Dear Sir, Thanks for your reply and I really agreed your point about 'reject mail for users over quota', but I don't want to do it if it is possible to without reject mails to deliver mails from spool to user's home directory automatically, kindly provide solution.

[Dovecot] FOSDEM
by Timo Sirainen 25 Jan '12

25 Jan '12

I'll be in FOSDEM giving a small lightning talk about Dovecot: http://fosdem.org/2012/schedule/event/dovecot I'll also be around in FOSDEM the whole time, so if you're there and want to talk to me about anything, send me an email at some point. Poll to dovecot-news list people: Do you want to see these kind of news about my upcoming talks sent to the list? Probably happens a few times/year. A simple "yes" or "no" reply to this mail privately to me is enough.

[Dovecot] Dovecot antispam plugint got an empty message
by Petr Bravenec 25 Jan '12

25 Jan '12

Few weeks ago I upgraded dovecot from 1.2 to 2.0.16 and antispam plugin to 2.0_pre20101222. Since the upgrade I'm not able to move messages to my Junk folder. In the maillog I have found this message: dspam[25060]: empty message (no data received) Message is copied from my INBOX to Junk folder, but dspam got an empty message and sent an error return code. So the moving operation is not successfull and the original message in INBOX was not deleted. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin. Can you help me, please? Petr Bravenec

Hi, I am using dovecot 2.0.16, and assigend globally procmailrc (/etc/procmailrc) which delivers mails to user's home directory in maildir formate. Also I assined quota to User through setquota (edquota) command, If the quota excedded then this case user's mail store to /var/spool/mail/user. After incresing quota how to delivered these mails to user's home dir in maildir formate automatically.

[Dovecot] Imap Quota Exceeded - But Still Receiving Emails?
by Palatine Web Support 25 Jan '12

25 Jan '12

Hello I am trying to setup dovecot maildir quota, but even though it seems to be working fine, I am still receiving emails into my inbox even though I have exceeded my quota. Here is my dovecot config: plugin { quota = maildir:User Quota quota_rule2 = Trash:storage=+100M } And my SQL config file for Dovecot (dovecot-sql.conf): user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 8 AS gid, CONCAT('*:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' CONCAT('*:storage=', quota) AS quota_rule quota_rule = *:storage=3M So it picks up my set quota of 3MB but dovecot is not rejecting emails if I am over my quota. Can anyone help? Thanks. Carl

Re: [Dovecot] change smtp port

They will *always* use port 25 and nothing else. If your problem is that your Internet Service Provider is blocking port 25, you can contact them. Some ISPs will unblock port 25 on request, or might even have an online form you can fill out. If you can't get help from the ISP, you need a remailer service -- some outside proxy that accepts the mail for you and forwards connections to some different port on your computer. I don't know of any free services that do this; dyndns and others offer this for a fee, sometimes combined with spam/virus filtering. -- Noel Jones

And I though that I can stop using port > 25 as it's not always working from ISP As I said, you obviously do not understand how smtp works. This is made obvious by your questions, and failure to understand that port 25 is *the* port for receiving email on the public internet. Period. If your main problem with port 25 is *sending* (relaying outbound) mails, then you will need to take this up with your ISP. If they are unable or unwilling to address the problem, one option would be to setup your system to relay through some other smtp relay service on the internet using port 587 as you apparently read somwehere, but you don't do this by changing the main smtpd daemon to port 587, because as you discovered, you won't be able to receive *any* emails like this. That said, I fail to see any relevance to dovecot in this thread... -- Best regards, Charles

[Dovecot] Trying to get metadata plugin working
by Thomas Koch 24 Jan '12

24 Jan '12

Hi, I'm working on a Kolab related project and wanted to use dovecot on my dev machine. However I'm stuck with the metadata-plugin. I "solved" the permissions problems but now I get dict: Error: file dict commit: file_dotlock_open(~/Maildir/shared-metadata) failed: No such file or directory Before that, I had dict { metadata = file:/var/lib/dovecot/shared-metadata but got problems since my normal user had no permission to access /var/lib/dovecot. I compiled the plugin from the most recent commit. My dovecot runs in a chroot. I can login with KMail and can create Groupware (annotated) folders, but the metadata file dict won't get created and I also can't set/get metadata via telnet. doveconf -N # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 3.1.0-1-amd64 x86_64 Debian 6.0.3 auth_mechanisms = plain dict { metadata = file:~/Maildir/shared-metadata } mail_access_groups = dovecot mail_location = maildir:~/Maildir mail_plugins = " metadata" passdb { driver = pam } plugin { metadata_dict = proxy::metadata } protocols = " imap" service dict { unix_listener dict { group = dovecot mode = 0666 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " metadata imap_metadata imap_annotatemore" } Best regards, Thomas Koch, http://www.koch.ro
