Before I go down the route of upgrading our main Solr instance from 6 to 7, just checking if anyone is using Solr 7 with Dovecot.

Re: Mail Alias Stores in mySQL Not working - SOLVED

"You have the alias abuse(a)kasdivi.com <mailto:abuse@kasdivi.com> for the address admin(a)theoceanwindow.com <mailto:admin@theoceanwindow.com> in your db and all mail to these aliases should go the the admin@ mailbox. Address mapping should be done in postfix so that the recipient address that gets used on the lmtp connection to dovecot is admin(a)theoceanwindow.com <mailto:admin@theoceanwindow.com> You probably disabled address mapping in postfix. -- Christian Kivalo” You nailed that .. I had completely forgotten about that.. I am changing a system from hash to SQL I actually feel kind of stupid I knew Postfix was supposed to do the acceptance.. and it should have been common sense that it need to rewrite.. The logs kept reminding me I had the following line in master,cf -o receive_override_options=no_address_mappings,no_header_body_checks,no_unknown_recipient_checks changed to -o receive_override_options=no_header_body_checks,no_unknown_recipient_checks and system works great.. Thanls!!

"So abuse(a)kasdivi.com <mailto:abuse@kasdivi.com> is an alias, not a user.? You can't login with an alias because your user_query is looking at the`mailbox` table. Have your tried logging in as: admin(a)theoceanwindow.com <mailto:admin@theoceanwindow.com> OR you could put an entry forabuse(a)kasdivi.com <mailto:forabuse@kasdivi.com> in your `mailbox` table. Bill” Bill Excuse me I must have some where mi-stated myself. Yes abuse(a)variousdoamns.com is an alias going back to my admin account The issue was iin my master.cf where I had at some time disabled remapping Fixed that and all is good Thanks for your time and effort.. You helped tremendously and actually had me discover some other issues Jason

Connection closed reason
by Miloslav Hůla 12 Oct '17

12 Oct '17

Hi, we have one user using the old Alpine client with IMAP. Time to time (3 times per day or 3 times per week) he get error: "MAIL FOLDER INBOX CLOSED DUE TO ACCESS ERROR" and he complains, that inbox stops to refresh with new emails. I don't know Alpine but I can imagine, that Alpine creates TCP connection to IMAPS and uses IDLE. I read wiki page about Timeouts [1] and it seems OK. Alpine is connected 5 or more hours without interrupt. But I found 'Connection closed' at approximate times of user reports in mail.log. Am'I undestand it correctly, that 'Connection closed' is some kind of incorrect connection end? I can find 'Logged out' messages which seems to me as correct ones. I can imagine that such situations may happend for moving clients, such a smartphone with losing signal. But mentioned user is on local network connected by cable. I'm interested, what exactly 'Connection closed' in mail log means. We have following lines in log: dovecot: imap(username): Connection closed in=63 out=288442 dovecot: imap(username): Connection closed (IDLE running for 0.001 + waiting input for 0.001 secs, 2 B in + 10+0 B out, state=wait-input) in=9668 out=17375 imap(username): Connection closed: read(size=3751) failed: Connection reset by peer in=4441 out=51431 dovecot: imap(username): Connection closed (UID fetch running for 0.008 + waiting input for 0.001 secs, 0.001 in locks, 101 B in + 202+202 B out, state=wait-input) in=3330 out=436043 Could it be problem in our network or Dovecot configuration issue? Can I somehow debug all connections for single client? Thank you, Milo [1] https://wiki.dovecot.org/Timeouts

Hmm, I see when using direct file access, but not when using IMAP, but I don't often connect this way with alpine). > Am'I undestand it correctly, that 'Connection closed' is some kind of > incorrect connection end?

I don't know what would cause this -- maybe some firewall state session timeout? Joseph Tam <jtam.home(a)gmail.com>

How to map email addresses to usernames?
by Andreas Born 12 Oct '17

12 Oct '17

Hello, I have a general question about userdb and passdb lookups, in my case related to driver=sql. The documentation and most examples in the internet seem to assume that a user's login username to access a mailbox is identical to his email-address, or at least to the local-part of this email-address. This setup works fine. But I don't understand how to setup dovecot, when login username and email adresses differ. Or to say it in other words, how to map email-adresses to mailbox users. I need a sql password_query for passdb to validate the password for a given login name during SMTP or SASL authentication. Lets say the credentials are "user-1"/"anypassword", then the query is similar to "select password from mailboxes where username='%u'". The next step, user_query for userdb is executed to get storage information for user "user-1". This query must also search for the username "user-1", not for an email-adress: "select home, mail from mailboxes where username='%u'". So far, so good. But: For incoming mails via LMTP, my user_query from userdb is being executed with the email-address as search parameter (instead of the login name), so it fails. I miss a third query that maps one user to each email address for delivery, prior to the userdb lookup. For Example: bob(a)example.org => user-1 eve(a)example.org => user-1 ted(a)example.org => user-2 @catchall.org => user-3 "select username from addr_maps where addr='%n@%d'". What is the correct setup for this szenario? I've found two solutions that seem to work, but i'm not sure if they are really failsafe. I) I use driver=prefetch as a first userdb, so for authentication, only the password_query from passdb is relevant and returns all mailbox details. A second userdb does a user_query lookup against email-addresses and is only called for incoming mails. passdb { driver = sql args = /etc/dovecot/sql-check-user.conf } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/sql-check-addr.conf } II) The second userdb performs lookups against usernames (as in the passwd query), but I place a third userdb {} within the lmtp's protocol section, which does a address lookup instead of a username lookup: protocol lmtp { userdb { driver = sql args = /etc/dovecot/sql-check-addr.conf } } passdb { driver = sql args = /etc/dovecot/sql-check-user.conf } userdb { driver = sql args = /etc/dovecot/sql-check-user.conf } What do you think, is there a better solution? - greetings Andreas Dovecot Version: 2.2.27 (c0f36b0)

Newbie question...
by Michael Segel 12 Oct '17

12 Oct '17

Hi, I’ve downloaded and built dovecot from the source. Now I’ve run in to a couple of issues. Like namespaces. Is there an example of the namespaces settings? Nothing fancy, just the basics… These are private mailboxes, but still need to know what I have to do to set this correctly. Thanks In Advance, -Mike
