i try to migrate mails from a non dovecot imap server to a dovecot imap server

i first tried (local-mailbox port 18143 is the non dovecot imap server):
/usr/bin/doveadm -o imapc_user=u...@example.org -o imapc_password=imappw -o
imapc_host=local-mailbox -o imapc_features=rfc822.size -o imapc_port=18143 -o
mailbox_list_index=no -v -D backup -R -f -u u...@example.org -m Sent imapc:
and got the following error:
dsync(u...@example.org): Fatal: dsync backup: Looks like you're trying to run
backup in wrong direction. Source is empty and destination is not.
Strange. -R is supposed to make it copy from imapc to mdbox.. Have you tried if
Dovecot can see mails at all from the remote server? Try doveadm -o mail=imapc:
-o ... fetch instead of doveadm backup command.
You're right it was an error in my setup that caused this problem. After
fixing that problem it now works as expected. The only thing I don't get
working is running it via the doveadm-server socket with:
/usr/bin/doveadm -o imapc_user=u...@example.org -o imapc_password=imappw
-o imapc_host=local-mailbox -o imapc_features=rfc822.size -o
imapc_port=18143 -o mailbox_list_index=no -v -D backup -S
/var/run/dovecot-director/doveadm-server -R -u u...@example.org imapc:
In the logfile on the server there is the following error message:
Jun 25 20:01:26 10.129.3.200 dovecot: dsync(u...@example.org): Error:
user u...@example.org: Initialization failed: Initializing mail storage
from mail_location setting failed: imapc: missing imapc_host
Jun 25 20:01:26 10.129.3.200 dovecot: dsync(u...@example.org): Fatal:
User init failed
So I think that all the -o configurations aren't transfered via the
doveadm-server socket.
As the dovecot imap account is newly created and therefore empty it seams to
try to backup from the dovecot imap server to the non dovecot imap server. So i
tried instead:
/usr/bin/doveadm -o imapc_user=u...@example.org -o imapc_password=imappw -o
imapc_host=local-mailbox -o imapc_features=rfc822.size -o imapc_port=18143 -o
mailbox_list_index=no -v -D backup -f -u u...@example.org -m Sent imapc:
Now this is copying from mdbox to imapc, which is also why you're getting the
crash:
Sometimes (every other time?) i got the following segmentation fault:
bt
#0 0x00007f15e2c9ed74 in strcasecmp () from /lib/libc.so.6
#1 0x00007f15e327eaff in imapc_save_callback (reply=0x7fff56096a70,
context=<value optimized out>) at imapc-save.c:168
Note how it's saving a mail to imapc. But still, that's a bug, fixed:
http://hg.dovecot.org/dovecot-2.1/rev/20703dbd1168
dsync(u...@example.org): Warning: Destination mailbox Sent has been modified,
need to recreate it before we can continue syncing
I think this is also because it's going to wrong direction.
Yes, the problem there was that it was the wrong direction.
