On an Ubuntu Server 12.04 system with Dovecot 2.0.19 I am having some trouble with the Dovecot passwords. I am finding this in the logs when I unsuccessfully try to log in: Jul 07 08:13:25 auth-worker: Debug: pam(user(a)someDomain.com,212. 179.241.14): lookup service=dovecot Jul 07 08:13:25 auth-worker: Debug: pam(user(a)someDomain.com,212.179.241.14): #1/1 style=1 msg=Password: Jul 07 08:13:27 auth-worker: Info: pam(user(a)someDomain.com,212.179.241.14): pam_authenticate() failed: Authentication failure (password mismatch?)

[Dovecot] CaCert certificate configuration help needed
by gw1500se 04 Jul '13

04 Jul '13

I was not able to find specific help for configuring the crt file for CaCert. I gleaned from examples the following order: server certificate CaCert class 3 certificate Cacert root certificate However, when I try to configure my mail reading for IMAP, Dovecot shows the following error in the log: dovecot: imap-login: Aborted login (no auth attempts): I am assuming, based on searches for this error, that my crt file is not correct but I don't know what to do at this point. Can someone steer me in the right direction?

[Dovecot] namespace delivery question
by Laszlo Kiraly 04 Jul '13

04 Jul '13

Hi list, I like to have public mailboxes in addition to other private in the same domain, and manage the public mailbox permissions through acls. For example: info(a)domain.com <- public, readable by user2 user1(a)domain.com <- private user2(a)domain.com <- private The mailboxes are virtual, authentication through pam (kerberos). The public mailbox doesn't have valid kerberos account. My smtp server is exim 4.80. I set the mail delivery to lmtp. I couldn't find solution in the documentation, how can I manage the email delivery to the public namespace? There is a -m option in the lda delivery where you can give namespace prefix. Maybe it's good for this, but I couldn't find any information how can I do this with lmtp? my dovecot config: test:~# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.0.0-1-686-pae i686 Debian squeeze/sid managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { location = sdbox:/home/vmail/public/%u prefix = public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = sdbox:/home/vmail/private/%n mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . } passdb { driver = pam } plugin { acl = vfile sieve = /home/vmail/%n/.dovecot.sieve sieve_dir = /home/vmail/%n sieve_global_dir = /home/vmail/sieve } protocols = " imap lmtp sieve" service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=1035 gid=8 home=/home/vmail/%Lu allow_all_users=yes driver = static } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } Best regards: László Király

[Dovecot] dnsbl feature for dovecot
by John Fawcett 04 Jul '13

04 Jul '13

dnsbl's are a popular method to prevent listed ips from making connections to mta software. cf. postscreen_dnsbl_sites in postfix Would it be possible to introduce such a feature in dovecot, so that connections can be denied based on a dnsbl lookup (where the precise dnsbls used are configurable)?

I'm using dict quota like so: quota = dict:User quota::file:/[path]/quotas/%u [path]/quotas/ is a tmpfs. The idea is to do less work on disk. Other than forcing dovecot to rebuild quotas on a reboot, are there any downsides? Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net
