Why do I receive keys I wouldn't expect

[Martin Jachs]

I issued the following command to receive my own public key for my other mail address "m.jachs at gmx.net".

gpg --keyserver sks-keyservers.net --recv-keys D870A352

and got the following output

gpg: requesting key D870A352 from hkp server sks-keyservers.net
gpg: key D870A352: "Martin Jachs (Regular email address) <m.jachs at gmx.net>" not changed
gpg: key E66B2314: public key "Forest Jordan <me at inetz.com>" imported
gpg: Total number processed: 2
gpg:               imported: 1
gpg:              unchanged: 1

My question now is: Why is the key for "me at inetz.com" imported? My key has only been signed by me and has no other user IDs than mine. The output from http://pool.sks-keyservers.net:11371/pks/lookup?op=vindex&fingerprint=on&search=0xB073838BD870A352 shows this.

I encountered this while importing my own public key on another machine (with Kleopatra) and got surprised.

Thanks for any explanation!

Martin
