[Dovecot] Postfixadmin/MySQL/Dovecot 2 and quota
by Matt 01 Apr '20

01 Apr '20

Hi all, I'm setting up a new email server based on the softwares list below: * Postfix * Dovecot 2.0.9 * MySQL * Postfixadmin 2.3.6 My current problem is I'm unsure whether quota feature is well configured or not. In order to test and validate, I use Roundcubemail GUI which provides percentage of the space used by the mailbox (quota should be applied per mailbox). Here, my dovecot configuration: dovecot.conf: dict { quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } dovecot-… [View More]

mail_crypt crashing randomly during LMTP
by Andi Krischer 31 Mar '20

31 Mar '20

Hello everybody, hope you’re all well! We have a really strange bug with our dovecot setup. After weeks and month of debugging we’re finally reached the point when we ask you for help. Our basic setup is quite simple: a single dovecot 2.3.10 (0da0eff44) install on Debian 10 with LDAP as user/passdb and sieve, imap_sieve and mail_crypt as mail_plugins. For the mail_crypt we have a special rule which allows us to enable crypting for each user individually. See this line from dovecot-ldap.… [View More]conf.ext: pass_attrs = userPassword=password,=userdb_mail_plugins=%{if;%{real_lport};eq;993;imap_sieve;} %{if;%{real_lport};eq;143;imap_sieve;} notify mail_log %{if;%{ldap:encryptMail};eq;TRUE;mail_crypt; },=userdb_mail_crypt_private_password=%w As you can see for IMAP connections we enable imap_sieve and if the LDAP attribute “encryptMail” is set to TRUE we enable “mail_crypt” as mail_plugin. This works fine except that around 5-10 times a day the dovecot server crashes during a LMTP connection. It crashes in the last steps of LMTP which result that the mail get delivered to Maildir but Postfix doesn’t get a positive response and delivers the mail again after a few minutes. So all of our users get some mails twice or even more times. This is what the log says in the moment of crashing: dovecot: lmtp(53852): Panic: Module context mail_crypt_user_module missing *** backtrace *** (see: https://pastebin.com/YCiFtxmy) dovecot: lmtp(53852): Fatal: master: service(lmtp): child 53852 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) Here I’ve pasted the LTMP session in mail.log: https://pastebin.com/A4ughNUF Obviously it looks like it has something to do with our mail_crypt setup. But the thing is that although we’re monitoring this for months we cannot find a condition which cause this. It seems to happen more frequent for mails with lot of people in To or CC (large headers), but definitively not all of them… Some more things we’ve already thought on: First my guess was that the mail_crypt plugin isn’t loaded in some case but in the backtrace are things from “lib10_mail_crypt_plugin.so”, so it should be loaded, right? On the other hand a non-crashing LTMP session looks exactly the same in log except it has three additional lines in mail.log: Debug: Loading modules from directory: /usr/lib/dovecot/modules Debug: Module loaded: /usr/lib/dovecot/modules/lib15_notify_plugin.so Debug: Module loaded: /usr/lib/dovecot/modules/lib20_mail_log_plugin.so My college already had a look in the source code, but this didn’t make us much smarter. Here his references: mail context is defined here: https://github.com/dovecot/core/blob/81b5b188c478ec36bea8bda8fcad1e5f32ac61… and removed again here: https://github.com/dovecot/core/blob/81b5b188c478ec36bea8bda8fcad1e5f32ac61… Does any of the experts on this list have an idea what could cause these crashes and how to fix them? Thanks in advance! Best, Andi [View Less]

Help with migration to Dovecot from raw files
by Stefano Antonelli 29 Mar '20

29 Mar '20

Hello list, I recently migrated to Dovecot from a very old version of IceWarp running on failing hardware running Windows XP. I had a lot of issues downloading mail through imap. What I have instead are the email files directly off the harddrive from IceWarp's mail store. I rearranged the mail files to look like a Dovecot maildir and tried to use these emails directly. Dovecot did not complain, but I ran into my first problem. The emails were out of order on the client side. None … [View More]of my imap clients store email. They all just fetch headers and download mail as it's required. So a resync is not a problem. I just can't figure out how and I don't know if the filenames are a problem. The files I'm working with have this format: 2020032512105639B0-000001000000D2D45079615C.imap The first part is the date and all the the filenames appear to be unique. Is it okay to leave them this way or should I rename them in the same fashion as Dovecot? If so, is there a tool I can use or do I need to write a script? If I have to write a script, could someone help me decipher this filename: 1585197800.M440284P10160.hostname,S=2812,W=2875:2,S I understand the first bit is a unix timestamp. I couldn't find out what M440284P10160 means or how I might create that number myself to use in a renaming script. Additionally, I'd like to customise the hostname without changing the machine's hostname and I understand that the S and W can also be omitted. I'm not using quotas. I couldn't find anywhere in the documentation where it talked about any configuration options for the filenames. Are there any or do I have to patch the source? I was also planning on directly backing up the email using rsync, but the changing filenames with flags is obviously an issue. I understand that dovecot can store flags in a file instead, if the mailbox is shared or public. Is there any way to have this behaviour with a private mailbox? Ideally the filenames are not touched after creation in which case rsync will work nicely to my NAS. The last issue is that since Dovecot went live, I've started receiving mail. For the time being, I have left my "yet to be migrated" mail outside of maildir. So Dovecot doesn't know about it. I will need to merge this newly received mail with my "yet to migrated mail" once I sort out exactly how to migrate that mail. And I would really like all the mail to sort properly. From what I can tell doveadm is the tool for the job, but I just can't make sense of the documentation. Thanks, Stef Dovecot version: 2.3.4.1 (f79e8e7e4) [View Less]

At rest encryption (with protected crypto keys)
by Kees de Jong 25 Mar '20

Hi, As stated on the Dovecot documentation, at rest encryption is possible [1]. However, these keys are present on the system itself and are unprotected. Therefore, if a system is compromised, the attacker has access to the encrypted mail and the keys. There is no security benefit in that situation, except for hoping that the attacker doesn't understand that this is happening and how. Nextcloud does this a bit better. A key is used to encrypt user data as well [2]. However, that key is … [View More]

Hello! I have problems fetching mail for a system user. In use is a passwd-file. If I set (for virtual users) mail_uid = vmail mail_gid = vmail in 10-mail.conf, I get permission denied. 2020-03-23 18:39:23 imap(andreas(a)dualbit.de): Error: chdir(/home/andreas/Maildir/) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +x perm: /home/andreas/Maildir, dir owned by 5006:5006 mode=0700) The mailbox has permissions drwx------. 9 andreas susers If I don't set mail_uid I get an … [View More]error because of missing mail_uid. I can only access the users mailbox if I set mail_uid = 5006 in 10-mail.conf On another system I don't haver this problem. I made diffs, read alot of stuff and can't find a solution. What is the way to go, please? I would like to know why this does not work.
