Bounced message after update
by Michael A. Peters 09 Feb '18

09 Feb '18

Hi - Updated from 2.2.27 to 2.3.0 server is webmail (roundcube) Sending worked before after update. Now it receives, but trying to send - this is the bounce in the log Feb 9 01:37:45 {hostname} postfix/pipe[22891]: 931FD2577: to=<{user}(a){hostname}.{tld}>, relay=dovecot, delay=0.01, delays=0/0/0/0, dsn=5.3.0, status=bounced (command line usage error. Command output: lda: Fatal: Invalid -f parameter: Missing domain ) Feb 9 01:37:45 deviant postfix/qmgr[16492]: 931FD2577: removed {hostname}, {user}, {tld} are substitutions. Here's my lda config: protocol lda { log_path = /home/{hostname}/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a){hostname}.{tld} } Any suggestions (other than reverting) ? This worked just before the update. If it matters, Roundcube 1.3.4

by Sergey Ivanov 08 Feb '18

Hi, What are the recommended ways to give access to their .dovecot.sieve.log messages to the users? I am thinking about placing this file into users Maildir/new, or piping to dovecot-lda. -- Regards, Sergey Ivanov

Cannot delete IMAP Mail-Folder in Trash
by Gabriel Kaufmann 08 Feb '18

08 Feb '18

Hello, I've noticed an annoying problem. Trying to delete a folder that has been deleted on IMAP and is moved to trash has problems being deleted. Thunderbird reports: "Folder contains children" and stops there. Folder at first disappears. But after restarting Thunderbird they are still there and on Dovecot-Mailbox folder on the server the folders are also still present. I'm using Dovecot 2.2.18 + Thunderbird + FS-Layout. I already tried this workaround-mode: > /protocol imap { //imap_client_workarounds = tb-extra-mailbox-sep //}/ best regards Gabriel Kaufmann _____________________________ TYPOWORX ΝΞШ.ΜΞDIΑ Gabriel Kaufmann Siegfriedstraße 38 | 38106 Braunschweig USt.Id Nr.

I also deleted Trash.sdb and Trash.msf in ImapMail-Dir of given Mailbox (after closing Thunderbird of course and restart afterwards). I think the repair-button does more or less the same than deleting msf-files. Trash was rebuilding... but the Folders are still there. I was able to get rid of some other "Junk folders" (that not even where shown in my Thunderbird-Trash inside Trash.sdb folder). But the folders causing current issue are still present after sync! And on server-side (vmail Mailbox on imap-server) these folders are also there! I'm still not able to delete them in Thunderbird. Still getting error Folder contains children, delete them first". Obviously this isn't possible as those sub-folders are not shown in Thunderbird! On server-side of imap (vmail Mailbox) there are in fact sub-folders in those folders. Best regards Gabriel Kaufmann
