iMazing might be able to help you get the mail off the iPhone:

Then transfer to you Dovecot Maildir. (Have never done this - it’s just a

yes, if clients did pop3 setup to the server it works as designed, only

ask clients to make another imap setup, while keeping the pop3 setup, if

Seen-Flag and Virtual

[Dieter Knopf]

Hello,

We have a very large folder structure (in a public namespace) on our
Dovecot server and would now like to create a virtual folder
containing all mails of the publick namespace.

This worked quite well with dovecot-virtual, but the read status
(\seen) is not preserved.
i.e. when I read a mail inside the virtual folder, the read status
does not affect the original mail.

Dovecut was configured with per-user \seen-flag.

Is it possible to synchronize the \seen-flag somehow?

Thanks

Dieter

As expected.

doveconf -a shows all DEFAULT settings

doveconf -n shows your custom/current settings being used by the running
dovecot system.

What does doveconf -n show?

TMPFILE=$(mktemp)
cd /
tar cf "${TMPFILE}" \
./var/vmail/*/Maildir/new/1* \
./var/vmail/*/Maildir/.*/new/1*
scp -p "${TMPFILE}" remoteserver:/tmp/

Login to remote server:

cd /
tar xf /tmp/NAME_OF_TAR_FILE

moving only new mails from one server to another

[Nicolas]

Hello,

I think it is not really the right place to post about that, but lot of 
dovecot experts there ;)


Basically, I have a server with dovecot 2.2.9 that has new (unread) 
mails  (because of a bad DNS config at a migration time).


Is there an easy way to move only these unread mails to a another server 
? (no perms trouble here : all vmail:vmail)


Though to iterate through all /var/vmail/*/*/Maildir/new and scp/rsync them.

Would that work ?

Thanks in advance for your time.

Nicolas

Panic: file dsync-brain-mailbox-tree.c: line 448: unreached

[Marc Weustink]

Hi all,

To backup our imap folders I've a cronjob running in the night:
 /usr/bin/doveadm -o stats_writer_socket_path=  backup -R -A -N 
tcp:xxx.yyy.zzz:4191


This ran successful when I set it up and didn't look at it anymore.
Recently I noticed errors:

dsync-local(administration): Panic: file

I've added the dovecot repo to get dovecot automatically updated, so I 
cannot tell with which version it started.
