Assume I have the 3 public keys

store@abc.de
susi-store@abc.de
tom-store@abc.de

and want to send an email to

store@abc.de

the OpenPGP-plugin suggests to use the key of

tom-store@abc.de

because it found the word "store@abc.de" in "tom-store@abc.de". But this is in fact the wrong key. So it would be nice to correct this with the next update.

A first test shows that gnupg correctly selects the correct key thorugh --locate-key . But there might be a bug in the certificate resolution dialog.

Next step: Try to reproduce this.
