Convert MBOX Mail files into Maildir using Linux

*You need perl an the TimeDate module

Get the free Perl script mb2md from the project/author's site:
wget http://batleth.sapienti-sat.org/projects/mb2md/mb2md-3.20.pl.gz
gunzip mb2md-3.20.pl.gz

#remember you need timedate or you'll get this error:
./mb2md-3.20.pl

#*It needs an absolute path for -s (source) to work.  The destination by default is ~/Maildir unless you specify otherwise
[root@server.box thunderbird]# ./mb2md-3.20.pl -s /full/path/sbrewzer.default/Mail/mail.mailserver.com/Inbox

It worked perfectly, it turned everything into Maildir format and I literally just copied the appropriate folders directly into the IMAP folders from bash and everything worked (just make sure the correct/normal permissions are set on the copied files)
