[Dovecot] data corruption in delivery agent when forwarding
by Joshua Goodall 19 Jul '06

19 Jul '06

Hi Timo I've been seeing data corruption in the lda when forwarding mail. I think it's due to confused file pointers. (this is all maildirs on nfs) Anyway the following patch fixes it, and also looks a bit more like the old dovecot-lda module, by getting the Return-Path header before getting the input stream: Index: mail-send.c =================================================================== RCS file: /home/cvs/dovecot/src/deliver/mail-send.c,v retrieving revision 1.1.2.1 diff -u -r1.1.2.1 mail-send.c --- mail-send.c 11 Jun 2006 11:10:55 -0000 1.1.2.1 +++ mail-send.c 19 Jul 2006 09:28:18 -0000 @@ -116,16 +116,17 @@ struct smtp_client *smtp_client; FILE *f; const unsigned char *data; + const char *return_path; size_t size; int ret; + return_path = mail_get_first_header(mail, "Return-Path"); + input = mail_get_stream(mail, NULL, NULL); if (input == NULL) return -1; - smtp_client = smtp_client_open(forwardto, - mail_get_first_header(mail, "Return-Path"), - &f); + smtp_client = smtp_client_open(forwardto, return_path, &f); input = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, hide_headers, best regards as ever /k -- Josh "Koshua" Goodall "as modern as tomorrow afternoon" joshua(a)roughtrade.net - FW109

[Dovecot] strange dropping of Word.doc-attachements - sendmail dovecot RHEL4
by Götz Reinicke 19 Jul '06

19 Jul '06

Hi, we have a strange problem: two of our users informed me, that they aren't able to send word-.doc-files anymore while othe attachements work fine. The e-mail gets deliverd, but the attachement is dropped. This happens using the latest thunderbird 1.5.x and mac os x. The e-mail is also not saved in the send-drawer. If the users send the same e-mail to the same recepient using an other mailclient, there is no problem. Other users (like me) using the same systemsettings and software versions don't have the problem. The server is RHEL 4 (2.6.9-kernel), sendmail 8.13.1 and dovecot 0.99. We use Mailscanner and spamassassin too, but as only the two users do have the problem I'm looking for some help to track this problem down. Any ideas??

Are you using procmail? If yes, something may be breaking it. Apostolis Papagiannakis

by Philipe Gaspar 18 Jul '06

18 Jul '06

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues,

[Dovecot] Masking INBOX.INBOX
by Ben Schumacher 18 Jul '06

18 Jul '06

I am using dovecot and trying to make it compatible with my a BincIMAP installation. BincIMAP uses a scheme similar to Courier-IMAP, so I set up this default_mail_env: default_mail_env = maildir:~/Maildir And this namespace: namespace private { separator = . prefix = INBOX. inbox = yes } Which mostly works as expected, but I now see an "INBOX" subfolder of "INBOX" in LIST: * OK Dovecot ready. 1 login ben ******** 1 OK Logged in. 2 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.INBOX" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasChildren) "." "INBOX.Jabber" * LIST (\HasChildren) "." "INBOX.Keepers" * LIST (\HasChildren) "." "INBOX.Ruby" * LIST (\HasNoChildren) "." "INBOX.Trash" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "." "INBOX.Spam" * LIST (\HasNoChildren) "." "INBOX.postmaster" * LIST (\HasNoChildren) "." "INBOX.qmail" * LIST (\HasNoChildren) "." "INBOX.Jabber.XMPPWG" * LIST (\HasNoChildren) "." "INBOX.Jabber.standards-jig" * LIST (\HasNoChildren) "." "INBOX.Keepers.2003" * LIST (\HasNoChildren) "." "INBOX.Keepers.2004" * LIST (\HasNoChildren) "." "INBOX.Keepers.2005" * LIST (\HasNoChildren) "." "INBOX.Ruby.ruby-talk" 2 OK List completed. Is there anyway to mask this from displaying? I've toyed with various configurations to try to hide it, but nothing seems to work. What's annoying is this situation: 3 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Drafts" 3 OK Lsub completed. 4 SUBSCRIBE "INBOX" 4 OK Subscribe completed. 5 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.INBOX" 5 OK Lsub completed. Note that in my first LSUB the main "INBOX" isn't subscribed to. I then "SUBSCRIBE" in 4 to "INBOX" and dovecot translates that to subscribing to "INBOX.INBOX". Not a huge deal, but it does cause Thunderbird to act weirdly (although Thunderbird allows me to UNSUBSCRIBE to "INBOX" and still get new mail), but I'm not sure what the effect will be on other clients. Any ideas? Thanks, Ben

[Dovecot] (un)selectable folders
by Francisco Isgleas 18 Jul '06

18 Jul '06

Hi ya'll I'm using dovecot 0.99.11 and I have a doubt about some folders. The Inbox folder is greyed out on most of my clients, and I just cannot move any message (on other folders) into inbox. I'd like to know if I can do that. Besides that, when I select the Drafts folder I get the "Mailbox isn't selectable" warning, and cannot save any drafts there so, how could I change that? Thnx -- NaCl+U2 @O2 Franscsi Isgleas

[Dovecot] Getting maildir++ quotas working
by Bill Boebel 18 Jul '06

18 Jul '06

Can somebody post details for how to get maildir++ quotas working in the latest CVS? I have tried but can't get the CAPABILITY string to show "QUOTA"; and the GETQUOTAROOT command is recognized, but returns nothing... 2 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "" * QUOTA "" () 2 OK Getquotaroot completed. These are the settings I have... am I missing something? protocol imap { mail_plugins = imap_quota quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir imap_quota = maildir } Here are some more details: Dovecot is creating the maildirsize file in my maidir, and it seems to show correct storage used calculations, but the first line which should contain my storage limits is blank. So I suspect that I am not returning a valid quota value from the user database. I am returning what my old Courier-IMAP wants to see "1073741824S,4000C"... if the format for Dovecot is different, what should the format be? So there are two problems that I am trying to resolve, but I'm not sure how to go about fixing it. Any help would be greatly appreciated: (1) Dovecot isn't announcing QUOTA support in the capability string. (2) Dovecot isn't getting a valid quota limit, which I assume is breaking the GETQUOTAROOT command. Thanks, Bill

[Dovecot] Empty messages in 1.0RC2
by Renaud Allard 18 Jul '06

18 Jul '06

Hello, I am running 1.0RC2 (upgrade from a beta, so I haven't tested RC1 unfortunately). I sometimes get empty messages in my inbox folder. Mails are stored using Maildir. Here is an output of a ls -la ~/Maildir/cur -rw------- 1 n users 0 Jul 18 09:31 _CFC+Y5IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:28 _bEG+A2IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:54 _ezF+eOJvEB.gandalf.llorien.org:2, -rw------- 1 n users 2246 Jul 18 08:10 msg.f23:2,RSa There is one real message (the last one). All messages seems to have strange file names names, even the real one. Messages delivered by the MTA generally have a name like 1152736772.H956194P17632.mail.llorien.org:2,RS There is nothing in the SMTP server logs that could suggest these empty mails are delivered with SMTP and only dovecot version has changed. So I guess this is dovecot related. My IMAP client is thunderbird on Linux, but I have also seen the problem with sylpheed on OpenBSD. Any help or hint appreciated.
