Calendar and address book with Dovecot
by mimicafe＠gmail.com 10 Apr '15

10 Apr '15

Hi all I recently install Postfix and Dovecot, and so far so good. My assumption was that calendar and address book (similar to Gmail calendar or address book) are part of Dovecot. However I do not see anything concerning them in any of the docs I have read so far. What other software (ideally open source, free) do I need in other to have Calendar and address book so my users can manage their contact on their phones or computer? I have looked at Roundcube already, but my requirement is not necessarily to provide web mail. Thanks Mimi

pop3 retr responses too large lines - Fails with current python's poplib
by Guillermo M. Narvaja 10 Apr '15

10 Apr '15

Since December 2014, clients using the Python poplib library (getmail in my case) started to limit the line length of RETR and other command responses sent from the server to 2048 bytes: See https://bugs.python.org/issue16041 (Included at least in Python-2.7.9) Dovecot doesn't have line split in the POP3 module, so Python fails to retrieve messages with long lines. RFC 1939 says: " Responses in the POP3 consist of a status indicator and a keyword possibly followed by additional information. All responses are terminated by a CRLF pair. Responses may be up to 512 characters long, including the terminating CRLF. " I think dovecot-pop3 should split it's output in lines of at least 512 characters. Or at least it should have a "pop3_max_line_length" setting (like "imap_max_line_length"). Server side: # dovecot --version 2.2.13 Client side: # python --version Python 2.7.9 # getmail --version getmail 4.47.0 Temporary workaround (on client-side): --- poplib.py.orig 2015-04-08 18:46:48.280879211 -0300 +++ poplib.py 2015-04-08 18:26:01.288556028 -0300 @@ -36,7 +36,7 @@ # reading arbitrary length lines.

FYI: Some 'fun' unlinks with random memory space references
by Jeroen Massar 10 Apr '15

10 Apr '15

Hola, Dovecot: 2.2.16 (6bde7868cffd) That is the rename-it 2:2.2.16-1~auto+43 edition. In the beginning of syncing it caused scary things like: Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(OX/dbox-Mails/u.10672) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(ox/mailboxes/INBOX/dbox-Mails/u.10927) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(OX/dbox-Mails/u.10839) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(OX/dbox-Mails/u.10656) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(11147) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(OX/dbox-Mails/u.10637) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(OX/dbox-Mails/u.10807) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(<80><A5><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(<B0><A6><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(<E0><A7><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(#020<A9><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(@<AA><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(p<AB><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(<A0><AC><C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink(Э<C8>) failed: No such file or directory Apr 9 16:24:08 mail dovecot: dsync-server(username): Error: unlink() failed: No such file or directory Might want to put a check before that unlink that nothing dirty is in the buffer... I would not be surprised if this was related to a broken index, as the other side effect I saw during this sync was an ever-expanding maildir (read: sdbox), multiplying itself during sync, keeping large amounts of the the .temp.<xxxx> in the dir, never moving them to a final directory. That was resolved by stopping dovecot, then deleting the broken sdbox (backups++) and performing a 'dovecot force-resync -u user Folder' on the source. Maybe there was a race somewhere while syncing the large amount of data over; seems that everything is okay now though. Greets, Jeroen

sa-learn with remote Dovecot folders
by Andreas Kasenides 10 Apr '15

10 Apr '15

Hi all! The set-up I have is a classic one: 1. one or more Dovecot relay/directors Postfix SMTP servers in DMZ 2. one or more backend IMAP/SMTP servers on the inside network 3. There may or may not be separate incoming or outgoing designated SMTP servers. Now the desired functionality is (of course): 1. relay machines receive messages from outside AND inside 2. relays check for all the bad things (spam, viruses etc). 3. for incoming messages relays check for valid local users and reject messages for invalid users 4. after all checks are done incoming messages are transferred to the backend systems where they are accessed via the Dovecot directors While all the above works nicely, the problem I have is how to train my spamassassin (used by amavisd) on the front ends when all messages are on the back ends. Of course transferring the spam detection procedures internally is not such a great option.Am I missing something? I tried googling for info but nothing substantial turned up. Thanks. -- Andreas Kasenides Senior IT Officer Dept. of Computer Science, University of Cyprus Tel: 22892714, Fax: 22892701 (5B4ANK)

gmail-migration: archived mails in \ALL
by Peer Heinlein 10 Apr '15

10 Apr '15

Hi, I don't completly understand http://wiki2.dovecot.org/Migration/Gmail I can't find the documentation for the -a and the -F Flag. I'd like to migrate ONLY archived mails from an existing gmail-Account. So I'd have to import all Mails from the \ALL-Folder that does NOT have any virtual folder flags set. I tried to use this command: doveadm -D -o imapc_user=user(a)example.com -o pop3c_user=user(a)exampe.com -o imapc_password=secret -o pop3c_password=secret -o imapc_host=imap.googlemail.com -v backup -m '[Gmail]/Tutti i messaggi' -F '-$GmailHaveLabels' -x \Flagged -x \Junk -x \Trash -x \Important -R -u user(a)example.com imapc: But it looks like it's importing too many mails and not only the archived mails without Flags. How do I have do understand -F '-$GmailHaveLabels ?? Is it "that NOT have $GmailHaveLabels"? And: Is there any better way to address the \ALL-Folder? I can use "-x \All" to exclude that folder, but it looks like I can't use "-m \All" to select that folder. We're a little bit in hurry since Google will stop its service this weekend. Any fast help would be appreciated.

Sieve, multiple addresses, and variables
by Andrew Sullivan 08 Apr '15

08 Apr '15

Hi, I have another sieve question, this time about setting variables. I join a lot of mailing lists at ietf.org. I thought it'd be handy to filter these all into a common folder and then into individual folders, without having to configure each mailing list independently. So wrote this (this is just a part, obviously): require ["envelope", "variables", "date", "fileinto", "mailbox" ]; if address :is :domain "to" "ietf.org" { if address :matches :localpart "to" "*" {set "lopart" "${1}";} } elsif address :is :domain "cc" "ietf.org" { if address :matches :localpart "cc" "*" {set "lopart" "${1}";} } else {set "lopart" "generic-list-box";} fileinto :create "ietf.${lopart}-in"; stop; } Now, this works, unless someone sends a To: line like this: To: ajs(a)crankycanuck.ca, listname(a)ietf.org The problem in that case is that you _do_ get a match, but the bit "if address :matches :localpart "to" "*" {set "lopart" "${1}";}" ends up putting this in a mailbox ietf.ajs-in, when what is the mailbox ietf.listname-in. I thought that allof(if address :matches :localpart "to" "*", address :matches :localpart "to" "*") {set "lopart" "${1}";}, would solve this, but it doesn't seem to. The localpart matching catches the ajs(a)crankycanuck.ca address anyway, which surprised me. Am I dim, am I not understanding something about how to do this, or is this really impossible? Thanks, A -- Andrew Sullivan ajs(a)crankycanuck.ca

Need a bit of help with the antispam plugin

can't create folders under shared mailbox's INBOX
