[Dovecot] Dovecot fails to deliver big messages
by disconnect 10 Jul '09

10 Jul '09

Description of problem: Hello, I am having problems with Dovecot not delivering 'big' emails. Small email with 1-2 kb text delivered fine. If the message about 200kb long or more it freezes. I am also getting "copy: i_stream_read() failed: Permission denied" erros in Dovecot log files. I have tried switching off selinux and settings 777 permissions to my mail_location - it both dont help. Here is my cfg info: # 1.2.0: /etc/dovecot.conf # OS: Linux 2.6.29.5-191.fc11.x86_64 x86_64 Fedora release 11 (Leonidas) ext4 protocols: imap pop3 listen: * ssl: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: PREVED MEDVED first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 12 last_valid_gid: 12 mail_location: maildir:/home/email/%d/%n mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: mail group: mail Version-Release number of selected component (if applicable): I'm running FC11 with exim and dovecot installed.

[Dovecot] non-lowercase usernames
by Timo Sirainen 10 Jul '09

10 Jul '09

Should I just make Dovecot lowercase usernames by default in v2.0? auth_username_format = %Lu Does anyone actually want to use non-lowercase usernames?

[Dovecot] Sieve on full mailbox
by ian＠comtek.co.uk 10 Jul '09

10 Jul '09

Hi, We are using dovecot with "mail_plugins = cmusieve". I have Avelsieve in SquirrelMail for users to interact with it. Is there any way I can allow users to run their sieve script on an entire mailbox? While the normal case of having messages filtered as they are delivered to the Maildir makes sense it would be useful for a few users to be able to apply their rules to every message on a one-off basis. If there is a binary which will do this job? I could adapt the SquirrelMail interface to invoke it with appropriate arguments. Thanks, Ian

[Dovecot] Dovecot delivering mail in the wrong directory location
by Tjerk Wolterink 10 Jul '09

10 Jul '09

Hello everybody,my new server is setup with postfix as a MTA and dovecot as a MDA, mysql is used as a user db, and postfixadmin is used to setup accounts. Login via pop works fine, also sending via smtp works fine. HOWEVER: when i sent a mail by hand via smtp it is delivered in the wrong directory. For example for test(a)xdatasystem.com i have the following directory: /home/vmail/xdatasystem.com/test However the mail is delivered to this directory: /home/vmail/test(a)xdatasystem.com/ I cannot figure this out as dovecot is correctly configured. ( think) Here is the important part of my dovecot.conf (sorry for the indents): === DOVECOT.CONF === *disable_plaintext_auth = no* *log_timestamp = "%Y-%m-%d %H:%M:%S "* *mail_location = maildir:/home/vmail/%d/%n/Maildir* *mail_access_groups = vmail* *first_valid_uid = 100* *first_valid_gid = 100* * * *protocol imap {* *}* * * *protocol pop3 {* *pop3_uidl_format = %08Xu%08Xv* *}* *auth default {* *mechanisms = digest-md5 plain* *passdb sql {* *args = /etc/dovecot/dovecot-sql.conf* *}* *#userdb sql {* *#args = /etc/dovecot/dovecot-sql.conf* *#}* * * *userdb static {* *args = uid=vmail gid=vmail home=/home/vmail/%d/%n* * }* * * *user = root* *}* === DOVECOT.CONF === Has anybody a clue?

[Dovecot] Optimal quota method for SQL
by Tom Sommer 10 Jul '09

10 Jul '09

Hi, I just installed 1.2.0 and I'm gonna set up some quota on my vitual users. I' ve got dovecot set up as LDA, and currently I'm using the dict-mysql method described for 1.2.0, but it's not really working at all. Am I correct in assuming that with this method I can define the quota limit in my dict (sql field)? This is my current config: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { quota = dict:user::proxy::quotadict quota_rule = *:storage=0:messages=0 } protocol lda { mail_plugins = quota ..... } I want quota to be disabled unless otherwise specified in my SQL database. // Tom

[Dovecot] Managesieve fails to retrieve scripts > 8kB on Dovecot 1.1.16
by John Marshall 10 Jul '09

10 Jul '09

After some help with debugging tips on #dovecot, I have established that a sieve script on Dovecot 1.1.16 has to be less than 8kB in order to be retrieved by a managesieve client. I have been using managesieve for about 6 months over as many 1.1.n versions of dovecot as have been around during that time and hit this problem when I upgraded to Dovecot 1.1.16. I have gone back to Dovecot 1.1.15 and can once again manage my 9kB sieve script remotely. Symptoms were that managesieve login was OK but instead of displaying my sieve script, the script editing window was empty. After 30 seconds the client gave me a timeout message. If I entered a small script in the empty client edit window and saved it, the new, small script was saved to the server and became active. I could then successfully retrieve and edit that small script. I tried hacking a few lines at a time out of my 9kB script (locally on the server). When it was down to 8.4KB I still couldn't get it through managesieve. The next hack took it down to 7.7kB and I could get that through managesieve. So, I'm guessing there's a magic 8192 number in there somewhere - perhaps a buffer? Server dovecot 1.1.16 dovecot-sieve 1.1.6 dovecot-managesieve 0.10.6 FreeBSD 7.2 Client Thunderbird 2.0.21 Sieve 0.1.6 A special thanks to all who write this stuff: it's great! -- John Marshall

[Dovecot] First V1.2 compile questions
by Stewart Dean 09 Jul '09

09 Jul '09

1) I see that the --without-pop3d option has gone away. What does this imply, i.e why was that done? Is there some other way that you now avoid compiling the POP code? Are there any other discontinued options? 2) There was some talk a while back about changing how and where the plugins were to be built and their code located. Was this implemented? If so, is there any doc on it? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Long delay checking mail with POP w/plain auth
by david hardy 09 Jul '09

09 Jul '09

I just switched from UW-IMAP to dovecot, and it all went smooth, except now I get a 4-5 second delay after connecting to the POP3 server (IMAP is fine). If I switch to auth "mechanisms=login", it is instantaneous - the delay is gone. In my logs I am getting : Jul 9 12:21:03 haleakala dovecot: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=205.168.236. rip=205.168.236. lport=110 rport=62500 resp=<hidden> Jul 9 12:21:03 haleakala dovecot: auth(default): plain(?,205.168.236.): invalid input Jul 9 12:21:03 haleakala dovecot: auth(default): new auth connection: pid=2750 Jul 9 12:21:03 haleakala dovecot: auth(default): client out: FAIL 1 and then it tries again apparently, and succeeds: Jul 9 12:21:08 haleakala dovecot: auth(default): client in: AUTH 2 PLAIN service=pop3 lip=205.168.236. rip=205.168.236. lport=110 rport=62500 resp=<hidden> Jul 9 12:21:08 haleakala dovecot: auth-worker(default): pam(divad,205.168.236.): lookup service=dovecot Jul 9 12:21:08 haleakala dovecot: auth-worker(default): pam(divad,205.168.236.): #1/1 style=1 msg=Password: Jul 9 12:21:08 haleakala dovecot: auth(default): client out: OK 2 user=divad Jul 9 12:21:08 haleakala dovecot: auth(default): master in: REQUEST 217 2552 2 Jul 9 12:21:08 haleakala dovecot: auth(default): passwd(divad,205.168.236.): lookup Jul 9 12:21:08 haleakala dovecot: auth(default): master out: USER 217 divad system_groups_user=divad uid= gid= home=/home/david Jul 9 12:21:08 haleakala dovecot: pop3-login: Login: user=<divad>, method=PLAIN, rip=205.168.236., lip=205.168.236.
