[Dovecot] Trying to use "deliver" as a LDA
by Stéphane Legrand 10 Oct '06

10 Oct '06

Hello, I'm trying to use "deliver" as a LDA for some users. I found the page http://wiki.dovecot.org/LDA where i read that i can use the ".forward" file in the user HOME directory. However, when i try, i get the following error in the maillog file : ... deliver(...): mbox: We need root IMAP folder, but can't find it or HOME environment ...deliver(...): Failed to create storage for 'user' with mail 'mbox:/var/mail/user' where "user" is the user login. How can i fix this error ? My aim by using "deliver" as a LDA is to force a quota for the mailbox user. Is this the right thing to do to achieve this ? My configuration is the following : OS : FreeBSD 6.1 Dovecot 1.0.r7 Thank you for your help.

[Dovecot] (mail_cache_add): assertion
by Daniel Voelkel 09 Oct '06

09 Oct '06

Hi, I currently use rc2 on FreeBSD AMD64. Are there any news regarding this Bug: mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size)? I read that access to an 64bit-machine could help you. Feel free to contact me. Greetings from germany, Daniel -- GMX DSL-Flatrate 0,- Euro* - Überall, wo DSL verfügbar ist!

[Dovecot] RFC compliance on folder lists
by Tony Kay 09 Oct '06

09 Oct '06

If a mail folder contains quotes, the IMAP server may respond with a line like: 1 list "" "a/b/"X" Y Z" The specific example I saw had this exact form (it was in a nested folder, and one of the words was quoted). -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Physics is like sex: sure, it may give some practical results, but that's not why we do it. - Richard Feynman

[Dovecot] fix: LDA logging
by David Lee 09 Oct '06

09 Oct '06

Timo: As discussed over the last couple of days. Please could the attached patch be applied to "deliver.c" so that it can log (syslog etc.) final delivery into the destination mailbox. This completes a hitherto missing part in logging an email's progress; it is useful (for example) to diagnose "my email wasn't delivered" problems. Thanks. -- : David Lee I.T.

[Dovecot] dovecot, procmail and deliver
by David Lee 09 Oct '06

09 Oct '06

(Using dovecot 1.0 RC7 on Fedora Core 5) <scene set> Hitherto we have used UW-IMAP on a "farm" of Linux machines mounting NFS from a NetApp. (The UW-IMAP author doesn't like use of NFS, but with careful use of NFS mount arguments ('noac,actimeo=0' etc.) and trying to ensure that all activity for a given user takes place within one machine in the farm, we seem to have been OK.) We have also used UW-IMAP's 'tmail' (in sendmail.cf) and 'dmail' (from any user procmail recipes), so that access to the INBOX has been consistently UW-IMAP software. We are now considering doing a transparent migration to dovecot to improve performance. </scene> --- First: a general question: To complement the UW->dovecot migration of the IMAP daemon (reading the INBOX and folders), ought I to do a similar delivery-side migration from [UW] tmail/dmail to [dovecot] 'deliver'? It would feel safer this way, but maybe I worry too much... --- Second: "deliver" seems to add an unconditional "From " line at the start of each delivery. From sendmail, using the 'n' flag, "Mlocal F=...n..." that is OK. (Although I'm not convinced that "dovecot.deliver", nor its two-space separator (emphasis on "two") from the following date are ideal. Nor, come to that line's lack of "@somewhere".) But from a procmail recipe, I end up with two "From " lines. Surely this is incorrect. How can this be reduced to one? Shouldn't "deliver" ensure that there is only "From " line? --- Third: Would it be possible for "deliver" to do a "syslog" entry to confirm final delivery into the destination mailbox, please? (I could try and produce a patch, but someone else with more dovecot familiarity could probably do the job must more quickly and probably also more cleanly!) (I think that's all for the moment.) -- : David Lee I.T.

[Dovecot] patch: mailboxcasecmp()
by Frank Cusack 09 Oct '06

09 Oct '06

Here is a patch which adds mailboxcmp() and mailboxcasecmp() functions, similar to mailbox_equals(). Names were chosen to match strcmp() and strcasecmp(). I needed this for Johaness Berg's dspam plugin. It watches a folder "SPAM" and forcing this to be uppercase is unacceptable for me. (I also had to modify the plugin to use the new routine.) It's against dovecot-1.0.beta8 but should be trivial to port to CVS. -frank

We converted from uw-imapd to dovecot but are still having problems with MBX mail folders. The user can't access this "MBX mail folder": [root@volt Resume's]# file "Sys Admin" Sys Admin: MBX mail folder [root@volt Resume's]# mailutil copy ./"Sys Admin" '#driver.unix/new' Can't open mailbox ./Sys Admin: no such mailbox [root@volt Resume's]# mailutil copy -debug -verbose./SysAdminSave '#driver.unix/new' Can't open mailbox ./SysAdminSave: no such mailbox Could you tell me what I am doing wrong?
