Imapsync tips for the FirstClass IMAP server.

Q. From FirstClass to XXX
http://www.firstclass.com/
R. Migrating from FirstClass is not easy because FirstClass, strangely,
does not show all messages via IMAP. To make it show all messages,
a trick, painful to follow by hand, is moving emails
out and back in, for each folder. May be it can be done by a script.
FirstClass releases prior to release 12 do not shows the "Sent"
folder in IMAP but FirstClass release 12 shows it.
I advice you to upgrade to FirstClass release 12 before leaving it
with imapsync or another imap tool.
Here is a command line used to migrate from FirtClass release 12:
imapsync ... \
--tmpdir /var/tmp --usecache \
--useheader Message-ID \
--idatefromheader \
--addheader \
--regextrans2 "s,(/|^) +,\$1,g" --regextrans2 "s, +(/|$),\$1,g" \
--regextrans2 "s/[\^]/_/g" \
--regextrans2 "s/['\"\\\\]/_/g" \
--regextrans2 "s,&AC8-,-,g" \
--regextrans2 "s,&APg-,oe,g"
On Windows:
imapsync.exe ... ^
--automap ^
--usecache ^
--useheader Message-ID ^
--idatefromheader ^
--addheader ^
--regextrans2 "s,(/|^) +,$1,g" ^
--regextrans2 "s, +(/|$),$1,g" ^
--regextrans2 "s/[\^]/_/g" ^
--regextrans2 "s/['\\]/_/g" ^
--regextrans2 "s,^&AC8-,-,g" ^
--regextrans2 "s,^&APg-,oe,g"

Another advice with FirstClass as host1, do not use --delete1emptyfolders since
it will destroy all subfolders of any empty folder. This is a FirstClass bug:
when asked to list a non-empty folder it says it has no children while it does
have ones.
