[Dovecot] SASL und APOP
by Luca Bertoncello 14 Feb '06

14 Feb '06

Hi, all! I configured Dovecot to use many protocols. To do this, I wrote: mechanisms = plain digest-md5 cram-md5 apop ntlm Very strange, if I ask the capability, I get: CAPA TOP UIDL RESP-CODES PIPELINING STLS USER SASL PLAIN DIGEST-MD5 CRAM-MD5 NTLM . I can't understand why APOP is not written (but I can use it!) and why I can see SASL, that I didn't configure... How can I change these message so that I get PLAIN APOP DIGEST-MD5 CRAM-MD5 NTLM? Thanks a lot! -- _______________________________ Luca Bertoncello -Programmierung / Mailserver- IMS Internet-Media-Service GmbH Bärensteiner Straße 7 01277 Dresden Fon: +49 351 2112034 Fax: +49 351 2112020 email: bertoncello(a)internet24.de

[Dovecot] Message index corruption when using Thunderbird and Dovecot
by Reuben Pearse 14 Feb '06

14 Feb '06

Hi all, I have recently upgraded from UW-IMAP to Dovecot 1.0.beta3 on Redhat9. I migrated my mailbox to from Mbox to Maildir using the mb2md perl script, and created a procmail recipe file to get email arriving in the Maildir directories. However, when accessing my mailbox from Thunderbird (version 1.5), it occasionally mixes up the email header with the email content. I also occasionally get errors like this when clicking on old messages (ones that got converted as part of the mb2md script). The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' in '<16384.-15744>' However, if I click on the email item again, Thunderbird is then able to retrieve the message correctly. Can anyone provide some help with these problem.

[Dovecot] Re: Mail.app help
by Roger Weeks 14 Feb '06

14 Feb '06

I'm wondering if this is a version issue with Mail.app? Are you on OS X 10.3 or 10.4? The reason I ask is that we also migrated from Courier IMAP to Dovecot 1.0alpha5 and then beta3, and we did not have this problem with Mail.app that either of you are describing. I did have to remove the "INBOX." prefix from my Mail.app configurations. I also renamed all of the existing folders in my Maildir from INBOX.foldername to .foldername, because after removing the "INBOX." prefix Mail.app could not see them. Before I renamed all of the existing folders and changed the prefix in Mail.app, I had also tried setting up alternate namespaces as described in the wiki documentation for converting from Courier, but that did not seem to work. Mail.app and Thunderbird clients could not see their IMAP folders with the courier-style namespace configuration. -- Roger J.

[Dovecot] Dovecot-1.0.beta1: New mail sometimes fails to appear
by Tom Alsberg 14 Feb '06

14 Feb '06

Hi there... Having updated to 1.0.beta1, I for a while thought a bad bug with IDLE handling that caused new mail in INBOX not to appear when using Mozilla Thunderbird has been solved. Although I can not reproduce one kind of problem anymore, after a short while it again appears that one does not always see one's new mail with Thunderbird. I can not consistently reproduce the bug, but from some network captures it indeed appears that sometimes Thunderbird has (in one of its connections to the server) INBOX SELECTed and IDLE on it, new mail arrives, but 10 minutes afterwards it was still not sent an EXISTS message. Initially the symptoms appeared to suggest that something really bad happened to the index files, but I tried INDEX=MEMORY and that did not help much. Thunderbird using multiple connections to the server does of course only make debugging more difficult. But it appears that without multiple connections, one has to constantly cycle around SELECTing to get notified on more than one mailbox, so that may justified. I am a bit lost on this now, and would appreciate some ideas. Although there were several related bugs I noticed in Thunderbird 1.0, it appears that they are gone in 1.5, and yet now it really seems Dovecot is doing something wrong here. Attached is the configuration file I use for the testing installation of Dovecot 1.0.beta1 (somebody tell me if you see something wrong there). The mailbox arrangement is as follows, right now (until we have a better way): * INBOX in /var/mail/%u * most mailboxes in ~/imap.maildir/... as maildirs. * mboxes in ~/imap.mbox/... accessible as #imap.mbox/... * the mbox:~/mail/ is for when namespaces are not used - now there are so it should not be relevant Except for myself, and one test account I have, I have two guinea-pigs using it (who are well aware that it is still under development and that it will break once in a while) and reporting problems to me. Vaguely (since I can't figure the exact reasons), the symptom can be described as follows: When using Mozilla Thunderbird to access mail, new mail arrives to INBOX (mbox:/var/mail/%u), but is sometimes not seen for a long while after it arrives. Sometimes the first (or first few) message arriving appears, but then no new messages appear, and sometimes everything works right and immediately new mail is seen. However whenever (according to Thunderbird) something changes in the mailbox, the mailbox is seen up-to-date as it really was at that time.

[Dovecot] Mail.app help
by Mike Garfias 14 Feb '06

14 Feb '06

I'm having a problem with Mail.app and imap folders. I've got a new install of dovecot 1.0beta2, and am only experiencing this problem with Mail. Mutt works as expected, as well as thunderbird. When I create a folder using Mail.app, it is written to ~/Maildir/.INBOX.newfolder, which would be fine, if I wasn't telling everything that I wanted no prefixes. If I move that folder to ~/Maildir/.newfolder, Mail.app can no longer see it, but mutt and thunderbird can. Thunderbird _CAN_ see the folders created as .INBOX.Folder, and even shows it as a subfolder of my inbox, but Mutt completely refuses to see it. Any ideas what I'm doing wrong here?

[Dovecot] passwd-file

Hi, the wiki doesn't explain the file format for passwd-file. I want to do a small set of virtual users using flat files. I have my postfix "vmailbox" generated, and working as expected for delivery. I've configured dovecot, put passwd-file for the auth_passdb, and specified a file name. By "passwd like" what is allowed? Where is it document. How unlike passwd can it be? Must I read the source code? Simon

[Dovecot] nologin
by Robert A. Thompson 14 Feb '06

14 Feb '06

I need to be able to setup a nologin system for users on my mail server on a per user basis. We are going to do some maintenance on each user (individually) and would like it if they could not login to dovecot while we do this. I was curious if dovecot implemented anything like this. We are currently using standard pam authentication (nothing db related) and I was hoping to be able to touch a "nologin" file on a per user basis in their home directory. I think I could do this with some pam magic, but was curious if dovecot had something in it that would allow for this. Note: I understand I will have to forcibly kill active connections. --Robert
