[Dovecot] separating logs by port
by Hanno Böck 25 Apr '14

25 Apr '14

Hi, I wanted to ask if there's an easy way to log the port in dovecot. The background is that, as everyone's probably aware, pop3/imap usually listen on two ports (110/995 for pop3, 143/993 for imap). One port is the "classic" port that allows unencrypted and STARTTLS connections, the other is the legacy SSL port that allows TLS only connections. The legacy SSL ports are considered deprecated and I'd like to know if I can deprecate them on my severs. Therefore I'd like to know how many users use them, but at the moment I can't see which port my users use. I haven't found an easy way to detect that. The easiest thing would be if there'd be a way to add the port number to the pop3-login/imap-login lines in the log files. Any way to do that? cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

[Dovecot] Multiple Instances Of Dovecot On One Messagebase
by Christian Felsing 25 Apr '14

25 Apr '14

Hello, I would like to run multiple instances of Dovecot with same message base (maildir format) Will this set up work or would that destroy message base? Intention is to offer different authentication methods to users, username/password and client certificates. Those instances should run on different IP addresses which is supported by Dovecot. Unfortunately Dovecot does not allow different auth configs in "local <ip> {}" sections. best regards Christian

Re: [Dovecot] integration of old mails into new dovecot Maildir

Steffen, Thank you for all your help in helping me resolve my mail integration. I was able to get the old mails integrated into the new server following your suggestion of 1:1 transfer. Thanks again and have a good day. -----Original Message----- From: Steffen Kaiser [mailto:skdovecot@smail.inf.fh-brs.de] Sent: Monday, April 14, 2014 2:18 AM To: K. C.

My old mail server used 2.x dovecot version. you post very little information: 1) how are the messages storred on the old server, which storage backend do you use, maybe Maildir? 2) the storage backend on the new server? 3) do you care about the message UIDs? 4) How many users do you have (approx.) and can you access the user's mailboxes via IMAP, e.g. using a master user or do you know their password or can you switch to a known password during migration of one particular user? 5) Did you've changed namespaces? - From your first post I figure that the basic mail server functionality of the new server is working, most importantly login, message delivery and retrieval. > -----Original Message----- From: Steffen Kaiser > Sent: Thursday, April 10, 2014 6:14 AM > To: K.

[Dovecot] Regarding Quota
by Joy 24 Apr '14

24 Apr '14

Dear All, One of my user is using sieve to make a copy of incoming mail in another folder all is working file. I have seen that he is using 15GB out of 20GB space of his mailbox, while calculating the same using du command returns only 9.5 GB. I am not facing this issue with any of other user. Is there something going wrong or misconfiguration causing this.

[Dovecot] Help implementing username_format in auth PAM driver
by lee＠trager.us 24 Apr '14

24 Apr '14

While configuring my server with dovecot I noticed that the PAM authentication driver does not support the username_format option as does the password file driver. This didn't seem too hard to implement so I through together a patch. As you can see in the attached patch I only modify the username sent to PAM. Despit doing this I run into the domain lost issue(http://wiki2.dovecot.org/DomainLost). This prevents me from using the domain name in my mail_location config string. What I don't understand is why does changing the username string sent to PAM for authentication trigger this issue? Shouldn't dovecot continue to use the client supplied username as I am *not* changing it anywhere in my config? Thanks, Lee

You know best whether you want to take the risk of compromising passwords on your system (including compromised accounts using for spamming and blowing your mail reputation to smithereens), but I don't know whether your customers do. They may think they are only risking their Email, but it can be leveraged to also gain access to other authentication systems e.g. "Forgot password" feature. You can suggest the installation of a SSL proxy for those holdouts that won't switch mail readers (stunnel even has support down to Win98). https://www.stunnel.org/ports.html These days, cleartext passwords over the network is just begging to be compromised.

Re: [Dovecot] ImapTest utility not compiling
by Hein, Brad 23 Apr '14

23 Apr '14

* Found my error. I moved the dovecot source code after compiling it. Didn’t realize there were embedded/absolute URLS within the dovecot source tree. All I needed to do was make clean && make dovecot, then imaptest compiled no problem. [Brad Hein] From: <Hein>, Local Administrator <Brad_Hein(a)cable.comcast.com<mailto:Brad_Hein@cable.comcast.com>> Date: Wednesday, April 23, 2014 at 2:00 PM To: "dovecot(a)dovecot.org<mailto:dovecot@dovecot.org>" <dovecot(a)dovecot.org<mailto:dovecot@dovecot.org>> Subject: ImapTest utility not compiling Following the wiki instructions here: http://www.imapwiki.org/ImapTest/Installation I’ve run into a wall trying to compile the imapTest utility (dovecot compiled without any problems). I think there’s a problem in the imapTest utility? Copy/pasted compile output and attached. The gist of the problem seems to be that imaptest can’t find the dovecot headers and libraries (configure script was executed like this: ./configure --with-dovecot=/usr/src/dovecot-20140420 checkpoint.c:3:17: error: lib.h: No such file or directory checkpoint.c:4:17: error: str.h: No such file or directory <and many more> Based on these errors I believe there’s a compatibility problem between the current imapTest utility and dovecot. The configure script said to report errors to this email address. [Brad Hein]
