Handling imap from outlook 365
by Todd Krein 12 Sep '22

12 Sep '22

I apologize if this has been answered before, but... Microsoft Outlook 365 doesn't allow a user to specify the account name for an imap acout, only the email address. Thus fred(a)smith.com<mailto:fred@smith.com> tries to log in as "fred(a)smith.com<mailto:fred@smith.com>" rather than "fred". Has anyone seen a way to fix this (Microsoft help boards are silent), perhaps by stripping the "@smith.com" during the logon procedure?

Outlook 365 (RE: dovecot Digest, Vol 233, Issue 20)

Emilio, Thanks for the suggestions, but neither of these worked for me. Manual setup on Outlook 365 (I think as opposed to Outlook 202x), doesn't let you set the account name directly. It's being "helpful." Interestingly enough, if you set up as POP3, it realizes the account name is wrong and lets you enter it once you try to sync. Not so with IMAP. I was able to create the new account on the control panel, but outlook365 ignores all those accounts.

Unclear how to get both user and domain quotas to work
by Hans van Zijst 10 Sep '22

10 Sep '22

Hi, First of all: my apologies for this long message. I'm trying to post all the information anybody could need to help me on my way. What I'm trying to make is an installation where both users and domains can have quotas. Ideally I would configure a quota for a domain and set a quota of 0 for all users within that domain, so that mail will be accepted up to the point where the domain quota is reached. Setting up user quota was fairly easy, there's lots of documentation around and examples to take inspiration from. Not so much for domain quota however, or I'm really bad at searching the Net. I'm running Debian Bullseye here: MariaDB 10.5.12 Dovecot 2.3.13 Postfixadmin 3.3.10 I want to use dictionaries in MySQL, because eventually this will be a platform with several Dovecot and Postfix servers. At this time I'm only running one Dovecot installation and a few Postfix servers (two for communication with the outside world and one to do the virus and spam scanning). My current setup for user quota is how Postfixadmin wants it: MariaDB [postfixadmin]> desc quota2; +----------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------+--------------+------+-----+---------+-------+ | username | varchar(100) | NO | PRI | NULL | | | bytes | bigint(20) | NO | | 0 | | | messages | int(11) | NO | | 0 | | +----------+--------------+------+-----+---------+-------+ 3 rows in set (0.001 sec) In /etc/dovecot/conf.d/90-quota.conf I have this: plugin { quota = dict:User quota::proxy::sqlquota quota_rule = *:bytes=1024M quota_rule2 = Trash:bytes=+100M quota_vsizes = yes quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } The SQL-configuration /etc/dovecot/dovecot-dict-sql.conf.ext is this: connect = host=... dbname=... user=... password=... map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } I use LMTP to accept mail from Postfix; the quota-plugin is activated for LMTP, so every incoming mail should be counted. This works like a charm: if I don't configure a quota for a user, he gets the default 1GB, if I override it in Postfixadmin, then that's what he gets. I'm running quota-status on a TCP-port, so the gateway SMTP-servers can connect to Dovecot for a quotacheck to decide whether to accept or reject an incoming message. Again, this works flawlessly. I can't find any serious documentation about this mapping thing. In particular, what's with that "pattern"? All I can find in the documentation is: "The dict key must match exactly priv/quota/storage. The dict keys are hardcoded in the Dovecot code, so depending on what functionality you’re configuring you need to know the available dict keys used it." -- https://doc.dovecot.org/configuration_manual/dict/#dict-sql If anyone can point me at better documentation than the actual source code: please! I browsed through the quota-plugin source code, but I'm not a programmer and couldn't find what I thought I was looking for. That said, I'm not sure where I got the third "map" from, with the shared/expire pattern. I seem to have forgotten to document that bit of my journey. Now, domain quotas... I've tried all kinds of stuff, but at the moment I'm stuck with something that seems to almost work. I added a second quota root: plugin { quota2 = dict:Domain quota:%d:proxy::sqldomainquota quota2_rule = *:bytes=1024M quota2_status_success = DUNNO quota2_status_nouser = DUNNO quota2_status_overquota = "552 5.2.2 Domain quota exceeded" quota2_vsizes = yes } dict { sqldomainquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } This dict refers to the same mapping as the one for user quotas, and I think that's the way it should be. Please correct me if I'm wrong. This creates a new user in the quota2 table, by the name of just the domain. Unfortunately, it simply fills it with the numbers from the first user it can find in that domain, not all users in that domain combined. What I think I should do, is change something in the dict so that it sums up all users in that domain, something like this: SELECT SUM(bytes) FROM quota2 WHERE username LIKE '%@domain'; Problem is that I can't find anything useful online with regards to this, I'm not even sure if I'm thinking in the right direction here. Any hints, suggestions or corrections? Or pointers to articles or documentation I might have missed? Kind regards, Hans

Old-stats plugin and fifo_listener permissions
by Grant Keller 10 Sep '22

10 Sep '22

Hello, Currently working on using the old-stats plugin in dovecot version 2.3.10.1. What file permissions are recommended for the old-stats-mail and old-stats-user sockets? I was seeing a lack of data from the doveadm oldstats dump command until I adjusted the default config to the following: service old-stats { fifo_listener old-stats-mail { group = mode = 0666 user = root } fifo_listener old-stats-user { group = mode = 0666 user = } } Not totally clear on which processes need read or write on those so any advice is appreciated.

Managesieve not working
by Francis Augusto Medeiros-Logeay 09 Sep '22

09 Sep '22

Hi, I am running dovecot 2.3.7.2 on ubuntu, and have a replication setup. I noticed that managesieve doesn't seem to be working. On my backup MX, doing a telnet to 4190 gets me the proper greetings, but doing the same on my main server just gave me the normal telnet "Escape character is..." I get the following info on the server: root@d0ba5bb19b6b:/# doveadm service status managesieve name: managesieve process_count: 0 process_avail: 0 process_limit: 1024 client_limit: 1 throttle_secs: 0 exit_failure_last: 0 exit_failures_in_sec: 0 last_drop_warning: 0 listen_pending: n listening: y doveadm_stop: n But when attempting to connect, it doesn't work. Any advice? Best, Francis
