dovecot - Jan 2010 - handling filename of compressed messages

i'm running dovecot 1.2.9 and, among other things, i have the zlib 
plugin enabled. A shell script runs once a day to compresses all not 
still compressed files on the users maildirs.

    so far so good, it works fine, there's no problem on that.


    what i think is not happening 100% correctly is the following:

    1) user receives a message

    2) BEFORE the compress routine runs, filename is:

new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207

    3) AFTER the compress routine, filename is now:

new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz

    4) user check his mail .... and now the filename is

cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S

    5) user replies that mail .... and now the filename is

cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS


    i'm aware that dovecot doesnt need the '.gz' extension on the
file
to recognize that as a gzipped file. Even without the .gz extension, 
dovecot is correctly reading the file. the '.gz' is not even necessary 
on the filename and still dovecot can handle it fine.

    anyway, i would like to suggest dovecot to handle the filename to 
keep the .gz extension, if that exists. This could help sysadmins to 
easily identify gzipped files on the maildirs and make anything with 
them, if that's desired.

    i would like to see dovecot changing filenames properly and keeping 
the .gz extension always, for example

cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,S.gz
instead of
cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S

cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,RS.gz
instead of
cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS

The .gz is only wrong in the filename

No, you don't wont to have such file names.

http://wiki.dovecot.org/Plugins/Zlib: ? Dovecot can now read the file,
but to avoid compressing it again ? include e.g. a "Z" flag in the
file
name ? (e.g. 1223212411.M907959P17184.host,S=3271:2,SZ)

The article links also to: http://cr.yp.to/proto/maildir.html:
?
What can I put in info?
When you move a file from new to cur, you have to change its name from
uniq to uniq:info ? info starting with "2,": Each character after the
comma is an independent flag. ?

In short: You want to rename
1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207
to 1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,Z
