# Example attachment decoder script. The attachment comes from stdin, and
# the script is expected to output UTF-8 data to stdout. (If the output isn't
# UTF-8, everything except valid UTF-8 sequences are dropped from it.)
# The attachment decoding is enabled by setting:
#
# plugin {
# fts_decoder = decode2text
# }
# service decode2text {
# executable = script /usr/local/libexec/dovecot/decode2text.sh
# user = dovecot
# unix_listener decode2text {
# mode = 0666
# }
# }

# found from a filename of application/octet-stream. You can also add more
# extensions by giving more parameters.
