During migration from 1.x with maildir to 2.x with dbox a did the
following trick:
time dsync -R -u t...@example.com backup
maildir:/var/spool/imap/tmp/Maildir
And got the following results:
|orig |366|28s |
|gz.6 |260|5min|
|bz2.6|202|5min|
|xz.1 |211|1min|
|xz.2 |213|1min50sec|
|xz.3 |201|3min|
|xz.6 |198|5min|
|xz.9 |198|10min|
|lz4 |281|18s |
1-9 - is compression level. I choose lz4 finally.

Hi,
may be someone has already done that: Do you have a script(?) tool
which
shows the efficiency of the mail compression if zlib is used?
Something that shows the uncompressed size vrs. the compressed.
Thanks for hints! /Götz
