Hello Sascha, sieve scripts are quite easy, see Steffen's example. I think what you want your script to do is: With any detail part, lowercase it, file message into detail folder, create as necessary. Something like auto-variables in Makfiles, where the rule gets its value from the target, e.g. -- peter

Deafness
by Steffan Cline 29 Jul '15

29 Jul '15

I’ve started in the last day or so having issues where users get a timeout when connecting to dovecot. The iPhone interprets this as an auth issue but re-entering the password makes no change. Outlook will either just not connect to it at all or it gives an error to re-enter the password also with no change. This happens within an hour of a "service dovecot restart". I’m using CentOS 6 with dovecot 2.0.9 from the centos repos. There’s nothing visible in the logs. Suggestions of what to check for? Thanks, Steffan

dbox: message internal date
by Francesco 29 Jul '15

29 Jul '15

Hello everyone and thanks in advance for the help :) I'm trying to figure out where does dovecot store the message internal date when using single dbox storage format. In Maildir format, the internal date is determined by the actual date of the file on the filesystem, but in dbox it doesn't seem to be the case. I'm looking forward for a way to modify a message internal date when on a dovecot instance running dbox storage engine, maybe anyone knows if it's possible and how to accomplish this? Again, thank you for the help Sincerely Francesco

sharing INBOX with ACL -> share all folders
by Marco Giunta 28 Jul '15

Hi at all, I have a problem with ACL; I want to share INBOX and Sent folder to an other user, but when I configure ACL on INBOX, all folders are shared (Sent, Junk, Draft, Trash, etc) # doveadm acl get -u janedoe INBOX ID Global Rights user=johndoe expunge insert lookup post read write write-deleted write-seen # doveadm acl get -u janedoe Sent ID Global Rights user=johndoe expunge insert lookup post read write write-deleted write-seen # doveadm acl get -u janedoe Trash ID Global Rights # doveadm acl get -u janedoe Drafts ID Global Rights # doveadm acl get -u janedoe Junk ID Global Rights # doveadm mailbox list -u johndoe Trash Junk Drafts Sent Archives Archives.2015 Other Users Other Users.janedoe Other Users.janedoe.Junk Other Users.janedoe.Drafts Other Users.janedoe.Sent Other Users.janedoe.Trash Other Users.janedoe.INBOX INBOX If I remove the INBOX ACL, only 'Sent' folder is shared, as expected: # doveadm acl delete -u janedoe INBOX johndoe # doveadm mailbox list -u provahe Trash Trash.saved-messages Junk Drafts Sent INBOX_spam Archives Archives.2015 Archives.2015.INBOX_spam Other Users Other Users.janedoe Other Users.janedoe.Sent INBOX My Dovecot instance use a single user, and all my mailboxes use standard maildir files: drwx------ 9 vmail mail 0 Jul 28 10:59 . drwx------ 12 vmail mail 3864 Jul 28 09:39 .. drwx------ 2 vmail mail 0 Jul 28 09:51 cur -rw------- 1 vmail mail 0 Jul 28 10:59 dovecot-acl -rw------- 1 vmail mail 16 Jul 28 10:59 dovecot-acl-list -rw------- 1 vmail mail 1448 Jul 28 09:51 dovecot.index.cache -rw------- 1 vmail mail 1016 Jul 28 09:52 dovecot.index.log -rw------- 1 vmail mail 113 Jul 28 09:51 dovecot-uidlist -rw------- 1 vmail mail 8 Jul 28 09:39 dovecot-uidvalidity -r--r--r-- 1 vmail mail 0 Jul 28 09:39 dovecot-uidvalidity.55b731ac drwx------ 5 vmail mail 0 Jul 28 09:39 .Drafts lrwxrwxrwx 1 vmail mail 5 Jul 28 09:39 .INBOX_spam -> .Junk drwx------ 5 vmail mail 0 Jul 28 09:39 .Junk -rw------- 1 vmail mail 16 Jul 28 09:39 maildirsize drwx------ 2 vmail mail 0 Jul 28 09:51 new drwx------ 5 vmail mail 0 Jul 28 09:50 .Sent -rw------- 1 vmail mail 37 Jul 28 09:39 subscriptions drwx------ 2 vmail mail 0 Jul 28 09:51 tmp drwx------ 5 vmail mail 0 Jul 28 09:39 .Trash any clue to solve my problem ??

