backup mails from alternate storage
by Lars Täuber 04 May '15

Hi there! It seems that # doveadm backup -v backup -fu $MUSER mdbox:"$BKPDIR/$MUSER/mdbox" doesn't backup all messages stored in alternate storage. mail_location = mdbox:~/mdbox:ALT=/srv/mail/slow/vmail/%n/mdbox I don't know how to debug this. The sizes of the mailboxes in the filesystems of user C are strange: ~/mdbox: # du -sm 2169 ALT: # du -sm 25252 backup: # du -sm 2658 This is with dovecot 2.2.9 on Ubuntu x86_64 14.04.2 LTS. Is this a bug or am I doing something wrong? How can I test if messages stored in the alternate storage are successfully backed up? Thanks Lars

Hello, Since recently (not sure when), dsync stopped working. dsync -u klink mirror XXXX dsync-local(klink): Error: remote: dsync-server: invalid option -- 'l' dsync-local(klink): Error: remote: doveadm dsync-server [-u <user>|-A] [-S <socket_path>] dsync-local(klink): Error: read() from worker server failed: EOF I did not change anything on my setup but dovecot was upgraded (debian stable).

Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini
by Robert Chalmers 02 May '15

Running postfix+dovecot+mysql on a mac-mini, and trying to solve this puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't configured in? You can see from the output of the samples shows in the first case, that SHA512-CRYPT seems to be Unknown. The code I used is from a Linux based tutorial on setting up Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart from this bit. There are some others unknown as well. The codes used to create my database of passwords follows these output examples. MacMini:~ robert$ sudo doveadm pw -s SHA512-CRYPT -p 123456 Fatal: Unknown scheme: SHA512-CRYPT MacMini:~ robert$ sudo doveadm pw -s SHA512 -p 123456 {SHA512}ujJTh2rta8ItSm/1PYQGxq2GQZXtFEq1yHYhtsIztUi66uaVbfNG7IwX9eoQ817jy8UUeX7X3dMUVGTioLq0Ew== MacMini:~ robert$ sudo doveadm pw -s SHA256 -p 123456 {SHA256}jZae727K08KaOmKSgOaGzww/XVqGr/PKEgIMkjrcbJI= MacMini:~ robert$ sudo doveadm pw -s MD5 -p 123456 {MD5}$1$.mAQzPhO$6v/WxTUt.Y1lhopkMarEb0 MacMini:~ robert$ sudo doveadm pw -s MD5-CRYPT -p 123456 {MD5-CRYPT}$1$gNkYwx/o$3nQLmUIPOBmZdR/e/EXFV1 MacMini:~ robert$ sudo doveadm pw -s BLF-CRYPT -p 123456 Fatal: Unknown scheme: BLF-CRYPT MacMini:~ robert$ sudo doveadm pw -s SHA512 -p 1pass66U! {SHA512}EuuO6BAt+bgzXIOw7XIdiVBFwdEZ2tGqHOJ/DSTSkD+ikw7GQQo+KtHSta7p3KNv2AEVKtfOuyl5UeCEqnKogg== MacMini:~ robert$ sudo doveadm pw -s SHA256-CRYPT -p 1pass66U! Fatal: Unknown scheme: SHA256-CRYPT MacMini:~ robert$ mysql --version mysql Ver 14.14 Distrib 5.6.19, for osx10.9 (x86_64) using EditLine wrapper MacMini:~ robert$ cd My MySQL Version: mysql Ver 14.14 Distrib 5.6.19, for osx10.9 (x86_64) using EditLine wrapper The MySQL code used to create the user/password table. Which seems to work fine, and creates the table as it should - even though the resulting password doesn't appear to be quite right for SHA512-CRYPT INSERT INTO `mailserver`.`virtual_users` (`id`, `domain_id`, `password` , `email`) VALUES ('1', '1', ENCRYPT('firstpassword', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))), 'email1(a)example.com'), ('2', '1', ENCRYPT('secondpassword', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))), 'email2(a)example.com'); What it actually creates is this: This is not a SHA512-CRYPT password?? mysql> SELECT * FROM mailserver.virtual_users; 3 | 1 | $6jxK9DWPBrAc | robert(a)zeus.example.com Just to be clear,. this is the section of the Dovecot configs that deals with handling this. BUT.. On the MAC-Mini, SHA512-CrYPT is unknown. # List of supported schemes is in # http://wiki2.dovecot.org/Authentication/PasswordSchemes # default_pass_scheme = SHA512-CRYPT So the question is, what Encryption should I be using, and is this an Apple thing, or a MySQL thing?
