[Dovecot] handling filename of compressed messages

[Leonardo Rodrigues]

    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