Importing mbox archives into a inbox?
by Paul Hoffman 27 Jul '15

27 Jul '15

Greetings from a dovecot newbie. I have a bunch of mailing list archives (in mbox) format that I want to dump into the inbox for a particular account on the system. I want them to retain all of their information, particularly the date. I'm not seeing how to do this, but I could be missing it. Is this LDA or LMTP with some command-line options I'm not seeing? --Paul Hoffman

POP3 getting previously delivered messages.
by Jas Reehal 24 Jul '15

24 Jul '15

Hi All, This is my first post to this list. I have recently upgraded to dovecot version 2.2.10. 1. I have one POP3 user who does not want to delete his email on the server. 2. He has accumulated over 19000 messages, and the 'dovecot.uidlist' file has more than 19000 lines! 3. Occasionally now when he has received one or more new emails, and his email client does a 'get new mail' operation (POP3) he begins to receive email he has already received previously. last time this happened all 19000+ messages were delivered again, leaning to duplicate entries in all his mailboxes. I have reproduced this issue with a dummy email account with a POP3 client, leaving all messages on the server. I have delivered 20000 messages to this email account, each about 1.3k ins size and each with .... Subject: Message number <n> Body containing "Message number <n>" where <n> is 1 to 20000 now occasionally if I send another message to this email account, and then check for new messages using a POP3 client I get more messages downloaded than I expect! The 'dovecot.uidlist' file is not corrupt, but I beleive due ti it's size (number of lines) the is an issue on compiling a ' POP3 drop-list'. I have attached a file 'dovecot-a.txt' which shows the 'dovecot -a' output from my server. Based on what I have investigated I believe that this issue may not be correlated with a migration to version 2.2.10, but more to do with the number of messages retained on the server. Is there anyone who has any insight into what is happening and if there is any remedy, perhaps a "pop3_client_workarounds =" or other POP3 or UIDL directive in the conf files? The user is stubbornly resisting migration to IMAP, because of the time and effort he says will be required to replicate his organised filing/storage of messages on the server.

possible patch for ACL SQL ERROR: duplicate key value violates unique constraint "user_shares_pkey"
by Steffen Kaiser 24 Jul '15

24 Jul '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm using Postgres as dict backend now and then I get this error, when someone changed ACLs, actually for some reason some users, who get permission from other users, get this error quite often: dict: Error: sql dict: commit failed: ERROR: duplicate key value violates unique constraint "user_shares_pkey" (query: INSERT INTO user_shares (dummy,to_user,from_user) VALUES ('1','user1','user2')) It looks like that this error is triggered, when a MUA is connecting to Dovecot after ACLs had been changed and opens several mailboxes at once. So two or parallel Dovecot instances try to insert the record simultaneously. With a similiar technique to the quota problem, I added a trigger. The idea is to use the condition dummy ISNULL to detect, that the function was triggered from the INSERT of the function itself, hence, breaking the recursive triggers. This assumes that dummy is never NULL from Dovecot. The same applies to anyone_shares, just remove the to_user field from the function. Does somebody see something wrong with my hack? ============= CREATE FUNCTION insert_sharing() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN IF NEW.dummy IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert return NEW; END IF; LOOP UPDATE user_shares SET dummy = NEW.dummy WHERE from_user = NEW.from_user AND to_user = NEW.to_user; IF found THEN -- updated and inserted RETURN NULL; END IF; BEGIN INSERT INTO user_shares (from_user,to_user,dummy) VALUES (NEW.from_user,NEW.to_user,NULL); --- return NULL; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; -- Update dummy after INSERT END LOOP; END; $$; CREATE TRIGGER insertsharing BEFORE INSERT ON user_shares FOR EACH ROW EXECUTE PROCEDURE insert_sharing(); - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBVbHxJXz1H7kL/d9rAQIn5gf/dNMQKmmigGrbccGQQrsGU66B6OHvTY7L 1vyh8hgr985KNk2/Ws/usLnAqpl5jhpo8kVPLI8TqcGYLAS/67TOIFrwLKAEBU96 e+QpbqqiSm66mZwWOQZgCI63+Fh7fdBUMREL6UqGleFF1GrzNnjmX4MGecbpu/L9 gQMAGUG++/S+ka9S6B275RXIj9DvWzq/oYqJ1M1grGckUxXfDk5szLyvuIJ981At 20qaCHEIlIOlkQ0ttE4W+RWkkYS2rMJvCzQelF4pcm6vaxhXxvqUryzmy9pv+UUT osqS6igWt7BPXF7ku8+rKYVp/qPZrh9IWXMsajr/2nI+V5gRb6u2ow== =gb1P -----END PGP SIGNATURE-----
