Q. Couldn't create [INBOX.Ops/foo/bar]: NO Invalid mailbox name:
INBOX.Ops/foo/bar
Example:
sep1=/
sep2=.
Let begin by an explanation.
imapsync revert each separator automaticaly.
Example:
sep1 = /
sep2 = .
imapsync reverts each separator automaticaly.
a) All / character coming from host1 are converted to . (convert the separator)
b) All . character coming from host1 are converted to / (to avoid
intermediate unwanted folder creation).
So
INBOX/Ops.foo.bar (Ops.foo.bar is just one folder name) will be translated to
INBOX.Ops/foo/bar

Q: I'm trying to use imapsync on win32 for gmail, but it requires ssl,

Imapsync appears to require IO::Socket::SSL. What can I do?
R: (Q and R come as is from Bryce Walter)
R1: use standalone imapsync.exe, it contains IO::Socket::SSL
Perl module embeded.
I think I'm having success using cygwin perl instead of ActiveState
Perl. I wasn't able to get CPAN working and building IO::Socket::SSL
in ActiveState, but cygwin did all right. I had to force the install
of the Net::SSLeay dependency, because it partially failed one test,
but I think it worked anyway. In order to get working in cygwin, I
installed the entire "perl" category, lynx, ncftp, and lftp (specified
as ftp program in cpan setup). I'm not sure if I needed all those, or
if cpan just kept asking because I didn't have any installed at the
time. Anyway, cpan worked, and I installed all dependencies that
imapsync complained about until it started working.

Q. From Cyrus to Notes
Juhu! --useheader 'Message-ID' --skipsize does wonders! :)

Q. From cyrus to dbmail
R. (Given by Michael Monnerie, left as is)
dbmail creates a header like
X-DBMail-PhysMessage-ID:94348
on messages. There was another problem with cyrus, other headers get
modified also, so I recommend this for a full sync:
imapsync --host1 cyrushost --user1 u1 --password1 p1 \
--host2 dbmailhost --user2 u2 --password2 p2 \
--useheader 'Message-ID' \
--skipsize \
--syncinternaldates
I needed it because there are obviously some
encoding differences between the two servers, and modified headers lead
to all messages being doubled. Examples:
dbmail:
Content-Type:text/plain; format=flowed; charset=iso-8859-1;
reply-type=original
cyrus:
Content-Type:text/plain; format=flowed; charset="iso-8859-1";
reply-type=original
And also the "Received" headers got blanks added in DBmail, etc.
******************
For a full server copy from cyrus to dbmail I used:
imapsync --host1 cyrus --user1 x --authuser1 x --password1 x --ssl1 \
--host2 dbmail --user2 x --authuser2 x --password2 x \
--skipheader '(^X-|^Received|^MIME-|^Content-Type|^Disposition-|^From|^Cc|^Reply-|^Subject|^To|^DomainKey).*' \
--skipsize \
--sep1 '/' --exclude 'user/demo/Trash' \
--regextrans2 's/^user.//' --syncinternaldates
The 'exclude user/demo/Trash' was used because there was one message
there with 8 bit headers which dbmail doesn't accept, so I had to skip
the whole folder. It would be nice to have an option to just ignore
and log unsyncable messages, but do the rest, instead of stopping.
******************
There are two other major problems:
1) dbmail doesn't accept utf8 header, while cyrus does. imapsync stops
in that case, making sync impossible
To convert the whole messages from 8bit to 7bit, use option :
--regexmess 's/[\x80-\xff]/X/g'
(This is bad since only headers need this).
Default behavior might works.
