[Dovecot] maildir-tags

[Marten Lehmann]

Hello,

I configured my MTA to store messages in maildirs with a tag 
"S=$message_size", so quota calculations can be done without stat()ing 
the message file. However, I have a lot old messages, than haven't been 
stored with this tag. Is it possible to configure dovecot so that it 
will rename each file adding this messagesize-tag if it is not found in 
a file already?
