[Dovecot] SSL with startssl.com certificates
by Dan Langille 10 Oct '13

10 Oct '13

I'm using Dovecot 2.2.5. I'm setting up and new IMAPS server for personal use (i.e. only me). I have success with self-signed certificates but not with others (e.g. StartSSL.com) With StartSSL certs: I've been able to connect and test commands via: openssl s_client -connect imaps.unixathome.org:993 Can you configure your iPhone or Macbook to access the above? Authentication isn't the issue. Connection is the issue. I've been able to get Thunderbird to connect and access my mail. However, I've been unable to get my iPhone or my Mac configured to use the same IMAP server. On the iPhone, adding the new Mail account causes the Settings app to crash on a persistently consistent basis when adding the new account. The crash occurs when connecting to the IMAPS server. Configuration never completes. I suspect the problem is SSL because in both cases (iPhone and Mac), I see these messages I see in the logs: *** /var/log/debug.log *** Sep 13 11:50:32 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: auth: Debug: auth client connected (pid=31647) Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv2/v3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] *** /var/log/maillog *** Sep 13 11:50:46 imaps dovecot: imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:46 imaps dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=166.137.84.11, lip=199.233.228.197, TLS handshaking: Disconnected, session=<a7AJd0LmWwCmiVQL> /usr/local/etc/ssl/imaps.unixathome.org.crt contains only the cert issued by StartSSL /usr/local/etc/ssl/imaps.unixathome.org.nopassword.key contains a no-password key generated by myself.

[Dovecot] Yet another going from 1.2 to 2.X question: authentication
by Mauricio Tavares 07 Oct '13

07 Oct '13

So in 1.2.9 I had something like this: [...] socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtual # User running Dovecot LDA's deliver } } # Dovecot as SASL Auth socket listen { client { path = /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } } I see I can, per http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL, setup the sasl entry as # Dovecot as SASL Auth service auth { unix_listener /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } what about the lda? From http://wiki2.dovecot.org/LDA I take it would be as simple as service auth { unix_listener auth-userdb { mode = 0600 user = virtual # User running Dovecot LDA's deliver } } Am I correct?

[Dovecot] Panic: file mail-storage.c: line 834 (mailbox_verify_name): assertion failed
by Kamil Andrusz 30 Sep '13

Hello List! I've encountered an error after upgrading my system and dovecot. I guess it's probably a result of a configuration problem, however after quite some tinkering with configuration I am still missing the source of the problem.

[Dovecot] New install not working.
by Rhorer, Leslie 30 Sep '13

30 Sep '13

Hello. I need some help. I was running uw-imap on my IMAP server (so I am using mbox email files), but I was having trouble with Outlook 2013, so I decided to move to dovecot. At first things were looking much better, except that most of my folders, other than the Inbox, were not showing up. I started changing both the dovecot configuration and the folder structure of my mail files, but now I can't even get the Inbox to populate. Outlooks says it is there, along with any folders I create new in Outlook, plus the Trash folder, which is the only non-local folder with anything in it. Try what I might, I can't get my Inbox to populate or any of the existing folders to show up at all. Here is the current output from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 xfs mail_location = mbox:/RAID/home/%u/mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } I have the mail files on a RAID array (separate from the boot arrays) at /RAID/home/<User>/mail.

[Dovecot] Using MailDir but local messages still save in mbox format
by Mike Edwards 30 Sep '13

30 Sep '13

I am using MailDir format for all my virtual users and it is working well. However, if email comes in to a unix system user, it delivers in Mbox format. This is mostly cron jobs that do this. Mail addressed to my virtual users goes to the MailDir locations just fine. None of these mailboxes have ever been created, they are just incorrect assumed addresses. There should NEVER be any email to username(a)my.host.name because everything is virtual. Does anyone know how to fix this? Here is my config. # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.18.1.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_debug = yes auth_mechanisms = plain login cram-md5 ntlm auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_privileged_group = mail 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 mbox_write_locks = fcntl passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Drafts autocreate4 = Sent autocreate5 = Archives autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Drafts autosubscribe4 = Sent autosubscrube5 = Archives sieve = ~/.dovecot.sieve sieve_before = /home/vmail/movespam.sieve sieve_dir = ~/sieve } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } } ssl_ca = /etc/pki/dovecot/ca/dovecot.pem ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_cipher_list = HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3 userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /home/vmail/dovecot-deliver.log mail_plugins = " sieve sieve" postmaster_address = postmaster(a)zeus.deltatechnicalservices.com } protocol lmtp { mail_plugins = " sieve" } protocol imap { mail_plugins = autocreate } protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

