[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?

[Dovecot] Maximum number of connections from user+IP exceeded
by LuKreme 20 Aug '13

20 Aug '13

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

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

Re: [Dovecot] Dovecot + SELinux permission problems

Typically you could use "sealert -a /var/log/audit/audit.log /var/log/audit/audit.log.1" to get a feel for how many SELinux exceptions are happening. Also, when you say that the restorecon -R did not fix the issue, did you check the output of "ls -Z" after running it? However, looking at your original message, I'm wondering why the forward slashes are doubled up. For instance: "/home/user/data1/Maildir//"

[Dovecot] Disagreement on where mail goes.
by LuKreme 19 Aug '13

19 Aug '13

My virtual users have their mail stored in /usr/local/virtual/user(a)example.com/ dovecot wants to read the mail from /usr/local/virtual/user(a)example.com/Maildir which is causing problems since all new mail is being written in /usr/local/virtual/user(a)example.com/new and dovecot is looking in /usr/local/virtual/user(a)example.com/Maildir/new For the local users, /home/user/Maildir is the right directory. for right now I've had to kludge a script that moves mail from /usr/local/virtual/user(a)example.com/new to /usr/local/virtual/user(a)example.com/Maildir/new every two minutes. -- First we must assume a spherical cow.

[Dovecot] Maildirmake equiv?
by LuKreme 19 Aug '13

19 Aug '13

Since I am using dovecot I do not have courier installed, but Courier had a very handy tool for making maildir folders called `maildirmake` which I used in some automated backup scripts. How do I duplicate maildirmake in dovecot? for example: #!/bin/bash # v1.2a Testing for new dovecot install # Archive mail from folders without [0-9]{4} Maildirs # after they are 21 days old to a yearly folder MDIR="$HOME/Maildir" MDM="/usr/local/bin/maildirmake" YEAR=`/usr/local/bin/gdate -d "last month" '+%Y'` echo "The Year is $YEAR..." OIFS=$IFS IFS=" " for I in `find $MDIR -maxdepth 1 -mindepth 1 -type d| egrep -v "[0-9][0-9][0-9][0-9]"`; do MYDIR="${I}" TBASE=`basename $MYDIR` # if [ ! $TBASE == "Maildir" ]; then TDIR=`dirname $MYDIR` TARGET="${TDIR}/.zz${TBASE}.${YEAR}" # echo "$MYDIR $TARGET" if [ -d "$MYDIR/cur" ]; then echo -n "Processing ${MYDIR} => ${TARGET}..." if [ ! -d "${TARGET}" ]; then echo "" echo -n "WARNING ${TARGET} does not exist. invoking $MDM ${TARGET}..." $MDM "${TARGET}" fi if [ -d "${TARGET}" ]; then # echo "$TARGET does exist, moving files" find ${MYDIR}/cur -type f -ctime +21 -exec mv {} ${TARGET}/cur/ \; echo "done." else echo "$TARGET does not exist" fi fi # fi done IFS=$OIFS -- Forever was over. All the sands had fallen. The great race between entropy and energy had been run, and the favourite had been the winner after all. Perhaps he ought to sharpen the blade again? No. Not much point, really.

[Dovecot] dovecot is working, sort of

I have dovecot setup and authenticating away for local users, but when I try to add MySQL users from postfix admin, not only does that fail, but all authentication fails. This configuration does not work: doveconf -n # 2.2.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE i386 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } 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 } and I get the following errors for *ALL* attempts to connect, not just sql ones: mail dovecot: imap-login: Error: Timeout waiting for handshake from auth server. my pid=10591, input bytes=0 Aug 14 22:56:36 mail dovecot: imap-login: Error: Timeout waiting for handshake from auth server. my pid=10592, input bytes=0 mail dovecot: auth: Fatal: mysql: Missing value in connect string: password-dovecot mail dovecot: master: Error: service(auth): command startup failed, throttling for 60 secs mail dovecot: imap-login: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=67.176.106.217, lip=75.148.117.91, TLS, session=<U82VTPXjvQBDsGrZ> This configuration works, but only for local users obviously: # 2.2.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE i386 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passed } The dovecot-sql.conf.ext file is: $ cat /etc/dovecot/dovecot-sql.conf.ext driver = mysql connect = host=localhost dbname=postfix user=dovecot password-dovecot default_pass_scheme = CRYPT password_query = select password from mailbox where username ='%u' user_query = select concat('/usr/local/virtual/', maildir) from mailbox where username = '%u; #iterate_query = SELECT username AS user FROM users Both to the password_query and user_query lines return the right results when I do them manually in MySQL. The one thing I am very unsure of is the default_pass_scheme (the postfixdb is a postfixadmin db), but even if that were completely wrong, it seems like the local users should still be able to authenticate even if the MySQL ones cannot? -- And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does.
