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.

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

can't create folders under shared mailbox's INBOX
by luke.bigum＠lmax.com 08 Apr '15

Hello, I have a namespace / ACL problem with shared mailboxes that I can't figure out. I have a local user tam(a)crm.yb.lmax that shares it's INBOX and all other folders with on LDAP group.

ACL syntax for setting specified folders within Maildir/ read-only for owner
by kepa 08 Apr '15

08 Apr '15

Hi, I have dovecot (2.2.16, see dovecot -n at end) installed to /opt on CentOS 6 for access on a local network. I would like to create an archival mail account which will reduce the primary account file size and still make older emails easily accessible. How can I set specified folders in this Maildir read-only with ACL? For example, I included this in the dovecot-acl file to specify protected folders in the archives@ Maildir but it did not work: "Email 2013/*" user=archives lrs "Email 2014/*" user=archives lrs Also tried this on folders without spaces with no success (the folders were still delete-able by the user via the Thunderbird client). Each "Email..." folder has several child folders that should also be read-only. BTW, what is the maximum size for a Maildir that Dovecot can comfortably handle? Thanks!

Dovecot keeps creating info files in mail directory instead of home
by Jeffrey 'jf' Lim 08 Apr '15

08 Apr '15

I've been trying to troubleshoot this for a while now, and I'm really at a loss. My userdb is set up correctly to return home, and mail, and a test with 'doveadm user' verifies this: # doveadm user user@domain field value uid 1000 gid 1000 home /var/domain/user mail maildir:/var/mail/user@domain I've reloaded, restarted, stopped and started dovecot again - and even deleted the info files in the mail directory just to be sure - but each and every time I log in with imap, dovecot recreates the files again (dovecot.index.log, dovecot-uidlist, etc.) in the mail directory instead of home. I've even made sure just in case that the home directory is accessible to all, and chmod 777, but nothing gets created there. And I dont get any errors at all in the logs. I'm on the latest version (2.2.16). -jf -- He who settles on the idea of the intelligent man as a static entity only shows himself to be a fool.

Authentication with Samba using Kerberos fails
by Justin Clacherty 08 Apr '15

08 Apr '15

Hi, I've been having some problems getting GSSAPI authentication going against a samba (4.2) server and am hoping someone can point me in the right direction. I've searched through Google and haven't managed to find a solution yet. I followed the config instructions at http://wiki2.dovecot.org/Authentication/Kerberos and run through the testing. Testing from the server with telnet does as expected i.e. I get the "+" after I try "a authenticate GSSAPI". However, when I go to test from Thunderbird on while logged in on a Windows PC joined to the domain authentication fails and I see the following in mail.log (I'm running Ubuntu 14.04.2 LTS).
