[Dovecot] access to root mail through Dovecot on VPS
by surabaja＠gmail.com 18 Jul '06

18 Jul '06

Hello, I just installed dovecot and postfix on a Fedora Core VPS. The VPS will not allow me to ssh directly as user "root" i.e.: I must first login as a non-root user and then "su" into root. My question is: is there a way to read my root mail through Dovecot ? How should I setup the Thunderbird account ? Thank you... SJ

[Dovecot] bug in 1.0RC2?
by Renaud Allard 17 Jul '06

17 Jul '06

Hello, I have a small problem with dovecot 1.0RC2. This didn't happen with former versions. There are imap processes that are left open a long while after the client disconnected. I am running dovecot on OpenBSD 3.8. Below is the output of a process list. As you can see, there are many imap processes for the same login running. simon 11593 0.0 0.1 924 1140 ??

[Dovecot] pop3 auth problem solved!
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow techies, OK... This is going to go down as one of those "D'Oh!" moments in the world of computers. Boy, do I feel dumb... In short: I found the problem. One miserable little line in 'dovecot.conf' called 'auth_default_realm =.' I had this set to 'bluefeathertech.com,' thinking it was necessary to do so. I was wrong, at least for my environment, and the stupid clues were right in front of me in the logfile all the time! For the benefit of others who may run into this: Setting a domain name in this entry causes that domain name to be automatically appended to usernames when they log in. No wonder nothing ever matched in /etc/passwd! My deepest thanks to Frank Cusack for giving me the idea. Something he said in his post, in response to my initial one, got me thinking about things getting appended to the user name, and the rest is history. pop3 and pop3s both work just fine now, thanks. ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] pop3 authentication problems: Still got 'em...
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow users, This is just a heads-up to let the list know that I'm still unable to get ANY sort of pop3 or pop3s authentication to work with Dovecot. Just as a sanity check, I set up an entirely separate system, running FreeBSD 6.1 production, postfix 2.3, and Dovecot 1.0rc2, as a testbed. I got the exact same problem that I had with the NetBSD 3.0 production server, specifically that Dovecot refuses to authenticate a user with either basic pop3 or pop3s. The way I see it, I may as well try to get basic pop3 working first. If it doesn't, pop3s will never work. This first quote is taken from the mail client (Pegasus) trying to establish a regular, unencrypted pop3 session. -=-=-=-=-=-=- [*] Connection established to 192.168.42.80 >> 0058 +OK AVG POP3 Proxy Server 7.1.368/7.1.394 [268.10.1/389] << 0013 USER kyrrin >> 0005 +OK << 0016 PASS XXXXXXXXX >> 0029 -ERR Authentication failed. -=-=-=-=-=-=-=- As you can see, the user ID of 'kyrrin' is getting passed as just that, and Dovecot at least seems to recognize it. I say this as a prefix to the next log clip, which will be the corresponding entry from /var/log/maillog, in which the user name is being presented (for whatever reason) in FQDN format. Note that pam was added just as an experiment. It failed too, despite the presence of a 'dovecot' file, containing the following, in /etc/pam.d -=-=-=-=-=-=-=- pioneer# cat /etc/pam.d/dovecot auth required pam_unix.so nullok account required pam_unix.so pioneer# -=-==-=-=-=-=- This would be the /var/log/maillog entry corresponding to the above-referenced Pegasus session. -=-=-=-=-=-=-=- Jul 16 11:24:38 pioneer dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.42.80rip=192.168.42.40 resp=AGt5cnJpbgBocDIxZHZlbTc= Jul 16 11:24:38 pioneer dovecot: auth(default): pam(kyrrin(a)bluefeathertech.com,192.168.42.40): pam_authenticate() failed: authentication error Jul 16 11:24:38 pioneer dovecot: auth(default): cache(kyrrin(a)bluefeathertech.com,192.168.42.40): User unknown Jul 16 11:24:40 pioneer dovecot: auth(default): client out: FAIL 1 user=kyrrin(a)bluefeathertech.com Jul 16 11:24:49 pioneer dovecot: pop3-login: Aborted login: user=<kyrrin(a)bluefeathertech.com>, method=PLAIN, rip=192.168.42.40, lip=192.168.42.80 -=-=-=-=-=-=-=- This next bit is the auth default section of my dovecot.conf file.

