testing with expunging messages with subject "delete me" this is the correct commend to list expunged messages?

[@ testtest]# doveadm search -u testtest mailbox test3 subject 'delete me' How can I get the amount of messages expunged in the folders? I do not get it.

I am trying to have mail from several shared mailboxes show up in a user's INBOX if they are unread or younger than 24h, using the filter "or (unseen) (all younger 86400)". This works when forcing dovecot to regenerate index files, as mentioned above, by adding spaces to the virtual Inbox config file. Otherwise, mail older than 24h is not removed from the virtual INBOX. Any help would be greatly appreciated :) namespace configuration: namespace lists { list = children location = maildir:/var/mail/lists:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists prefix = lists. separator = . subscriptions = no type = public } namespace real { hidden = yes list = no location = prefix = RealMails. separator = . } namespace vimap { hidden = yes list = no location = virtual:/var/mail/virtual/vimap:INDEX=~/Maildir/vimap prefix = vimap. separator = . } /var/mail/virtual/vimap: !RealMails all lists.* or (unseen) (all younger 86400) dovecot version: # 2.3.4.1 (f79e8e7e4) # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-14-amd64 x86_64 Debian 10.8 -Joe

dovecot.map.index corrupted: Unexpectedly lost INBOX uid=1 map_uid=4726

I had in my archive namespace[1] an INBOX folder and did not really get why it was there so I deleted it.

how to reclaim disk space mdbox
by Marc 15 Mar '21

15 Mar '21

When I delete messages in the archive namespace they are copied to the deleted items folder in the inbox namespace. This is 34MB increase is visible however I expected the archive to go down by 34MB. Is diskspace reclaimed automatically or do you need to issue an command? [@ sbin]# du -s -k /home/popusers/testtest /home/mail-archive/testtest 135472 /home/popusers/testtest 358824 /home/mail-archive/testtest [@ sbin]# du -s -k /home/popusers/testtest /home/mail-archive/testtest 169368 /home/popusers/testtest 358824 /home/mail-archive/testtest PS. I have mdbox_rotate_size = 4 M

Doveadm-Purge dry run

Maybe it is nice to introduce some option to Doveadm-Purge that does not delete anything just logs what it wanted to delete sort of like rsync's -n option.

archive namespace reports mdbox_deleted: same as mdbox: is that ok?

These commands should generate different output not?

Virtual users @ virtual domains / better documentation?
by justina colmena ~biz 15 Mar '21

15 Mar '21

I have configured postfix so it will deliver mail to virtual mailboxes. For some reason, the mail is not delivered to the virtual mailboxes unless both $virtual_alias_domains and $virtual_alias_maps are left undefined: these directives are apparently for aliasing virtual users "@" virtual domains to "real" unix users on the local system. --%%== # ADDRESS REDIRECTION (VIRTUAL DOMAIN) # # The VIRTUAL_README document gives information about the many forms # of domain hosting that Postfix supports. virtual_mailbox_domains = domain1.example.org domain2.example.com virtual_transport = virtual #virtual_alias_domains = domain1.example.org domain2.example.com virtual_mailbox_base = /var/mail/vhosts virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid = 100 virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 #virtual_alias_maps = hash:/etc/postfix/virtual ==%-- If the $virtual_alias_maps directive invalidates virtual mailboxes, then "the usual" aliases (postmaster@, etc.) for the virtual domains would have to be listed in /etc/aliases along with the non-virtual aliases, but this does not work either, and generates a warning when "newaliases" is run. postalias: warning: /etc/aliases, line 99: name must be local So as far as I can tell, no aliasing at all is available for "virtual_mailbox_domains" in postfix I am still unsure how to authenticate the virtual users on postfix. PAM authentication works fine for non-virtual users. The following command gives two options for authentication: cyrus-sasl and dovecot-sasl. # postconf -a cyrus dovecot Postfix also works with cyrus-sasl if the passwords are set in "/etc/sasldb2" via the "saslpasswd2" command, but dovecot doesn't seem to work with cyrus-sasl, and has its own type of sasl authentication. I realize this is not a postfix list, so my real question here is, What do I need in order for dovecot to authenticate the virtual users and allow them to read their mail and obtain authorization to send mail via postfix on the same system?
