imapsieve pigeonhole plugin?

How do you enable the imapsieve plugin?

wiki: Plugins/Virtual: SQL error?
by Larry Rosenman 08 Nov '16

Is one of these supposed to be imap? Note that none of the namespaces have inbox=yes. This is because for IMAP users you want the inbox namespace to have inbox=yes, but for POP3 users you want the virtual namespace to have inbox=yes. This requires setting the inbox=yes in userdb extra fields <http://wiki2.dovecot.org/UserDatabase/ExtraFields>. For example with MySQL you can can do this like: user_query = SELECT ..., \ CASE '%s' WHEN 'pop3' THEN NULL ELSE 'yes' END AS 'namespace/inbox/inbox', \ CASE '%s' WHEN 'pop3' THEN 'yes' ELSE NULL END AS 'namespace/virtual/inbox' \ WHERE ... -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 (c) E-Mail: larryrtx(a)gmail.com US Mail: 17716 Limpia Crk, Round Rock, TX 78664-7281

Pigeonhole/sieve possibly corrupting mails
by Ladislav Laska 08 Nov '16

08 Nov '16

Hi! I'm here again with a problem. I'm using dovecot as an IMAP server and LDA, filtering mail via sieve. However, few times a day I get the following error on server and my client (mutt) gets disconnected. Oct 15 20:20:29 ibex dovecot: imap(krakonos): Error: Corrupted index cache file /home/krakonos/.mbox/.imap/INBOX/dovecot.index.cache: Broken physical s ize for mail UID 149418 in mailbox INBOX: read(/home/krakonos/.mbox/inbox) failed: Cached message size smaller than expected (3793 < 8065, box=INBOX, UID=149418, cached Message-Id=<88deda0d-86f6-6115-af10-60ac06bb2d22(a)rename-it.nl>) Oct 15 20:20:29 ibex dovecot: imap(krakonos): Error: read(/home/krakonos/.mbox/inbox) failed: Cached message size smaller than expected (3793 < 8065, box=INBOX, UID=149418, cached Message-Id=<88deda0d-86f6-6115-af10-60ac06bb2d22(a)rename-it.nl>) (FETCH BODY[] for mailbox INBOX UID 149418) Oct 15 20:20:29 ibex dovecot: imap(krakonos): FETCH read() failed in=110326 out=5115197 This is on a new message (attached), and this error happens on some messages when first opened. Once I reconnect, the message always opens fine, and no old message ever causes problem. I also noticed this error, which is possibly connected: Oct 15 20:15:12 ibex dovecot: lda(krakonos): Error: Next message unexpectedly corrupted in mbox file /home/krakonos/.mbox/inbox at 546862809 The filesystem is ext4, and there are no errors in syslog or problems with any other services. I also don't access the mbox locally, and only dovecot manipulates the mbox (via imap and mailbox_command = /usr/libexec/dovecot/deliver) The postfix version is 2.2.25. I'm attaching dovecot -n and the offending message (after it's been corrected). I'd rather not publish my sieve file, but will send it privately. The offending message also contains other message I received at approximately the same time. Any hint's on what could be wrong? -- S pozdravem Ladislav "Krakonoš" Láska http://www.krakonos.org/

connection to storage server failed
by ＠lbutlr 08 Nov '16

08 Nov '16

I am getting this error after updating to dovecot2-2.2.26.0_1 under FreeBSD 10.2 when a user tries to login via roundcube webmail. I am able to login via my own mail client and there is no error in the log when roundcube fails to login. I stopped dovecot, removed all the dovecot files from the maildir folders and restarted dovecot, but get the same error. <https://help.directadmin.com/item.php?id=473>

Backing up and Importing IMAP folders
by Jerry 08 Nov '16

08 Nov '16

I am running Dovecot with Postfix on a FreeBSD machine. There are problems with the drive and I cannot depend on it. Dovecot saves all mail in IMAP format. I want to back up the mail folders, install a new HD, install the latest FreeBSD OS and then reinstall my programs. Reinstalling Dovecot is simple, but how do I reinstall the IMAP folders? Can Dovecot backup the folders onto a CD and then import them when I reinstall it? My mail is kept under “/var/mail/vmail”. Should I just back up that entire directory structure and then restore it later? Thanks! -- Jerry

This is on 2.2.26.0. Escaping was only added to auth code, not logging one, right? -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

logging TLS SNI hostname
by Arkadiusz Miśkiewicz 08 Nov '16

08 Nov '16

Is there a way to log SNI hostname used in TLS session? Info is there in SSL_CTX_set_tlsext_servername_callback, dovecot copies it to ssl_io->host. Unfortunately I don't see it expanded to any variables ( http://wiki.dovecot.org/Variables ). Please consider this to be a feature request. The goal is to be able to see which hostname client used like: May 30 08:21:19 xxx dovecot: pop3-login: Login: user=<abc>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, mpid=17135, TLS, SNI=pop3.somehost.org, session=<hfS9Qwk03sBTBnrN> -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )
