You can't tell which compression is used in any arbitrary message since you need to be able to decrypt it first. If the message is to you, however, you can run 'gpg --list-packets' on it. When running list-packets, you should see a line like this: :compressed packet: algo=2 Algo 1 == ZIP Algo 2 == ZLIB Algo 3 == BZIP2 If there is no "compressed packet" line at all, then the message is uncompressed.
