Are there any clues here? OK, the next step might be to try talk POP3 directly to your dovecot server, and see if it responds to some common POP3 requests. You might have to use one of telnet server 110 nc server 110 (or "ncat" or "netcat") openssl s_client -connect server:995 (if using SSL) then test with these commands USER someuser PASS their-password (Should list messages and their sizes) LIST (Should list messages and their UIDLs) UIDL (Retrieve the first message) RETR 1 QUIT If these work, then I would look at the client. If not, check the logs why it failed. > Feb 11 08:47:49 pop3(sherril): Info: Disconnected: Logged out top=0/0, \ > retr=0/0, del=0/3, size=36928 If I read this right, the client never tried to download any messages (no top, no retr). Maybe the client downloaded the UIDLs and figured it already had local copies of those messages. Joseph Tam <jtam.home(a)gmail.com>

Cache unseen count
by Jorge Carling 11 Feb '16

11 Feb '16

Dear all, Lately I am working on PHP mail account management application. It has, among others, Unread messages count column. To get the number of unread messages, I execute "doveadm search" command for each database row. The search time for single account is about 0.03 seconds. Our system has around 750 accounts, so the total loading time is currently around 20 seconds. When setting up Dovecot, I made the user_query, which is also used to store the message quota, and total number of messages stored in particular mailbox. Is there a keyword that can be included in the user_query, or some other way to maintain the unread messages count in the database? Maybe there is a way to execute a script every time a message is received, or becomes read, or unread. Kind regards,JC

Help migrating a mailbox...

Hi! i have a question for you guys, i have been playing with this issue for a while and i am a bit lost. I have dovecot 2.2.16 on a Gentoo linux server, which run a couple of email domains, linked with postfix. I have a huge (>4gb) Outlook PST file which contains a backup coming from a new user, he used to have this backup on his old email system and i need to dump it into his new email account on my server. This is just a "old" backup which needs to be kept for reference, there is no need to preserve any ID/UID/GUID whatever. So, i found the "readpst" util which is capable ot reading the PST file and dump it's contents as mbox structure. (see http://bit-vonameln.de/email-migration-outlook-dovecot-imap/) I did it and i got a 4.4gb folder with some sub-folders, attachments, and more files inside. Then i spent most of a few days trying to have dovecot digest this and import it on top of the user new email address. With no luck. I have being trying with doveadm sync but i cannot find how i need to do it. Note that: 1) there is no local user, only the mail user (user(a)hisdomain.org) 2) i use maildir, the PST has been converted to mbox 3) dovecot is compiled with maildir and mbox support I tried, for example: server # export mail_location=mbox:/path/to/mbox/converted/emails server # doveadm sync -u user(a)hisdomain.org -d doveadm(user(a)hisdomain.org): Fatal: User has no mail_replica in userdb Then i tried: server # export mail_location=/home/vmail/hisdomain.org/user/maildir server # doveadm sync -u user(a)hisdomain.org mbox:/path/to/mbox/converted/emails dsync(user(a)hisdomain.org): Error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Also tried: server # export mail_location=/home/vmail/hisdomain.org/user/maildir server # doveadm sync -u user(a)hisdomain.org /path/to/mbox/converted/emails doveadm(user(a)hisdomain.org): Fatal: execvp(/home/vmail/hisdomain.org/user/maildir) failed: Permission denied dsync-local(user(a)hisdomain.org): Error: read(remote) failed: EOF (version not received) My dovecot is configured to use "maildir", the most relevant part of my dovecot.conf is: auth_debug = no login_greeting = Dovecot ready. mail_debug = no auth_debug_passwords = no auth_default_realm = mydomain.org auth_mechanisms = plain login auth_realms = <list of my domains here> auth_verbose = no base_dir = /var/run/dovecot/ disable_plaintext_auth = no mail_uid=999 mail_gid=999 listen = * mail_location = maildir:/home/vmail/%d/%n/maildir protocols = imap sieve lmtp (i can add omitted lines if needed) either i am not undesrtanding anything, which is totally possible, or i am missing something big. If anybody on this list has any insight or suggestion, pelase advise! ps: the destination mailbox is perfectly new and empty, it's already existing and the user can successfully login, send and receive emails. Dovecot works great, and i am operating locally on the server where i uploaded the converted mbox folders. -- Willy Gardiol willy(a)gardiol.org www.gardiol.org www.trackaway.org -> Track YOUR way the way you want!

Is it possible to use redirect in a sieve to redirect to multiple addresses? if header :contains “from” “test(a)example.xn--com-9o0a { redirect “user1@example.com,user2@example.com”; } I thought this would work, But I am seeing a “redirect address is invalid: not a single addres [sic] (found ‘,’). -- I'll have what the gentleman on the floor is having.

Per-user special folder?
by Richard Platel 09 Feb '16

09 Feb '16

Hi It's possible to mark some folders as special use for IMAP in the config like: namespace inbox { mailbox Spam { special_use = \Junk } } Our webmail allows users to use an arbitrary folder for Spam, and we have this settings and we'd like to return it in from our UserDB (which is a custom dict proxy). For testing were able to set a namespace parameter like "separator" by returning: "namespace/inbox/separator" : "=", from UserDB, but can't figure out a way to set mailbox settings, "namespace/inbox/mailbox Spam/special_use" : "\Junk", for example doesn't work. Is there a way to return this setting from a UserDB query?
