Postfix Dovecot Consultant Availability
by Asai 17 Feb '20

17 Feb '20

Greetings, We're in process of upgrading our Postfix / Dovecot installation, and would like to know if there are any qualified consultants out there that would be willing to work for us to help us verify and improve the deployment for our non-profit organization? This would be a fairly simple job of looking over configs and making recommendations, but may give way into more ongoing work. I know there are a lot of experts on this list that really know how Postfix and Dovecot work and we'd really appreciate some quality advice. I'm sending this request to both Postfix and Dovecot lists. Please email me directly with replies. -- Asai

Sieve setting a flag on the server (with sieve?)
by Marc Roos 17 Feb '20

17 Feb '20

I want to run a cron job for specific users. I thought the easiest would be a sieve plugin that sets some text in managesieve.sieve. And I just have my cron job check for this setting. This is the forward sieve: if false # true { redirect :copy "test(a)test.com"; } So maybe something like: if false # true { # cronjob1 } Or is there a better way of doing such a thing?

Question about noreplicate flag
by Bernardo Reino 17 Feb '20

17 Feb '20

Dear all, I've just setup replication between two servers. The e-mail accounts on both servers intersect but are not the same. In dovecot.conf (both are identical except one user /var/mail and the other uses /srv/vmail) I have: --<<-- userdb { driver = passwd-file args = username_format=%Lu /etc/dovecot/virtual_passwd default_fields = uid=vmail gid=vmail home=/var/mail/%d/%n } passdb { driver = passwd-file args = scheme=SHA512-CRYPT username_format=%Lu /etc/dovecot/virtual_passwd } -->>-- i.e. I use a passwd-like database. For the non-overlapping accounts in both servers I want to prevent replication, as it will otherwise fail with "Error: sync: Unknown user in remote". I have added "userdb_noreplicate" (also tried "userdb_noreplicate=y") for those users, but I still see the above error message in the logs. Like: reinob@bbmk.org:{SHA512-CRYPT}$6$e10...4c::::::userdb_noreplicate=y If I run "doveadm user -u reinob(a)bbmk.org" I get the following: userdb: reinob(a)bbmk.org user : reinob(a)bbmk.org uid : 5000 gid : 5000 home : /var/mail/bbmk.org/reinob noreplicate: y Note that I use "userdb_noreplicate" instead of "noreplicate" (which I also tried just in case), as from what I understood the "userdb_" prefix is required when adding the flag to the passwd file. As far as I can tell I'm doing everything right, but for some reason the replication is ignoring that flag. Thanks in advance for any help with this. (Let me know if you need to see the $(doveconf -n), but I believe the only relevant parts are the userdb and passdb.

Just to let you know that I also noticed that in a far past I created in the BSD root a symbolic link 'home -> usr/home'. That works for most programs, but obviously the use of this '/home' link in my old Dovecot config is not picked up by Dovecot as being redirected to '/usr/home'. ./joz

shared folder name or public folder with mail address
by Armin Schindler 16 Feb '20

16 Feb '20

Hello! we are about to move from cyrus to dovecot and have one open issue for that migration. With cyrus we have "shared/" folders with a name that is self defined like shared/project-xyz but the email address for direct delivery to that folder my be different (not project-xyz(a)domain.com). With dovecot we try to have it similar (at least how the user sees it in the client) like it is now. When configuring a namespace of type=shared, I see in the docs the the prefix can be configured with %%u , %%n or %%d. But is it possible to configure the name different to the email address? E.g. to hide the email address of that folder and show a nice name instead? I also thought about using public namespace instead. Does this make sense here? With public (maybe configured with prefix=shared/) folder I can set any name as subdir in prefix, right? So would this be more like what we have with cyrus shared folder? If so, how could these public folders have an email address for direct mail delivery into? Can something like a global sieve rule do that? Or can a public folder have an email address? Thanks in advance. Armin

doveadm backup -R -m -s not picking up a new message
by Daniel Shahaf 16 Feb '20

16 Feb '20

Good morning, I use «doveadm backup -R -m foo -s $state» to create a local mirror of an imapc remote folder. When I run that command, wait for it to finish, deliver a new message to the remote folder, and run that command again, the new message does not get downloaded from the remote. I'll attach the rawlog, doveconf, etc at the end. Allow me first to summarize what I've already checked: - I used «openssl s_client» to issue EXAMINE on the remote mailbox before and after delivering a mail to the remote mailbox, and HIGHESTMODSEQ does increase. - I looked at rawlog for both runs. doveadm issues a «STATUS foo (UIDNEXT UIDVALIDITY)» and receives a correct response (UIDNEXT in the second run is one larger than in the first run). - Other than that STATUS command, doveadm only issues LOGIN, LOGOUT, LIST, and LSUB commands. The remote server's responses do not report the new HIGHESTMODSEQ value for the folder. - The message does get mirrored locally when I run without the -s flag. I'm running dovecot 2.3.9.2 from FreeBSD ports. I've reviewed the FreeBSD port¹; it does have some patches, but none of them seem relevant to this issue. The remote server runs Cyrus. Debug output, etc follow: [[[ % doveconf -n # 2.3.9.2 (cf2918cac): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 12.1-RELEASE amd64 # Hostname: imapmirror.v.shahaf.local2 disable_plaintext_auth =

.IMAP
by Jos Chrispijn 15 Feb '20

Dear team, I have my users in /usr/home/user1 for user1, user2 for user2 etc. As these users also have a website, these folders have a /usr/home/user1/www folder, which is the docroot of their website. What happens now is that Dovecot indexes also this /usr/home/user1/www folder and creates in every folder a .imap folder which content is an exact image of the folder it is created in. In practice this causes 2 times of webspace (which also in on the account of that user). Can you pls tell me what I do wrong and how to solve this? I might be missing an 'exclude' folder setting for each dovecot user. Thanks for you expertise, Jos

Very slow mail download/notification with dovecot 2.2.33 and Thunderbird

Hi! I know that there are many results if I search for "dovecot thunderbird very slow" on Google but none of them helped me with my problem. :( I am running Ubuntu 18.04 (4GB RAM, 40GB HDD with EXT4) with the following software: - Dovecot 2.2.33 ---- All accounts are using Maildir ---- Sieve filters - Postfix 3.3.0 ---- with opendkim, spamassassin, razor, pyzor, .... And as IMAP client I am using Thunderbird 68.4 on Windows10. Sieve is used to sort incoming mails into my 224 folders (56 INBOX. folders and its subfolders (output of "find .INBOX.* -maxdepth 4 -type d -print |wc -l")). My problem is that it takes very very long to synchonize the INBOX and its subfolders. Even if there are only a few new messages to be downloaded. Sometimes Thunderbird outputs something like "downloading message 1 of 19" and it takes at least 60 seconds to download all of them. None of these 19 mails is larger than 5kB. And sometimes it seems that the transfer is suspended for a long time and it takes >5 Minutes to synchronize only a few mails. :( Every helpful advice is welcome. I just don't know where to look for the cause right now, but I can provide configurations (like output of |doveadm config) |and some logfiles. Thank you very much! Thorsten
