Yes, it does. I wish the documentation on the Wiki was easier to find gems like this. Thank You!

[Dovecot] PAM and user@domain login?
by Larry Rosenman 16 Nov '13

Is there a way with 2.2.6 to have the system do a PAM login for user when presented with login user@domain pass from the IMAP services? I have a stupid android client that wants to use user@domain but doesn't have an option to pass just user.....

[Dovecot] Replication Setup
by springy 16 Nov '13

16 Nov '13

Hi, I am attempting to setup replication between two hosts running Centos 6.4 and Dovecot 2.2.5. My users are real unix users, so I am trying to run the replication as root user, so that it has the appropriate permissions to run. I have two users at present syd1 and syd2, and the two hosts are called syd1 and syd2 as well. When I start Dovecot with the settings below, nothing happens, and the two mailboxes remain un-synced. There are no errors in the log, just Dovecot starting successfully. I have attempted to run the dsync command manually from syd1: ssh -q -o StrictHostKeyChecking=no -i /home/vmail/.ssh/id_ecdsa root@syd2 doveadm dsync-server -usyd1 and I get the following in response, but this might be normal: VERSION dsync 3 1 Hhostname sync_ns_prefix sync_box sync_box_guid sync_type debug sync_visible_namespaces exclude_mailboxes send_mail_requests backup_send backup_recv lock_timeouno_mail_sync no_backup_overwrite Smailbox_guid last_uidvalidity last_common_uid last_common_modseq last_common_pvt_modseq changes_during_sync Nname existence mailbox_guid uid_validity uid_next last_renamed_or_created subscribed last_subscription_change Dhierarchy_sep mailboxes dirs unsubscribes Bmailbox_guid uid_validity uid_next messages_count first_recent_uid highest_modseq highest_pvt_modseq mailbox_lost cache_fields have_guids have_save_guids Atype key value stream deleted last_change modseq Ctype uid guid hdr_hash modseq pvt_modseq save_timestamp add_flags remove_flags final_flags keywords_reset keyword_changes Rguid uid Mguid uid pop3_uidl pop3_order received_date stream cname decision last_used .

[Dovecot] Dovecot antispam unable to call dspam since dovecot upgrade to 2.X
by Guillaume Hilt 15 Nov '13

Hello, Running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam, i finally upgraded to dovecot 2.X. I'm running dovecot 2.2.6, dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429.

[Dovecot] Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Hello: I'm loosing my mind trying to classify my outgoing messages with sieve-test (2.0.9, centos 6.4). It came to the point I think it's not even possible with a sieve script. I need to classify my outgoing messages in three folders: 1- To my department (@dept.example.com) 2- To my company (@example.com, @anyotherdept.example.com) (anyotherdept.example.com as in a way to say "any other domain that ends with 'example.com', but not 'dept.example.com'") 3- To the rest of the word (@any.other.domain) The problematic requirement is I need to make a copy in EVERY IMAP folder that applies. For instance: for an email such as ---- From: myuser(a)dept.example.com To: user(a)dept.example.com, user(a)example.com, user(a)other.domain ... ---- I need to make a copy to all folders: Dept (because of user(a)dept.example.com) Company (because of user(a)example.com) and Rest (because of user(a)other.domain) Rule for #1 is simple: ----- if address :matches :domain "To" "dept.example.com" { fileinto: "Dept"; } ----- Rule for #2, I don't know how to declare it: I don't know how to make a rule that matches "example.com" (or anyotherdept.example.com) and not "dept.example.com". if allof(address :matches :domain "To" "example.com", not address :matches :domain "To" "dept.example.com") { fileinto: "Company"; } ... doesn't work, because user(a)dept.example.com matches (address :matches :domain "To" "example.com"), but it doesn't matches (not address :matches :domain "To" "dept.example.com"). "user(a)example.com" matches both conditions, but sieve-test stops on the first email address with a "not matches" As for Rule #3: I don't know how to do it either, it should be the same as Rule #2, (with different parameters of course). A sieve script should be capable to do this, but it seems that I'm loosing something. Does any one knows how to do this? Kind regards Yanko PS: English is not my native language. Please forgive me any mistakes/misspellings/etc I made.