[Dovecot] pop3-login problem
by Oleksii Krykun 30 Sep '13

30 Sep '13

Hi! I have dovecot-2.2.5 installed as part of postfix+dovecot+mysql+amavisd. My server has two NICs (Internet and local). /etc/resolv.conf point to ISP DNS. Local names are not resolved. If ISP link goes to down state I see (after about 1minute) a following error: Sep 26 15:44:29 pop3-login: Error: master(pop3): Auth request timed out (received 0/12 bytes) and following informational message: Sep 26 15:44:29 pop3-login: Info: Internal login failure (pid=12809 id=17815) (internal failure, 1 successful auths): user=<xxx(a)xxx.xxx> ..... If link is restored (even for a short time) all works fine again. After next down errors are repeated. I suppose that this is dns issue. Am I wrong? And I have a following question. Is it possible to disable dns requests? I haven't external clients. Or I must fix a name resolution e.g. to use a caching dns server? Thanks.

[Dovecot] proxy: can I use the password returned from passdb to log in to the back-end?
by Justin McAleer 30 Sep '13

30 Sep '13

I am hoping to support encrypted passwords, which I know is generally not allowed in a proxy setup. However, I can return the password in clear-text out of the password database, so I was hoping for something similar to the destuser field. I have successfully used the master password functionality to support encrypted passwords (users impersonating themselves), as long as the back-end server supports that. However, I need to proxy POP3 to Gmail, which does not.

[Dovecot] How to authenticate against SQL DB with custom-ciphered passwords?
by Nicolay Vizovitin 29 Sep '13

29 Sep '13

Hello, I'm about to start developing authentication/password-scheme module for Dovecot. So I would like to get some advice before actually committing to doing things in particular way. Hope somebody will be able to help me :) For the record, I am currently targeting latest stable Dovecot version 2.2.5. I have an SQL DB with mail users' authentication data. Passwords are stored either encrypted via system crypt(3) or ciphered with some custom algorithm (think something symmetrical like AES, so passwords can be decrypted into plain form). I want to use this DB as both userdb and passdb backend. The issue, of course, is with ciphered passwords support. 1) Is it feasible to just implement a new password scheme for ciphered passwords support and still use stock passdb driver in Dovecot for SQL DB access? So that passwords in this scheme would be treated as PLAIN (in a sense that both cleartext and shared secret authentication methods would work). 2) Provided I implement custom password scheme for ciphered passwords, what is the best way to be capable to perform authentication against both ciphered and encrypted passwords? Ciphered and encrypted passwords are stored in different fields of SQL table (one of them is NULL when the other one is set). a) Do I define two passdb clauses with their own default_pass_scheme (equal to my new scheme or CRYPT for encrypted passwords) and use fallback to effectively check both of them? b) Do I modify SQL query so that it prefixes existing password with correct scheme (I'm not sure this will be easy enough to do)? 3) Is it mandatory to provide password generation routine for custom password scheme? When it will be used? 4) Maybe it's better to just implement a plugin that serves as both userdb and passdb driver (in other words a kind of generic authentication module)? What are advantages and disadvantages of each method - custom password scheme + stock SQL driver VS. custom userdb and passdb driver? Fortunately, I already have all the required credentials lookup and verification code. So in any case the question is only in figuring out suitable Dovecot APIs and integrating the existing code. 5) I have previously implemented similar custom authentication module for Courier-IMAP (Courier-Authlib to be precise) to use the same SQL DB. And I will need to support both IMAP servers for some time. So it is only natural to expect some generic solution to be possible. I'd like to remind that I need to be able to supply either encrypted password or deciphered plain password, or just check against them. Is it possible to do so in a common way? If so, what method should I use? I would expect SASL helping me out here, but AFAIK, both Dovecot and Courier-IMAP can only serve as SASL servers (providing authentication services), not clients. 6) I obviously care about providing enhanced security, especially against stealing mail passwords. So any additional advice or related guidelines are welcome. 7) Somewhat unrelated question: what is the best way to test IMAP (and maybe POP3 as well) server performance and compare it to another server? I'm interested in both login performance (the part I will influence) and performance with many mails in mailbox. I heard imaptest is suitable for this task. Are there any recipes or example testing scenarios you might share? ;) I would be grateful for any insight in these issues. If I chose a wrong mailing list to post to, please feel free to correct me. Thanks for your time! :) -- Best regards, Nick
