[Dovecot] Storing passwords encrypted... bcrypt?
by Charles Marcus 19 Jan '12

19 Jan '12

Hi everyone, Was just perusing this article about how trivial it is to decrypt passwords that are stored using most (standard) encryption methods (like MD5), and was wondering - is it possible to use bcrypt with dovecot+postfix+mysql (or posgres)? -- Best regards, Charles

[Dovecot] MASTER_AUTH_MAX_DATA_SIZE
by Mike Abbott 19 Jan '12

19 Jan '12

In 2.0.17 you increased LOGIN_MAX_INBUF_SIZE from 1024 to 4096. Should you also have increased MASTER_AUTH_MAX_DATA_SIZE from (1024*2) to (4096*2)? /* This should be kept in sync with LOGIN_MAX_INBUF_SIZE. Multiply it by two to make sure there's space to transfer the command tag */

Re: [Dovecot] shared folder files not displaying in thunderbird
by Eric Broch 19 Jan '12

Can anyone help me figure out why email in a sub-folder (created using Thunderbird) of a dovecot namespace will not display in Thunderbird? ... Hello, I have dovecot installed with the configuration below. One of the subfolders created (using the email client) under the '/home/vpopmail/domains/mydomain.com/shared/projects' share no longer (it used to) displays the files located in it. There are about 150 folders under the '/home/vpopmail/domains/mydomain.com/shared/projects' share all of which display the files located in them, the one mentioned used to display the contents but no longer does. What would be the reason that one folder would no longer display existing files in the email client (Thunderbird) and the other folders would? And, how do I fix this? I've already tried unsubscribing and resubscribing the folder. This did not work. Would it now be simply a matter of unsubscribing the folder, deleting the dovecot files, and resubscribing to the folder?

[Dovecot] LMTP Logging
by Mark Moseley 18 Jan '12

18 Jan '12

Just had a minor suggestion, with no clue how hard/easy it would be to implement: The %f flag in deliver_log_format seems to pick up the From: header, instead of the "MAIL FROM:<...>" arg. It'd be handy to have a %F that shows the "MAIL FROM" arg instead. I'm looking at tracking emails through logs from Exim to Dovecot easily. I know Message-ID can be used for correlation but it adds some complexity to searching, i.e. I can't just grep for the sender (as logged by Exim), unless I assume "MAIL FROM" always == From:

[Dovecot] v2.1.rc3 released
by Timo Sirainen 18 Jan '12

18 Jan '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc3.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc3.tar.gz.sig Whops, rc2 was missing a file. I always run "make distcheck", which should catch these, but recently it has always failed due to clang static checking giving one "error" that I didn't really want to fix. Because of that the distcheck didn't finish and didn't check for the missing file. So, anyway, I've made clang happy again, and now that I see how bad idea it is to just ignore the failed distcheck, I won't do that again in future. :)

[Dovecot] Dovecot unable to locate mailbox
by Jason X, Maney 18 Jan '12

Dear all, I hope someone can point me in the right direction. here. I have setup my Dovecot v2.0.13 on Ubuntu 11.10. The logs tells me that the mail location has failed as follows: ========= Jan 16 14:18:16 myservername dovecot: pop3-login: Login: user=<userA>, method=PLAIN, rip=aaa.bbb.ccc.ddd, lip=www.xxx.yyy.zzz, mpid=1360, TLS Jan 16 14:18:16 myservername dovecot: pop3(userA): Error: user molla: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/home/userA Jan 16 14:18:16 myservername dovecot: pop3(userA): Error: Invalid user settings. Refer to server log for more information. ========= Yet my config also come out strangely as below: ========= root@guyana:~# dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 3.0.0-12-server x86_64 Ubuntu 11.10 passdb { driver = pam } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } root@guyana:~# ========= My mailbox location setting is as follows: ========= cat conf.d/10-mail.conf |grep mail_location # path given in the mail_location setting. # mail_location = maildir:~/Maildir # mail_location = mbox:~/mail:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n mail_location = maildir:~/Maildir # explicitly, ie. mail_location does nothing unless you have a namespace # mail_location, which is also the default for it. ========= I am wondering how best to work around this Dovecot problem. Please help. Regards Jason.