[Dovecot] Fwd: Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Ok, let simplify a little bit the problem: Forget about outgoing or incoming mail. Forget about IMAP or SMTP. You have a ton of emails in raw form (RFC-XXX, don’t remember the exact number right now) you want to classify… and you think: “Sieve is a language made to do exactly that kind of task… If only I could use the same mechanism dovecot-lda uses! Oh, wait… “sieve-test –e” does exactly that!!! I could use it!!!”… but so far… no success. Now, a little more context. I want to leave a copy (a historical record) of every email (work related) I received/sent. The processing/classification doesn’t have to be in real time, it can be on “down time/offline/later/scheduled”. Sent messages are hard, because of the several senders and the several copies on several folders. But I can work around it, with various tricks (bcc, different headers, etc.) and adjusting the processing sieve script. I can train myself –The interest is mine after all!-, and that’s OK. But I can’t train other people to suit my needs. And received messages are JUST AS HARD. Because I want to classify them using the same rules. I also want to keep context, to record all things work related, not only what I said, but also what was said by others, using the same rules (which by the way, are many more than the restricted example I posted). Besides, I want the PC do all the work for me, not the other way around. I think “Sieve must be capable of doing it! This is the kind of things sieve was designed for!” is a reasonable idea. But so far, no success… :-( Now, let me see all the replies in detail...

[Dovecot] Establing a GMail like workflow
by Florian Lindner 15 Nov '13

15 Nov '13

Hello! I'm about to migrate my mails from GMail back to my self hosted solution, using Dovecot imap server. I really liked gmail workflow: - (Almost) all mail goes to inbox. - Most mail is read and not important anymore, it is archived and moved to "all messages". - Inbox stays more or less clean, with only mails that are still of some interest. - Mail (except Spam) is never deleted, just archived. How can I achieve such a workflow using Dovecot and some MUA (Roundcube and probably KMail). - I can simply delete messages that I want to archive, Trash will never be purged. Problems: Some mail clients have settings like "Purge Trash at exit", so my mail is always in danger of being deleted accidently. Futhermore it does not really have the semantics of what I am actually doing. - Instead of deleting messages for archiving, move them to some Archiv folder. Since archiving is a very frequent action this involves much more cliks in the MUA than just deleting. Or some configuration change in the client. How would you do that? I'm also open to entirely different suggestions! What I want are basically these things: - Never delete legitimate mail - Use the Inbox as a workspace for mails that are still of some interest. This can also be quite old mail, time based archiving does not work. - Have some kind of mail archive. Thanks! Florian

[Dovecot] Dovecot login slow
by Marc Perkel 15 Nov '13

15 Nov '13

Can't figure out why the login is slow. I telnet to port 143 on localhost. I type: 0 login user password Takes about 10 seconds and it lets me in. I'm using MYSQL and it's a small indexed database on a fast server so it's not the mysql query that's slowing it down. At least I don't think it is. But - kind of stumped. Just wondering if there's something obvious I'm overlooking.

[Dovecot] Executing a wget? or clicking on a link in inbound email?
by Voytek 14 Nov '13

14 Nov '13

I use Dovecot, but all I know about Dovecot is that's it is an IMAP server, and, I know that it includes lots of other stuff that I see discussed on this list, but I know nothing about it. I have a situation that, maybe once a week, I get an html only email that contains 3 clickable links. I would like, on receipt of such email, auto click the first link (perhaps execute a wget to do so? or ?) Can something like this be done, which of the tools, what docs to look at? link is like so http://llll.domain.tld/irportal?id=a0000000006hWO4AAM0000000000KlOrcAAF1111… Dovecot 2.09 Centos (apologies for blank post I've just sent) -- Sent from Kaiten Mail. Please excuse my brevity.
