This is the first part for Mozilla Thunderbird setup. I've seen this work both on Win32 systems and linux systems (mainly Linux Mint). There's a part on pop3/smtp. I am sure you can skip that and do your own magic for those two protocols : Pre-Installation, Wizard Configuration -------------------------------------- During initial Thunderbird startup, the admin is greeted by a welcome window named “Mail Account Setup” Click on Cancel Installation ------------ Click on “Edit” -> “Account Settings” New window pops up Click on “Add” New window pops up Fill in “Description” (e.g. “Name Surname mailbox”) On “Server Name” enter the IP address (e.g. 192.168.3.5) On “Port” enter the SMTP port (e.g. 25) On “Security and Authentication” → “Connection Security” enter none On “Authentication Method” choose Password transmitted insecurely On “Username” enter the users' username including the FQDN (e.g. name(a)domain.gr) Click on OK From “Edit”, click on “Account Settings” From “Account Actions” click on “Add Mail Account” New windows pops up Enter in the same name for “Your name” Enter in the same e-mail address for “Email address” On “Password” enter in users' password Click on “Continue” then without waiting click on “Manual Config” Once “Manual Config” is clicked, thunderbird will allow the admin to perform additional configuration tasks For “Incoming” the admin will choose “IMAP”, Server Hostname will be set to the servers' IP address (again, 192.168.3.5) From “Port” choose “993” From “SSL” choose “SSL/TLS” From “Authentication” choose “Autodetect” For “Outgoing” the admin will let the “SMTP” option For “Server Hostname”, choose the same IP address (e.g. 192.168.3.5) For “Port” choose “25” For “SSL” choose “None” For “Authentication” choose “Normal Password” On the Username field, enter the full user name, e.g. “user(a)domain.xn--gr-02t Click on “Re-test” Click on “Create Account” Check on the “I understand the Risks” checkbox Click on “Create Account” Click on “Confirm Security Exception” Click on “OK” Hope this helps and best regards, Spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] dovecot-antispam and Thunderbird, Outlook, etc.
by Eddy Ilg|univation 04 Sep '12

04 Sep '12

Hi, In the documentation of dovecot-antispam it is mentioned that moving mails out of the spam folders trains them as non-spam. I.e. thunderbird automatically deletes old spam messages (after a time limit, i.e. 14 days). Will this also train the old spam messages as non-spam? Cheers, Eddy

[Dovecot] Imap Ghost folder
by Sascha Zucca 03 Sep '12

03 Sep '12

Hi list, i have a strange "ghost" folder in my subscription list and just can't find out how to get rid of it. It seems to be someones Inbox, but it doesn't tell me whose. Here's a screenshot of Open-Xchanges Web-GUI: /http://s9.postimage.org/6aohh97ov/iehadjhb.jpg / As you can see there is an unamed folder just under Freigaben (Shares). In Thunderbird: /http://s12.postimage.org/z0n82k2u5/bjddgefg.jpg/ Now the Folder is "INBOX"...But it is noones Inbox, as the corresponding user (amazon e.g.) should be a prefix-folder right before the share. some output over Telnet: 1 lsub "" "*" * LSUB () "/" "INBOX" * LSUB () "/" "INBOX/Amazon" * LSUB () "/" "INBOX/Bestellung" * LSUB () "/" "Drafts" * LSUB () "/" "Sent Items" * LSUB () "/" "Spam" * LSUB () "/" "Trash" * LSUB () "/" "Freigaben/amazon/INBOX" 1 OK Lsub completed. 1 list "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Sent Items" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/Amazon" * LIST (\HasNoChildren) "/" "INBOX/Bestellung" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\Noselect \HasChildren) "/" "Freigaben/amazon" * LIST (\Noselect \HasNoChildren) "/" "Freigaben/" * LIST (\HasNoChildren) "/" "Freigaben/amazon/INBOX" 1 OK List completed. This looks a bit strange to me: * LIST (\Noselect \HasNoChildren) "/" "Freigaben/" But i don't know really if that is the ghostfolder. finally here's the interesting part in my dovecot.conf: / namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = Freigaben/%%n/ location = maildir:/var/mail/vhosts/%%d/%%n/:INDEX=/var/mail/vhosts/%%d/%%n/ subscriptions = no list = children inbox = no } / Any idea how to banish the ghost in the machine?

[Dovecot] exclude a folder for lazy expunge (move to trash)
by Angel L. Mateo 03 Sep '12

03 Sep '12

Hello, I'm configuring lazy expunge plugin to act as a kind of backup of my user's emails. I'm getting a little problem because a lot of my users use "move to trash" behaviour in their email client (most of them are using thunderbird which has no option to hide deleted messages and is a hassle working with mark as deleted with it). The problem combining move to trash with lazy expunge is that messages are stored in the expunge namespace twice, first when it was deleted from the original folder and the second when is deleted from the trash. So... is there any way to exclude trash folder from lazy expunge plugin, so mails are stored in the expunge namespace only when they are deleted from their original folder and not from the trash? Another idea... We are purging trash folders with a cron running "doveadm purge" commands. Is there any way to run this command disabling lazy expunge plugin? Any other idea not to duplicate these emails? -- Angel L.

[Dovecot] [Postfix] SASL Auth. using Dovecot with password forwarding proxy configuration
by Adi Pircalabu 02 Sep '12

02 Sep '12

Hi, I'm relatively new to Dovecot and I did a bit of search but couldn't find a possible solution for the particular setup I'm working on. Basically I have an SMTP/POP/IMAP proxy setup running Postfix & Dovecot. IMAP/POP authentication is done using the password proxy feature, where the login credentials are passed to the backend server after a db lookup, which does the actual authentication. The POP/IMAP part is working fine. What I'm trying to do is to use Dovecot SASL implementation in Postfix to do SMTP authentication in a similar manner. The problem I have with my current configuration is that SMTP authentication succeeds if only the username matches, because password forwarding works if the authentication succeeds with any given password, as documented at http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy My question is, given the above: is there a way to get SMTP authentication properly in this scenario? The way I see it now, Dovecot SASL accepting the login if only the user matches isn't quite "complete", the auth process should go further and authenticate against the backend server, same as for POP/IMAP connections. Does this requirement make any sense? Maybe I'm missing something in Dovecot configuration to get the SMTP authentication work in password forwarding mode, few pointers will be highly appreciated. PopBSMTP is not an sensible alternative in my case. Here's my configuration, plus some dovecot auth_debug log entries. As you can see, SMTP authentication succeeds with any given password. ---Dovecot--- dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.centos.plus.x86_64 x86_64 CentOS

[Dovecot] Special Folder Mocking
by Eddy Ilg|univation 02 Sep '12

02 Sep '12

Dear Dovecot List, probably everyone knows the problem that different clients use different names for "Sent", "Trash" and so on. A simple question: Isn't it possible to advertise one imap folder with different names, depending on the client? E.g. if the client is Outlook, show the "Sent" folder as "Sent Elements" (translated from german) and if the client is Thunderbird, show the "Sent" folder as "Sent"? Best regards, Eddy Ilg
