Change password schema and post-login script
Hello, Question #1: For version 2.3.19.1 these commands use BLF-CRYPT, right? doveadm pw doveadm pw -s CRYPT Question #2: I want to change password schema for current users. For users using POP3 or IMAP I can do it using a post-login script. I have some accounts used only to send e-mails using Postfix, so no POP3/IMAP logins for these accounts. Is any way to change password schema for these accounts?

Dovecot v2.3.7 - TLS/SSL issue
I use a helpdesk system that connects to dovecot using POP3 with SSL enabled to fetch the e-mails. After I upgrade to v2.3.7 the helpdesk randomly (some times it works, some times not) doesn't fetch the e-mails. If I configure the e-mail accounts with SSL/TLS disabled then it works. Any idea about this?
dovecot-uidlist path
When I use this: mail_location = maildir:/home/mail/%d/%n the dovecot-uidlist file is located in: /home/mail/example.com/user/dovecot-uidlist But when I change it to: mail_location = maildir:/home/mail/%d/%n:CONTROL=/var/mail/%d/%n then it's stored in: /var/mail/example.com/user/.INBOX/dovecot-uidlist Any idea why is not stored in: /var/mail/example.com/user/dovecot-uidlist ?

Re: lost connection while sending end of data error
By changing the postfix main.cf setting from the default: default_destination_recipient_limit = 50 to: default_destination_recipient_limit = 1 it solve the issue. Do you think it's a postfix issue so I have to use their mailing list? > On 19 Apr 2018, at 21:45, Christos Chatzaras wrote: > > I use dovecot-lmtp and postfix.

lost connection while sending end of data error
I use dovecot-lmtp and postfix. When I send e-mail to 2 recipients (or more) at the same time and if one of them is over quota (or under quota and the message I send is bigger than his free space) mailq shows: -Queue ID- --Size-- Arrival Time -Sender/Recipient--- 20B03336F2226099 Thu Apr 19 18:02:47 supp...@example.com (lost connection with server25.example.org[private/dovecot-lmtp] while sending end of data -- message may be sent more than once) us...@example.com us...@example.com E-mails sent from the same domain on same server so it's a local delivery. If I send the e-mail to the over quota user ( only him on To: ) then I get a bounce that says that user is over quota which is the correct behaviour. I think the problem started after I upgrade dovecot-2.2.35 to dovecot-2.3.1. Is this a known bug?
issue with sieve forwarding after upgrade to 0.5.1
Finally I found a workaround to not depend on sendmail to forward messages using sieve: In postfix main.cf I have: authorized_submit_users = root, filter (I want only root and filter to use sendmail and block other users to send e-mails from system accounts. Only allow users to send e-mails from virtual accounts and after smtp authentication. Username filter is used for bogofilter and needs access to sendmail) And in dovecot.conf: submission_host = 138.201.248.xxx The same workaround maybe works for NoNewPrivileges too as the authorized_submit_users setting in postfix has similar result.
Re: issue with sieve forwarding after upgrade to 0.5.1
It's similar issue but not the same. In my postfix main.cf I use: authorized_submit_users = root, filter to block users with shell access to send e-mails. I want only users root and filter to be able to send directly without using SMTP authentication. If I remove "authorized_submit_users = root, filter" then it works. The question is if something changed between postfix 2.2 and 2.3.1 which requires to drop privileges from root to user. > On 4 Apr 2018, at 12:25, B.

Here are some logs: Apr 3 23:25:35 server1 dovecot: lmtp(ch...@coderz.gr)<47735>: program `/usr/sbin/sendmail' terminated with non-zero exit code 75 Apr 3 23:25:35 server1 dovecot: lmtp(ch...@coderz.gr)<47735>: Error: sieve: msgid=: failed to redirect message to : Sendmail program returned error (temporary failure) In my postfix main.cf I have this: authorized_submit_users = root, filter When I change it to: authorized_submit_users = root, filter, myUserName where myUserName is the username that owns the mailbox it works.
