[Dovecot] listen directive changed?
by Nick Edwards 20 Apr '13

20 Apr '13

Timo, Is the global listen directive supposed to be a governing directive, like in apache? or is it there just in case you dont use it in protocols? I set a specific ipv6 address in global listen, but use [::] in proto Testing to a secondary IP, not in the global listen, it still connects, so can I ask has the original use of global listen been deprecated? ciao

[Dovecot] Moving mail servers, moving mailboxes
by Gregory Sloop 19 Apr '13

19 Apr '13

So, I've done some searching - but search terms are hard to come by, that work, for this query. In short, migrating a RHEL 5.9 server running the back-ported Dovecot 1.0.7 To: Ububtu 12.04 with 2.0.19, I believe. [I'm not against compiling a more recent version if there's some real advantage to doing so. But I'd certainly prefer to stay with the packaged version.] Most users are POP3, with some leaving messages on the server for a while. Other users are IMAP - whole mail repository on server. --- In an ideal world, I'd like to simply copy all the mailboxes/dirs from one server to the other. [Local/LAN file copies are possible] It would be great if the message ID's wouldn't change, so the read/unread/new etc status all all the messages wouldn't change between the two servers for POP/IMAP. --- So, does anyone have a reasonable walk-through for doing so? Is this a poor idea? Should I simply set myself on fire now and save everyone a lot of hassle? :) Would you suggest an alternative, and tell me if it might achieve the objectives above? I'm more than glad to take pointers to threads on this topic. I just haven't been able to dredge this up with my Google-foo. TIA -Greg

[Dovecot] Multiple Logins on same accounts from different stations, RE-POSTING
by HL 19 Apr '13

19 Apr '13

Sorry List, I am reposting with dovecot -n ------------------------------------------------------------------ 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 -------------------------------------------------------------------- Thanks

[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 ?

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.
