Postfix / Dovecot Not Able to Authenticate

Hi My name is Keith Smith. I am a PHP developer and have been a freelance PHP developer since 2006. I have been working on a PHP web server in the hope of learning more about Linux hosting server administration. Over the years I have had the opportunity to create many PHP virtual hosts. I have not worked with or configured BIND, Postfix, and Dovecot before about 3 weeks ago. My home server is connected to the Internet via my home office business cable account. No blocked ports and I am able run one or more servers. I am running Ubuntu 20.04lts / Apache / MySql (or a clone) / PHP / BIND9 / Postfix / Dovecot / Let's Encrypt SSL. My server’s FQDN is : soho.keiththewebguy.com as is my reverse lookup on my IP : 98.191.108.149. The purpose is for learning. I intend to run one such configured server out of my home office running one domain or more (virtual hosts) and would like to configure Postfix/Dovecot to service one or more email addresses per virtual hosting. I have BIND working. At least enough that a simple web page can be displayed. I've installed Postfix and Dovecot and am getting an authentication issue that shows up in the logs. I do not know all that you might need. Please let me know. I admit I find Postfix and Dovecot difficult to understand. I am at the newbie stage. I've scoured the Internet looking for answers. After I configured Postfix and Dovecot I issued the commend : telnet keiththewebguy.com 25 on my web server. It returned: Trying 98.191.108.149... Connected to keiththewebguy.com. Escape character is '^]'. 220 soho.keiththewebguy.com ESMTP Postfix I issued : ehlo soho.keiththewebguy.com 250-soho.keiththewebguy.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250-DSN 250 CHUNKING I issued : quit 221 2.0.0 Bye Connection closed by foreign host. --- I assume this means things are configured correctly. I am looking at both logs: 1) /var/log/mail.err which contains no content. 2) /var/log/mail.log which is verbose. To /etc/dovecot/dovecot.conf I added the following for debugging: auth_verbose = yes auth_verbose_passwords = no auth_debug = yes auth_debug_passwords = yes mail_debug = yes verbose_ssl = yes I am trying to connect using Thunderbird. Config: IMAP port 993 / ssl/TLS / Normal Password / username : keith(a)keiththewebguy.com and password that is in /etc/dovecot/dovecot-users SMTP port 25 / STARTTLS / Normal Password / username : keith(a)keiththewebguy.com and password that is in /etc/dovecot/dovecot-users Thunderbird tests these configurations and reports them as found on the server. When I press the done button to create the email account I get a message "Unable to log into the server. Probably wrong configuration, username, or password.". The output when trying to create the Thunderbird account: /var/log/mail.log =============== Jul 5 18:58:35 soho dovecot: imap-login: Debug: SSL: where=0x10, ret=1: before SSL initialization Jul 5

master - master syncronization: *-temp-1-temp-1-temp-2-* recursion
by Heiko Schlittermann 05 Jul '21

05 Jul '21

Hi, I'm using dovecot 2.3.4.1 (f79e8e7e4) (Debian Build) and doing master/master replication. Recently we added a huuge .Archive* folder structure to the items being replicated. And now, suddenly we see new folders with a naming like *-temp-1-temp-1-temp-2-* appearing. This finally lead to infinite recursion until the replicator crashed. I've a theory, but please see below (**) for influence from outside of dovecot: SiteA starts replication of a huge .Archive folder, which doesn't exist on siteB yet A B .Archive ----> .Archive-temp-1 Because it takes ages to sync, the replicator on siteB now sees the new .Archive-temp-1 folder and starts replicating this back to siteA .Archive-temp-1-temp-1 <----- .Archive-temp-1 If now the replicator on siteA hits that new folder, it starts replicating it to site B .Archive-temp-1-temp-1 ----> .Archive-temp-1-temp-1-temp-2 … and so on. Sometimes the digit is "2", or even "3". I didn't check the Dovecot source yet, if the Replicator fails to skip the temporary folders it gets "injected" from the other side. (**) Possible external influence: On siteA a cronjob once per day moves the .Archive* folders to another filesystem and replaces the .Archive* directory with a symlink. This script "touches" the dovecot-uidlist.lock prior to its action (but doesn't check if there is already a lock). Could this mailbox move *behind* the back of the replicator be a reason for the odd behaviour? Additional info: On *both* nodes the config looks like this: doveadm_password = <password> service doveadm { inet_listener { port = 9090 ssl = yes } } replication_max_conns = 16 plugin { mail_replica = tcps:<other site>:9090 } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 user = dovecot } } service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = dovecot } unix_listener replication-notify { mode = 0666 user = dovecot } }

