[Dovecot] Implications of zlib plugin on search operations
Right now I'm compressing all mails older than 31 days and larger than 100k in size.
But what implications does this compression have on search queries performed by users (user looking for an old mail containing a certain string).

If you're not using any search indexes, then those will be read and uncompressed. So beyond using a little bit more CPU, nothing.

OK. Another zlib-related question: http://wiki.dovecot.org/Plugins/Zlib mentions "Compression while saving (v2.0+)) -- is there a size threshold for WHEN the compression fires? (e.g. mails larger than 5k)
