[Dovecot] Convert MBOX

[Erin D. Hughes]

To all,

I am using dovecot --version 1.0.10 and trying to convert MBOXes to 
MailDir's with the end goal of creating one folder filled with users old 
MBOXes that when they log in for the first time will be converted to 
Mail Dir format.


I tried this and it did not work and gave me this output;
<snip>
 default_mail_env = maildir:%h/mail/
#convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u
 convert_mail = mbox:%h/mail/:INBOX=/usr/local/src/tmpmail/%u

This actually created the x4500-convert directory but did not populate it

Then I tried this trying to get the mail dir created and populated.

#convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u
convert_mail = mbox:/usr/local/src/tmpmail/%u:INBOX=/var/mail/%u

I am a little confused because when I read the syntax 
http://wiki.dovecot.org/Plugins/Convert?highlight=%28convert%29

It looks like it should say

"convert_mail= mbox:/users/home/dir/mail/:INBOX=/location/of/old/MBOX/file"

I have tried a number of different combinations but am still failing to 
get the mail/{cur,new,tmp} created in the correct user directory with 
actual mail in them.

Can some one please help w/this?

Additionally is there a way to run mail_convert on the command line to 
try to sort out the arguments? I noticed the converts are .so and .a in  
/usr/local/lib/dovecot/ so I doubt it but it can not hurt to ask.