Duplicate users with multiple userdb iteration
by Slavko 05 Jul '21

05 Jul '21

Hi, recently i decided to use quota_over_flag with passwd_file userdb. The main idea is to prevent dovecot (or vmail) user to have write access to file with passwords. To do it, i setup separate userdb as this (SQL userdb is SQLite based, thus the same problem with write): passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { args = username_format=%u /etc/dovecot/over_quota default_fields = quota_over_flag=1 driver = passwd-file result_internalfail = continue-fail result_success = continue-fail } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } For testing i add one user into over_quota file: slavko(a)slavino.eu::::::: With this setting the doveadm user with user in over_quota seems to work: doveadm user slavko(a)slavino.eu field value uid 20000 gid 20000 home /srv/vmail/slavino.eu/slavko mail maildir:~/Maildir quota_over_flag 1 quota_rule *:storage=0M quota2_rule *:storage=0M But the user iteration shows duplicate users: doveadm user '*' slavko(a)slavino.eu slavko(a)slavino.eu ... As we discussed on IRC, it is how iteration works, as it emit users as soon as it meet it, but this doesn't correspond with "multiple userdb are merged" in docs (for iteration). I am surprised by this mainly because the particular userdb has set result_success to "continue-fail" and thus have to set user not found as with any user, which is not in this db. But it seems, that iteration ignores this result. I wrote this as we discussed via IRC, i am not subscribed, thus please CC me. regards -- Slavko http://slavino.sk

Hi , Thanks Erwan, Yes I did it.. what worries me is, that that instruction lsub "" * seems not to work.. I mean I am not allowed to see it b lsub "" * b NO [NOPERM] No permission to read subscriptions (0.001 + 0.000 secs). So not sure that this is the fault of Thunderbird :-) Thanks for your help

Bypass Trash Folder Sometimes.
by dovecot＠ptld.com 04 Jul '21

04 Jul '21

Is there a way, or a config setting, that would allow you to for-reals delete an email from the inbox instead of sending it to the Trash folder? Not always, the default behavior should still send deleted emails to the trash folder, but on a per case bases be able to just delete an email without it going to the trash folder. Same like how the windows desktop works. If you Delete a file on your desktop it goes to the recycle bin. However if you do Shift + Delete the file gets deleted without going to the recycle bin.

How can I prevent sieve filter from being applied to some mail users?
by yuryb 02 Jul '21

02 Jul '21

We have an emarket(a)example.com mailbox that receives orders from customers. Postfix redirects such emails to the email addresses of our sales managers, as well as to the special address parser(a)example.com, which is used by some analytical software. For this, a file named "Virtual" has been created in the Postfix folder with the following contents:emarket@example.com manager1@example.com,manager2@example.com,manager3@example.com,parser@example.comIn addition, Dovecot places all such emails in the Orders folder of each sales manager. For this, a Sieve filter rule has been created: require ["fileinto", "envelope"]; if envelope: is "to" "emarket(a)example.com" { fileinto "Orders"; stop; } But the problem is that the analytics software that uses the parser(a)example.com mailbox is subscribed only to the default Inbox folder. And it doesn't know how to work with the Orders folder. So I need to somehow prevent the filter from being applied to the parser(a)example.com mailbox. How can I do this using Dovecot or Sieve?
