I've been logging what I've found so far at http://bugzilla.mozilla.org/show_bug.cgi?id=209561 -- Matt Funky like your grandpa's drawers

[Dovecot] 0.99 mail env
by Curtis Maloney 13 Sep '04

13 Sep '04

Greetings, all Last night I migrated our mail between two machines... both running dovecot 0.99.xx. In the process, I wanted to make some small changes, namely that new mail be delivered to mboxs in /var/mail/%u and IMAP mail stored in Maildirs at ~/.imap ... I tried using: default_mail_env = maildir:~/.imap/:INBOX=mbox:/var/mail/%u But had no luck. Is it only 1.0 that can work with two different mailbox formats? Or did I screw up somewhere else? In the end, it actualy saved me a fair bit of work, since I'd have had to move everyone's old inbox. -- Curtis Maloney cmaloney(a)cardgate.net
