[Dovecot] Overriding IMAP commands
by Tony Tsang 04 Jun '07

04 Jun '07

Hi all, I am writing a plugin to override some built-in imap commands. But when client logs out, imap segfaults during unregistering commands. What is the correct procedure for overriding imap commands in dovecot? Thanks. Tony Tsang.

[Dovecot] What are they trying to do here?
by Jon Slater 04 Jun '07

04 Jun '07

Hi! I’m new to the list, and I’m not really having a ‘problem’, but I’m seeing something in my log files that I wonder if I should be concerned. I’ve been using Dovecot (dovecot-0.99.14-8.fc4) on my Fedora Core 4 (kernel 2.6.17-1.2142_FC4) machine from quite some time. For the last few days, I’ve been seeing this in my daily ‘Logwatch’ e-mail: dovecot: Authentication Failures: rhost= : 139 Time(s) root: 13 Time(s) Unknown Entries: check pass; user unknown: 139 Time(s) So it looks pretty obvious that someone (using root and an assortment of other login names) is trying to access by dovecot server. My first ‘issue’ is I can’t find a log file anywhere that tells me the IP address of the attacker. I see a series of ‘authentication failure’ messages in my /log/messages file: May 29 21:23:35 mydomainname dovecot(pam_unix)[15317]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=root May 29 21:23:35 mydomainname dovecot(pam_unix)[15318]: check pass; user unknown May 29 21:23:35 mydomainname dovecot(pam_unix)[15318]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= May 29 21:23:36 mydomainname dovecot(pam_unix)[15320]: check pass; user unknown May 29 21:23:36 mydomainname dovecot(pam_unix)[15320]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= But I don’t find anything in any other log files to indicate where this is coming from. Secondly, I’m wondering if I have anything to be concerned about. Thanks in advance for you help! Jon No virus found in this outgoing message. Checked by AVG Free Edition.

[Dovecot] dovecot scaling issue?
by it-dovecot＠ml.epigenomics.com 04 Jun '07

04 Jun '07

Hi! We are running dovecot-imapd on Debian sarge out of the backports.org packages (version 1.0.rc15-1~bpo1). We have ~ 80 clients using secure IMAP. I understand that imap-login has to run for every SSL connection. Thus I already increased the max value for the number of imap-login processes. But unfortunately dovecot is unresponsive from time to time. Where can I tune the installation? Do I need to upgrade to 1.0.0, for which no backported packages exist for Debian sarge? This is the output of dovecot -n: log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/courier/imapd.pem ssl_key_file: /etc/courier/imapd.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/.Maildir:INDEX=/var/cache/dovecot/INBOX.%u:CONTROL=/var/cache/dovecot/INBOX.%u mail_full_filesystem_access: yes maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: public separator: . prefix: shared. location: maildir:~/.Maildir/shared:INDEX=/var/cache/dovecot/shared.%u:CONTROL=/var/cache/dovecot/shared.%u auth default: verbose: yes passdb: driver: passwd userdb: driver: passwd Homedirectories are on NFS, /var/cache/dovecot is a local filesystem. Clients are mostly Thunderbird, where max connection to IMAP server is set to 5.

[Dovecot] TLS errors when vodafone connecting to dovecot server.
by Andrew Pounce 04 Jun '07

04 Jun '07

Hi, I've been trying to setup the vodafone email sync ( provided by visto apparently ) and have not been able to do so - I'm getting an error message in my mail logs which looks as if there is a problem with certificates somewhere. May 31 16:49:39 imap dovecot: imap-login: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown [206.124.112.22] Thunderbird has no problems with using TLS against this server and I'm not entirely sure if dovecot (or openssl ) is generating the message or if it is something being passed from the remote end. I've had a look around but not found anything on the web pages. Thanks, -Andrew -- Andrew Pounce - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Don't look now, but the man in the moon is laughing at you.

[Dovecot] CMU Sieve pluigin missing proper charset support
by Jan Srzednicki 04 Jun '07

04 Jun '07

Hello, After testing the Sieve plugin for the LDA, I have noticed that it does not handle charset issues properly. IETF draft says: 4.3. Subject and From Parameters The ":subject" parameter specifies a subject line to attach to any vacation response that is generated. UTF-8 characters can be used in the string argument; implementations MUST convert the string to [RFC2047] encoded words if and only if non-ASCII characters are present. Implementations MUST generate an appropriate default subject line as specified below if no :subject parameter is specified. (see http://tools.ietf.org/html/draft-ietf-sieve-vacation-07) The problem is that the dovecot plugin does not convert the string to RFC2047 encoded words, it treats it literally and thus sends malformed (from RFC's point of view) message - with improper Subject field encoding. Any chances of getting that fixed? greetings, -- Jan Srzednicki w(a)expro.pl

[Dovecot] SSHA salt?
by Andreas Baitis 01 Jun '07

Hi there, I was wondering if someone could explain how dovecot/dovecotpw produces salt for use in ssha passwords, I'd like to replicate this in PHP so I can write my passwords from php in ssha instead of just sha1. Thanks in advance, Andrea Baitis