[Dovecot] auth with kerberos
by Renaud Allard 16 Jul '06

16 Jul '06

Hello, I am running dovecot 1.0RC2 and I'd like to know if there is a way to make dovecot provide PLAIN, LOGIN, CRAM-MD5, NTLM authentications from a kerberos database. GSSAPI works great, but I currently have to have two password databases, one for GSSAPI and one for all the others. What I'd like is to have only one password database (namely kerberos). I know that cyrus-sasl (which most of you don't like I think ;)) can provide such authentications, but I haven't found the way to configure dovecot to do the same. Any input welcome.

Re: [Dovecot] Deliever in RC2 incorretly outputs "saved mail to INBOX"
by Alex Pimperton 14 Jul '06

14 Jul '06

Hi All, I've recently upgraded to RC2 (debian package) and now I get the following message in syslog all the time: Jul 14 15:51:04 server01 deliver(alex): saved mail to INBOX This seems to happen for every mail, despite some being filtered into different folders. It goes like this: Mail arrives from Ubuntu mailing list: Jul 14 15:53:49 server01 postfix/qmgr[19023]: D51A95C023: from=<ubuntu-users-bounces(a)lists.ubuntu.com>, size=4319, nrcpt=1 (queue active) I get this message: Jul 14 15:53:51 server01 deliver(alex): saved mail to INBOX Postfix sends to deliver: Jul 14 15:53:51 server01 postfix/local[29843]: D51A95C023: to=<alex(a)placet.co.uk>, relay=local, delay=29, status=sent (delivered to command: /usr/lib/dovecot/deliver) ...and a few seconds later it shows up in my Ubuntu-Users folder, exactly where my sieve rule sends it. Is this a bug? Alex -- This message has been scanned for viruses and dangerous content by the MailScanner at Placet.co.uk, and is believed to be clean.

[Dovecot] Backing up mail
by Davide Bolcioni 14 Jul '06

14 Jul '06

Greetings, in backing up mail stored according to default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u is it safe *not* to backup the .imap subdirectory ? I am currently using dovecot-0.99.13-3.FC3. When restoring, I guess the safe option would be to zap the contents of .imap so that it gets rebuilt, correct ? Thank you for your consideration, Davide Bolcioni -- Paranoia is a survival asset.

[Dovecot] TLS Issues - Plain Text login?
by Timothy White 14 Jul '06

14 Jul '06

I'm trying to setup IMAP, so that it works via secure connections. I have it working fine over SSL, now I wish to get TLS to work. I have set imap and imaps to both listen on *, and have disable_plaintext_auth = yes, which according to the docs, Disable LOGIN command and all other plaintext authentications unless SSL/TLS is used (LOGINDISABLED capability). So the problem is now, that TLS doesn't work. Trying it with thunderbird, I get a message about login being disabled, and to check my settings and such. The port is correct (imap, not imaps), and I have it to always use TLS. I see the following in my logs Jul 14 16:35:46 mafeking dovecot: imap-login: Aborted login: rip=58.7.136.163, lip=203.30.47.34, TLS Any ideas? To me it appears to be using TLS, so why doesn't thunderbird work? Is it the LOGINDISABLED capa keyword? Is it dovecot telling Thunderbird the wrong capa when using TLS? It all works fine with SSL, and the port (in thunderbird) set to the imaps port. The logs show lines like below when using SSL. Jul 14 16:36:32 mafeking dovecot: imap-login: Login: user=<joeblogs>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any ideas? Or should I just force SSL?

[Dovecot] How to create rules?
by Romeo Theriault 14 Jul '06

14 Jul '06

Hi, I have dovecot installed and working fine. I would like (server side) a rule runs on all messages and if it finds certain words in the message it will run a script which will send a new email. How can I create these rules? Do I need another piece of software? Thank you, Romeo
