[Dovecot] Dovecot and port forwarding
by Slawomir Wawak 19 Apr '13

19 Apr '13

Hello! I try to configure POP3s with Dovecot. My mail server is behind router and I forward 995 port from router to mail server. POP3s works ok when I log directly to 995 on server. Unfortunately, it shows nothing when I log from outside. It happens also when the firewall is off. All I can see in log is this: Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2002, ret=-1: unknown state [123.123.123.123] Apr 19 13:39:43 hostname dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 19 13:39:43 hostname dovecot: auth: Debug: auth client connected (pid=17056) Apr 19 13:39:47 hostname dovecot: pop3-login: Disconnected (no auth attempts): rip=123.123.123.123, lip=10.0.0.2, TLS handshaking: Disconnected (hostname and IPs changed) My config: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-40-generic-pae i686 Ubuntu 12.04.2 LTS auth_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3s { address = * } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_ssl = yes I think it might be something related to SSL, but what?

You can sort of get that from the logs. For example, from my logs Apr 18 23:08:19 server dovecot: imap(user): Disconnected: Logged out in=9516 out=89038 telling you how many bytes tranferred in and out during the session. > Is there any utility which does this sort of full monitoring? > I tried doveadm who to get the details of logged in users. > but its not returning any output even though i am logged in to the server. "doveadm who" ought to work. What does it return? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] ot: moving files/dirs from terminal ?
by voytek＠sbt.net.au 19 Apr '13

warning, dumb question ahead: I want to re-arrange, rename & create some sub directories below INBOX in my own mailbox; if I use 'mc' from terminal to do so, can that cause me grief...? do I need to ?? re-index explicitly?? afterwards ? how to re-index ? or is that a really _B_ad idea, and, I should do it through say squirrelmail client ? thanks for any pointers! # dovecot --version 2.1.1 INBOX mail path /var/spool/mail/vhosts/dom.tld/voytek(a)dom.tld

[Dovecot] Slooow imap copy to "Sent" folders
by Frank Bonnet 19 Apr '13

19 Apr '13

Hello Many users here use the "copy to Sent folder" using the IMAP protocol with Dovecot 2.1.15 on a FresBSD 9 server. Since few days this operation ( copy to sent folder ) became longer than before , it could takes several seconds to complete even the message is very short. Is there a parameter I could tweak to boost this a bit ? may users complain with reason thank you

Dear Sir, I want to get some statistics of dovecot IMAP server like the number of current IMAP connections, who is logged in to the Dovecot server, bandwidth usage. Is there any utility which does this sort of full monitoring? I tried doveadm who to get the details of logged in users. but its not returning any output even though i am logged in to the server. Thanks and regards, Suja -- View this message in context: http://dovecot.2317879.n4.nabble.com/IMAP-monitoring-tp41723.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Problem with "convert" Plugin
by Andreas Schnederle-Wagner - Futureweb.at 18 Apr '13

18 Apr '13

Hello, I got a Problem with the "convert" Plugin. Trying to convert from mbox to maildir Format. OS: CentOS release 5.8 (Final) dovecot -version: 1.0.7 (Centos RPM) convert Plugin call: convert_mail = mbox:/opt/pop3/%u:INBOX=/var/spool/mail/%u When converting to maildir - POP3 works fine (except the lost UIDL - so every server-saved message is double downloaded - but did not find any fix for this problem with convert plugin) But the IMAP In-Boxes give me some headache . All Folders are converted correct - and displayed in Mail Client. But all Mails in the IMAP INBOX are "lost" (at least Mail Client won't show them anymore) Newly delivered Mails to the Inbox work - but all older ones are missing. When looking into this Folder: /var/maildata/USER/Maildir/cur/ I can see that newly delivered mails look like this: 1366122898.14776_0.SERVERNAME:2, And the old - converted ones like this: 1366119758.P14442Q12M682874.SERVERNAME:2, Can someone point me in the right direction why the converted Mails are missing? (It worked on other Servers - about 1 year ago - without any problem?!)

[Dovecot] qmail-ldap LDA Delivery and sieve
by Ruda Porto Filgueiras 18 Apr '13

18 Apr '13

Hi, I'm using dovecot 2.1.7 on debian Squeeze with ldap integration. Almost everything is working fine and I would link to thank all developers for this amazing piece of software. But after changing my qmail-ldap to do LDA integration get all the benefits from LDA and sieve, some emails return with failure like this: <sar(a)mondialline.com.br>: lda(sar): Fatal: Unknown argument: sar Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] It happens on messanges that could not be delivered and need to be returned to the sender. I'm using the configuration described on wiki to do qmail-ldap integration: http://wiki.dovecot.org/HowTo/qmailldap The relevant delivery command is: | /usr/lib/dovecot/dovecot-lda -a $RECIPIENT -f $SENDER -d $USER I also tried to use this way, as documented here: http://wiki2.dovecot.org/LDA/Qmail | /var/qmail/bin/preline -f /usr/lib/dovecot/dovecot-lda But in that case, some sieve plugins can't detect the mail recipient, like vacation plugin. Finally, the vacation plugin also is not doing email forwarding when I use the first delivery option above.

[Dovecot] Multiple Logins on same accounts from different stations
by HL 18 Apr '13

18 Apr '13

Hi, all I've recently upgraded to 2.1.16 and found my self in deep .... There are 4 accounts in my setup that need to be accessed simultaneously by 5-6 PCs on a local lan. The thing is if a user A updates, deletes, flags mail messages in the imap folders the changes don't get propagated to the other mail clients. To state this clearly, PC (A) thunderbird has an account SALES, Maildir etc PC (B) thunderbird also has the SALES account. Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't. This never occured with previous version 1.2.xx I am attaching my doveconf -a output .. Please Help, Thanks in advance Harry
