I though I was replying to the whole ml. Apparently the ml is not very well configured because a reply does not reply to the whole ml, but to the single sender.

I was using the RoundCube web client on my server and had no such message. It was just telling me that it could not move the message. I configured a Thunderbird then and it displayed indeed this message 'Failed to call dspam'. So I made your trick, I compiled myself the dovecot-antispam library and now I can move messages... But are you sure that it is the right method and that the dspam training is indeed called? Because if I read well this piece of code, it looks like it was checking if the dspam training was successful. We commented out this check, so now maybe it fails and we copy the messages anyway to Junk/ even though no training really occurred. And when I check the logs or the dspam_stats, I don't see any change, even though I guess this retraining should be seen as a change in the stats, no? > > Antispam plugin is easy to understand: when you configure antispam_spam > = SPAM it will set SPAM folder as his special folder to observe.

By the way, when one has the item "X-DSPAM-Result: Innocent" in the header, it means the email is not a spam, does'nt it (right now I am focusing on having this plugin working for training purpose, but currently not much is working perfectly as expected in my email spam system)? > > You can provide some info from your log files, i'll try to help.

[Dovecot] Permission denied problems

04 Feb '09

Hi. I'm trying to configure Dovecot for Vpopmail. The authentication works good, but I have some "permission denied" error when I try to open the IMAP folders: dovecot: 2009-02-03 19:16:08 Info: imap-login: Login: user=<test(a)testdomain.com>, method=PLAIN, rip=192.168.246.45, lip=172.16.4.106, TLS dovecot: 2009-02-03 19:16:09 Error: IMAP(prova(a)tuttoenumero.it): stat(/home/vpopmail/domains/testdomain.com/test/Maildir/cur) failed: Permission denied This is my dovecot.conf: protocols = imap imaps disable_plaintext_auth = no log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = IMAP server ready. mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir mail_privileged_group = vchkpw mail_access_groups = vchkpw mail_debug = yes mmap_disable = yes (my maildirs are on a NFS filesystem) first_valid_uid = 89 last_valid_uid = 89 first_valid_gid = 89 last_valid_gid = 89 auth_verbose = yes auth_debug = yes auth default { passdb vpopmail { } userdb passwd { } userdb static { args = uid=89 gid=89 mail=Maildir:/home/vpopmail/domains/% } userdb vpopmail { } user = vpopmail } The /home/vpopmail/domains directory and subdirectories are owned by vpopmail.vchkpw and with the permissions 700. The user vpopmail can access to /home/vpopmail/domains/testdomain.conf without any problem. Could you help me to find the problem, please? Thank you very much! Bye.

[Dovecot] Latest CentOS rpms.
by Roderick A. Anderson 03 Feb '09

03 Feb '09

Along with my post about authentication I was wondering if anyone was building RPMs for the later versions of dovecot (and postfix) than I can find in the usual and not-so-usual yum repos? I already pull from rpmforge but would prefer something later than 1.0.7 Say the 1.1 series. Thanks, Rod --

[Dovecot] Dovecot on Mac - Entourage cannot fetch emails
by Bijo 03 Feb '09

03 Feb '09

Hi, Dovecot 1.1.3 is running on Mac OS X 10.5 latest version, with Maildir (LAYOUT=fs). I have following issues when Entourage 2008 connects it, over imap/imaps. Entourage does not cache the mails. After every restart the folder contents are fetched fresh. I have enabled the Entourage option to get entire messages. Entourage caches the gmail IMAP folders fine. Also Outlook 2007 does not have this problem while connecting to the same IMAP server. I have some big folders with a few thousands of emails. Entourage fails with Error: 4362 (Mail could not be retrieved this time) while fetching mails from these folders. Restarting and rebuilding the Entourage database did not fix this issue. Any tips to resolve these issues or to debug what is going on would be greatly appreciated. Thanks, Bijoy -- View this message in context: http://www.nabble.com/Dovecot-on-Mac---Entourage-cannot-fetch-emails-tp2175… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 1.1.10 and chroot
by Michal Soltys 03 Feb '09

03 Feb '09

As it's been a while since I upgraded (1.1rc10, jump to 1.1.10), this might be present in earlier versions as well. Anyway, if one enables mail_chroot in global config file, dovecot will try to access /tmp there. Per-user overrides behave correctly. For example, with: mail_chroot=/home/vmail dovecot will abort with: Fatal: chdir(/home/vmail/tmp) failed with uid 65534: No such file or directory Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf

[Dovecot] Dovecot-antispam does not work
by Jehan Pagès 03 Feb '09

03 Feb '09

Hi, I have installed dovecot-antispam and configured it this way (as in the doc) with the dspam exe: protocol imap { mail_plugins = antispam mail_plugin_dir = /usr/lib64/dovecot/imap } plugin { # For dovecot-antispam: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items antispam_spam = SPAM;Junk #antispam_unsure = unsure antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --deliver=;--user;%u antispam_mail_tmpdir = /tmp } But it does not work and really I cannot figure it out for two days, because I can find no log wherever, where it writes it does (or try to do) something, nor in the dovecot logs, nor in the dspam logs. But I know something is happening because when I try to move a spam from my inbox to the Junk folder, it fails with an error telling it could not move the email. At the opposite, when I deactivate the antispam plugin, I can move normally the emails. So what could I do to fix my issue or at least diagnose it (where would I find logs of what is happening?)? Thanks. Jehan
