[Dovecot] new flags in Maildir files

[Giuliano Gavazzi]

Sorry if this is a dumb question:

I migrated my third system from courier to dovecot. My previous two  
were MacOSX the third is FreeBSD 6.
I noticed (because of an rsync process taking longer than usual...)  
that on FreeBSD the message files have, most of them at least, gained  
extra suffix letters (in the range a-h I'd say) that I do not see  
(mostly if not at all) on my MacOS systems. I wonder if this is  
because of a different migration process, as in the first two cases I  
wrongly run courier-dovecot-migrate.pl without the --convert option as  
I was satisfied that the OK result for all Mailboxes was enough... (no  
pop here), while on FreeBSD I correctly applied the --convert option.
The other difference is the version, 1.1.6 for MacOSX, 1.1.7 for  
FreeBSD.
Cannot find a relevant entryin the ChangeLog.
(now running rsync with the --fuzzy option, hopefully it will find the  
files cutting on transfer times!)

Thanks
