I just installed a certificate on my mail server to Postfix and Dovecot. The certificate is functional on Postfix, but for some reason I keep getting this error. Any suggestions on how to fix it? mail dovecot: imap-login: Error: SSL: Stacked error: error:1408A10B:SSL routines:ssl3_get_client_hello:wrong version number Here is my configuration: # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-45-generic x86_64 Ubuntu 16.04.6 LTS ext4 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain cram-md5 login auth_verbose = yes auth_verbose_passwords = plain base_dir = /var/run/dovecot/ disable_plaintext_auth = no mail_debug = yes mail_gid = 5000 mail_location = maildir:/home/vmail/%d/%n mail_plugins = quota mail_uid = 5000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota_rule = *:storage=5G sieve = /etc/dovecot/sieve/default.sieve sieve_default = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)example.com protocols = " imap sieve pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/certs/example.pem ssl_key = </etc/ssl/private/example.key userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static } verbose_ssl = yes protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota }

converting old uucp buffer files to maildir
by mh＠mike.franken.de 15 May '20

15 May '20

Hi *, besides my dovecot maildir structure, that has been migrated from an Exchange server, I have an even older mail structure in an ancient uucp style. The program named CrossPoint I used for this isn't wideley known, but it used so called mpuffer files in a plain text format. It is the program I still use to write for example this mail. I wonder if there already exists a program or script to convert the files from this program to the Dovecot maildir structure or some Howto for writing it myself. The format of these files looks like shown below.

doveadm sync backup from old to new server
by Gregory Sloop 15 May '20

15 May '20

So I've done quite a lot of searching on the list and on the web - and perhaps my google-fu is really bad - but I can't find any real recipes on how to sync mail from the old server to the new. As an FYI - the old server is a CPanel/WHM setup on a VPS. The new is mailcow - which uses docker. However, I don't think either of these platforms is what's causing the issue - but I'm certainly not sure of that. --- I've tried several things - but have lost track of all the things I've tried. This seemed like the best of all the things I've tried. This particular mailbox/user+domain is setup on both servers. doveadm backup -D -u mc-user(a)abc.net ssh root(a)abc.net -p2200 doveadm dsync-server -u cp-user(a)abc.net mc-user(a)abc.net is the MC/NEW mailbox/domain cp-user(a)abc.net is the CPanel/OLD user/domain account The SSH server of the remote system is running on port 2200. However when I try this, I get: WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string. dsync-local(user(a)abc.net)<v44NFyRWvF5efgAAb6OASA>: Error: read(remote) failed: EOF (version not received) doveadm(user(a)abc.net): Fatal: execvp(ssh) failed: No such file or directory The process appears to hang, and a Ctrl+C stops it. I'd love to get pointed at a reasonable recipe on how to make this work. I don't really get/understand the docs much at all. [And either everyone else understands it just fine, and never thinks to write a document on how to do it - or, and I think this is a lot more likely - they're using something like imapsync to do it. I found numerous places where others were, essentially, "Dovecot's tool is way too complicated and I can't get it to work right, so I used imapsync." I suppose I should probably just do that too, but it does seem a shame to do that when the dovecot tool is almost certainly the best tool for the job, but I can't figure out how to use it.] If someone can help me grok what's going on, I'm glad to write it up for the list and or a blog entry so it's more accessible. TIA -Greg

Can't connect to Managesieve Server - what´s wrong?
by Anton Blau 15 May '20

Hi, please excuse my bad english language. But I am not a native speaker. I have installed dovecot including sieve and managesieve on a ubuntu 18.04 lts. When I try to access the filter with roundcube (from another vm) I get the error message "Cannot connect to Managesieve-Server". If I try a "telnet myserver.dynvpn.de 4190" from the roundcube-vm I get Trying 188.194.95.63... Connected to myserver.dynvpn.de. Escape character is '^]'.

[Dovecot v2.3.9.3] HTTP API Endpoint for mailbox cryptokey operations
by Thibault HUTTIN-PASSERON 14 May '20

14 May '20

Hello everyone, I successfully set up the mail_crypt plugin using folder keys, and require user's key to be encrypted with a password using mail_crypt_require_encrypted_user_key = yes. As I'm trying to streamline the process of creating a user, and want to develop an application in PHP to help me in that process, I'm very interested in the doveadm HTTP API. Although the mail_crypt plugin is not referenced in the API, I discovered that it could be accessed all the same, provided some camelCase changes. So far I've been able to generate the following json for the mailbox cryptokey generate command: curl -X POST -H "Authorization: X-Dovecot-API <base64-api-token>" -H "Content-Type: application/json" -d '[["mailboxCryptokeyGenerate",{"user":"<username>","userKeyOnly":true},"tag1"]]' http://localhost:8081/doveadm/v1 which is able to give me the same output as the related command: doveadm mailbox cryptokey generate -u <username> -U. This only works if a keypair has already been generated for the user, which is kind of counter-productive in my use case. I would like to know if there was a way to adapt the following command into a json API call : doveadm -o plugin/mail_crypt_private_password=<password> mailbox cryptokey generate -u <username> -U Especially the -o plugin/mail_crypt_private_password=<password> part, since it seems I've figured out the other part partly tinkering partly looking through the source code. Thanks everyone for your input.

Hello, is it possible to compress by zlib only selected folders? My e-mail accounts have archive folder and this folder contains old comunications with my customers and this I use very rare, so I want to compress them by zlib to save space. Is this possible? Thanks, Filip Bartmann

Deleting messages from filesystem with sdbox mail format
by Gionatan Danti 11 May '20

11 May '20

Dear list, I recently had to delete some messages from an sdbox mailbox, for which I used the canonical "doveadm expunge" command without issues. However I got curious and, on a test mailbox, I deleted an unimportant message directly from the filesystem (rm u.650). After removing the file, the webmail continued to show it in the mail list - but no text was retrieved when I selected it. I supposed this was due to dovecot.index.cache and, indeed, deleting the cache got rid of the message in the webmail list. While I understand that it is not recommended (deleting and regenerating the index cache is an expensive operation), I wonder if removing a file from the filesystem, and regenerating the index cache file, is a safe operation when using an sdbox mailstore. Specifically, I would like to know if, after a manual filesystem deletion, the main index file (dovecot.index) is automatically updated by dovecot (reflecting the deletion) or if lingering references are kept in it.

My interest is for a Windows client, EM Client, which I otherwise really enjoy. Unfortunately, they've implemented server-side searching only via MULTISEARCH - for reasons passing my understanding. So I was hoping to hear Dovecot either already had support or there were plans to implement it. >>> >>> Virtual folder does not scale.
