Hello,

I am trying to migrate a server with 10K accounts under courier Imapd
to Cyrus. I have got the imapmigrate from
http://sourceforge.net/projects/cyrus-utils/, but while I start the
script, it creates only empty folders. No messages are migrated to
Cyrus.

I tried the debug mode, I made many changes to imapmigrate script, but I
still couldn't get the old courier messages to cyrus.

Does anyone know what is wrong or can recommend any other migration
tool?

Thanks for any help

Christiano

I am attempting the same project.  I was looking at ImapSync and also just drag and dropping from thunderbird.  I 
noticed that Cyrus rejects any email with "invalid header" if the message has "From " 
(from_line) as the first line.  From my brief googling it appears the "From " thing looks to be/have been 
a standard Unix thing and procmail seems to append this into the message also.  Probably why I couldn't get 
postfix/procmail working with Cyrus, but that made me discover what sieve is. ;-)

I wonder if there some kind of switch in a conf file to make Cyrus accept "From " as a valid 
header?  This would make the migration much easier.  If not I will have to remove the "From " 
line in messages that have it.
