[Dovecot] unusual dsync lines

[Anand Kumria]

Hi,

$ doveadm sync -1 -r raw.log -R 'doveadm -o imapc_user=foo -o
imapc_password=bar -o mail=imapc: dsync-server'

I couldn't get that line to work, I get errors like:

doveadm(root): Fatal: Error reading configuration: Invalid -o parameter
imapc:: Missing '='
dsync-local(root): Error: read(remote) failed: EOF (version not received)
dsync-local(root): Panic: file iostream.c: line 37 (io_stream_unref):
assertion failed: (stream->refcount > 0)
*** glibc detected *** doveadm: corrupted double-linked list:
0x0000000002312620 ***

I have ended up doing:

$ doveadm -v -o imapc_user=user at example.com -o imapc_password=password -o
imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o
imapc_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no
sync -1 -r raw2.log -R -u user at example.com imapc:

I'll let you know if it finishes.

Thanks,
Anand
