Hi,
i try to migrate mails from a non dovecot imap server to a dovecot imap
server with doveadm backup as described there:
http://wiki2.dovecot.org/Migration/Dsync
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.
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:
Sometimes (every other time?) i got the following segmentation fault:

i think the problem could be that the account name on the remote server
and the local server is absolute identical and doveadm backup has
therefore problems discerning between the two locations. But that's only
a stab in the dark and any help is appreciated.
Kind regards
