[Dovecot] Configure deliver to add ', S=<size>' to maildir message name

Hi,

I want to use the zlib plugin to compress my mail storage. According to the wiki, only messages with size attribute in the message id should by compressed. If I added the size part, dovecot assumes it is a new message.

While dovecot undertands the ',S=<size>' attribute (IMAP shows that size), I could not configure deliver to add the size to message name.

I'm using dovecot v1.0.13

Regards,
