📝 Preliminary Checks
👀 What Happened?
I have the following setting in dovecot.cf
protocol imap {
mail_plugins = $mail_plugins zlib imap_zlib
}
# Enable these only if you want compression while saving:
plugin {
zlib_save = gz
zlib_save_level = 9
}
plugin {
## NOTE! Setting was called imap_zlib_compression_level before 2.3.15
## imap_compress_<algorithm>_level = value
##
imap_compress_deflate_level = 6
}
👟 Reproduction Steps
New mail that arrives in maildir is does not get compressed. These settings should save all new email compressed with gz.
