Hi, you have written in your Dovecot 2.2.5 - Changelog that you have solved a Problem with pop3. *· pop3: Avoid assert-crash if client disconnects during LIST.* My question is: Is it possible to get this problem with my version? 1.2.17 ? Thanks

[Dovecot] Delivering message to other mailbox
by Frank de Bot 20 Aug '13

20 Aug '13

Hi, On my mailserver I have for each mailbox a sieve script to put Spam-marked message into a folder (match header, then fileinto 'Spam'). This works, but I want to deliver spam-marked messages to a different mailbox. For each user a seperate mailbox is created next to the existing mailbox, allowing different authentication. How can I do this with dovecot/pigeonhole? I figured out I could redirect is the user.spam@domain which delivers to the other mailbox, but it will go into a new delivery process with amavis set up. (There's no point to scan a single message twice). Is there a way I can accomplish to directly deliver a spam-marked message to a different mailbox? Regards, Frank de Bot

[Dovecot] Using procmail to mark messages as read in dovecot
by LuKreme 20 Aug '13

20 Aug '13

So, I use procmail extensively, and I have for a long time, but marking messages as 'read' in a Maildir has always been a little wonky: TRAP='mv "$LASTFOLDER" "${LASTFOLDER}:2,S"' Since I've switched to dovecot, is there a way to mark a message on delivery as read or not new or seen? -- Clarke's Law: Sufficiently advanced technology is indistinguishable from magic

[Dovecot] age-limit
by Carlos L 20 Aug '13

20 Aug '13

I'm trying to figure if there is a "proactive" way to enforce item age on maildir . maildir-cleanup kind of does it but im looking for something similiar to quota ++ that you can add to dovecot but for item age not size. Any ideas?

All of a sudden I am getting these errors on one of my accounts: imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10) It was working fine last night when I went to bed, and is posting these errors nearly constantly (about one every second) when I checked mail after waking up this morning. The account is question is my main account and has a lot of mail, but it is not the account with the most mailboxes, that one is working fine. I looked at the documentation on how to increase this setting, but <http://wiki.dovecot.org/MainConfig> is for 1.x and clicking the 'wiki2" link brings up a mostly blank page with no configuration info at all. It looks like in dovecot 1.x this would go in an protocol imap block, but I don't have one of those in my conf. # doveconf -n # 2.2.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE i386 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 89 log_path = /var/log/dovecot mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox NotJunk { auto = subscribe } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } -- 'Never trust a ruler who puts his faith in tunnels and bunkers and escape routes.

[Dovecot] Calling dovecot-lda correctly from exim for virtual user setup
by Frerich Raabe 20 Aug '13

Hi, I'm running Dovecot 2.1.7 on Debian. Exim is the MTA. I was recently made aware of the fact that the way in which Exim invokes dovecot-lda is prone to code injection: dovecot_virtual_delivery: driver = pipe command = HOME=/home/vmail/\$local_part /usr/lib/dovecot/dovecot-lda -f \$sender_address use_shell .. I.e. a command is executed via the shell, and Exim uses non-sanitized user input (mail header fields) to construct the command. Now, the reason I invoked dovecot like that is to pass a plausible value for the HOME environment variable, so that dovecot-lda can determine where the Maildir directory of the recipient is. Is there any way to achieve this without requiring HOME to be set correctly? I looked at the -m switch but as far as I can see that merely defines the destination mailbox, but not the path to the Maildir directory, correct? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing
